I'm trying to detect faces from a video stream using OpenCV 2.4.8 with Java using detectMultiScale. When searching through the web I noticed two versions of it with different parameter lists. Like here:
detectMultiScale(image, faceDetections) in [here][1] and face_cascade.detectMultiScale( frame_gray, faces, 1.1, 2, 0|CV_HAAR_SCALE_IMAGE, Size(30, 30) )
When I used it inside my code it gives an error :
OpenCV Error: Bad flag (parameter or structure field) (Unrecognized or unsupported array type) in cvGetMat
When I debug the code I see that error occurs at line:
face_cascade.detectMultiScale(frame_gray, faces);
I'm confused with these two parameter method because in OpenCV documentation site they have only one method with seven parameters.
detectMultiScale(const Mat& image, vector<Rect>& objects, double scaleFactor=1.1, int minNeighbors=3, int flags=0, Size minSize=Size(), Size maxSize=Size())
Can anyone please describe what is this two parameter method and does it has any connection with the error in my code. Following is the code I was checking on:

OpenCV is written in C/C++. Java wrappers allows access to native code via JNI. Unlike C++, Java doesn't support default parameter values. That documentation is for C++ and so has one function with 5 default parameter values. To cover for that, OpenCV Java wrapper has 6 methods. The error you are getting, ideally shouldn't be because of this.
Try below.
capture.release() is called in loop. Release should happen outside while loop. Use like
while( !done ) { ... }
After capture.retrieve(frame);, add if( frame.empty() ) { continue; }

Recently i am working with Apache POI with Spring Boot and i am facing an issue. I want to represent database connections between entities, and i have a problem with visualizing multiple connections.
So the basic problem of mine is separating connections.
Here is my starting: 1
You can't see but there is multiple connections between this two rectangles, but because of the same start and end point, they are uncover each others.
The generated XML-code is the following:
<p:cxnSp>
<p:nvCxnSpPr>
<p:cNvPr name="Connector 7" id="7" />
<p:cNvCxnSpPr>
<a:stCxn id="2" idx="3" />
<a:endCxn id="3" idx="1" />
</p:cNvCxnSpPr>
<p:nvPr />
</p:nvCxnSpPr>
<p:spPr>
<a:xfrm flipV="1">
<a:off y="2199409" x="2616200" />
<a:ext cy="1318491" cx="2413000" />
</a:xfrm>
<a:prstGeom prst="curvedConnector3">
<a:avLst />
</a:prstGeom>
<a:ln w="9525">
<a:solidFill>
<a:srgbClr val="000000" />
</a:solidFill>
</a:ln>
</p:spPr>
</p:cxnSp>
So what i want to do is set the curved conectors midpoint in a different values, like in this image (i do this manually for the example):
2
I try to add some other GeomGuide element to the connector but the result is an unstable pptx file with this:
<a:prstGeom prst="curvedConnector3">
<a:avLst>
<a:gd name="adj1" fmla="val 57365" />
</a:avLst>
</a:prstGeom>
Relevant java code snippet for this:
XSLFConnectorShape connector1 = slide.createConnector();
CTNonVisualConnectorProperties cx = ctConnector.getNvCxnSpPr().getCNvCxnSpPr();
CTConnection start = cx.addNewStCxn();
start.setId(shapeIdStart);
start.setIdx(rel.getStartSide());
CTConnection end = cx.addNewEndCxn();
end.setId(shapeIdEnd);
end.setIdx(rel.getEndSide());
CTGeomGuideList ctGeomGuideList = ctConnector.getSpPr().getPrstGeom().getAvLst();
CTGeomGuide ctGeomGuide = ctGeomGuideList.addNewGd();
ctGeomGuide.setName("adj");
ctGeomGuide.setFmla("val 45000");
Your provided code snippet is not complete. So it is not clear whether this is the one and only problem. But ctGeomGuide.setName("adj"); is wrong in any case. The adjust handles are numbered and there is no adjust handle called adj only. It would must be ctGeomGuide.setName("adj1");.
Folowing code is a Minimal, Reproducible Example which works and creates your wanted result.

I'm currently working on functionality, that is supposed to generate stacked chart inside .pptx file.
For this I'm using code from here:
java create a chart in a powerpoint using APACHE POI
I did some modifications. Mainly I set grouping to Stacked and overlap to 100 (so the subBars looks like one bigger bar).
Now I need to display SUM of subBars values above each Bar. Aaaaand here comes my question. How can I achieve this (second pohoto below) using Apache Poi and openxmlformats.schemas.drawingml.x2006.chart?
One idea was to create another SubBar on top, make it transparent and set it's label to my desired SUM, but I cannot find a way, to set label (only Value and in this case, my transparent SubBar takes too much space and it just looks terrible - as in the photo below).
This is what I need it to look like:
I cannot find any documentation or anything apart from some threads here on StackOverflow.
Do you guys have some idea, on how to achieve this?
EDIT 1
With help from Alex I was able to print SUM values above BARs. Now I just need to get rid of these 0 values:
EDIT 2
There was a problem mentioned by Axel, that caused zeroes to be displayed (from EDIT 1). Axel edited the code in his answer, so now zeroes are gone.
How would you do that using PowerPoint? The only way I see is using a combination of stacked bar chart with line chart where the line chart displays the sum values and is set invisible. So only the data labels of the line chart are visible. The way as described in How to add total labels to stacked column chart in Excel?.
Using current apache poi 4.1.2 this can be achieved using the new XDDF stuff. For a Excel chart, I have shown that in How to generate editable Stacked-bar-chart using apache poi 4.0.1 and java?.
I will show a complete example for a PowerPoint chart as well:

I have written the following code using Apache Batik in order to generate SVG images (full source available on GitHub) representing badges showing if code passes a SonarQube quality gate or not:
private SVGGraphics2D generateFor(final QualityGateStatus status) {
// new SVG graphics
final SVGGraphics2D svgGraphics2D = new SVGGraphics2D(this.svgGeneratorContext, false);
// set SVG canvas size
svgGraphics2D.setSVGCanvasSize(new Dimension(LABEL_WIDTH + status.displayWidth(), CANVAS_HEIGHT));
// set font
svgGraphics2D.setFont(FONT_FAMILY);
// draw Label background
svgGraphics2D.setColor(COLOR_BACKGROUND_LABEL);
svgGraphics2D.fillRoundRect(0, 0, LABEL_WIDTH, CANVAS_HEIGHT, BACKGROUND_CORNER_ARC_DIAMETER, BACKGROUND_CORNER_ARC_DIAMETER);
svgGraphics2D.fillRect(LABEL_WIDTH - BACKGROUND_CORNER_ARC_DIAMETER, 0, BACKGROUND_CORNER_ARC_DIAMETER, CANVAS_HEIGHT);
// draw Label text shadow
svgGraphics2D.setColor(COLOR_SHADOW);
svgGraphics2D.drawString(LABEL_TEXT, X_MARGIN, Y_OFFSET_SHADOW);
// draw Label text
svgGraphics2D.setColor(COLOR_TEXT);
svgGraphics2D.drawString(LABEL_TEXT, X_MARGIN, Y_OFFSET_TEXT);
// draw result background
svgGraphics2D.setColor(status.displayBackgroundColor());
svgGraphics2D.fillRoundRect(LABEL_WIDTH, 0, status.displayWidth(), CANVAS_HEIGHT, BACKGROUND_CORNER_ARC_DIAMETER, BACKGROUND_CORNER_ARC_DIAMETER);
svgGraphics2D.fillRect(LABEL_WIDTH, 0, BACKGROUND_CORNER_ARC_DIAMETER, CANVAS_HEIGHT);
// draw result text shadow
svgGraphics2D.setColor(COLOR_SHADOW);
svgGraphics2D.drawString(status.displayText(), LABEL_WIDTH + X_MARGIN, 15);
// draw result text
svgGraphics2D.setColor(COLOR_TEXT);
svgGraphics2D.drawString(status.displayText(), LABEL_WIDTH + X_MARGIN, 14);
return svgGraphics2D;
}
Examples of produced images (depending on parameters passed to the generateFor() method) can be seen on GitHub as well.
This code works fine, however currently the weight of a generated image is more or less 2KB, which is almost 3 times heavier than travis-ci badges that weight more or less 700 Bytes. Therefor I have the feeling that generated images could be simplified, sized down to ~1KB.
How can I achieve this using Apache Batik ? Should I use another library or use another approach ?
Thanks in advance for your insight and recommendations !
I tried generating your SVG using JFreeSVG 3.0, and with the GZIP option it creates files around 570 bytes. In plain text the SVG is around 1.7 kbytes.
Here is the test program I ran (based on your code, you'll also need your QualityGateStatus class to run this):

System.out.println(aryLines[i]);
if(aryLines[i].startsWith("makeGrass:")) {
String Arguments = aryLines[i].substring(aryLines[i].indexOf(":")+1, aryLines[i].length());
String[] ArgArray = Arguments.substring(1, Arguments.length() - 2).split(" ");
this.makeGrass(Double.parseDouble(ArgArray[0]),
Double.parseDouble(ArgArray[1]),
Double.parseDouble(ArgArray[2]));
}
}
} catch(IOException e) {
System.out.println(e.getMessage());
}
}
and my text file would only have one line:
makeGrass:(x y z) // for example makeGrass:(1.22334 0.0 9.66678)
this all works fine now.. but there's no point in making this for only one single object. What I want to be able to do is have as many objects as I want from multiple coordinates, so my text file might look like this:
makeGrass:(0.0 1.0 5.0)
makeGrass:(8.0 1.0 2.0)
makeGrass:(4.0 1.0 7.0)
makeGrass:(0.0 1.0 2.0)
makeGrass:(2.0 1.0 7.0)
makeGrass:(5.0 1.0 6.0)
at the moment I use the code this.makeGrass only once and like that my grass model is only placed at those coordinates of the first line (the other lines cause a graphical glitch where they are just being put ontop of each other)
My question here is how I have to write the code so it gives me this.makeGrass multiple times: I want to render the grass model at the respective makeGrass coordinates as many times as there are makeGrass coordinates provided in the text file, how can I do that?
Thanks for any help!
edit: I was asked for more information.. here it is:
public class Vegetation extends GameComponent
{
private Game game;
GameObject grassLeaf1 = new GameObject();
Mesh grassLeaf1mesh = new Mesh("grassLeaf1.obj");
Material grassLeaf1material = new Material
(new Texture("GrassUVTex.png"), 1, 8, new Texture("GrassUVTex_NRM.jpg"), new Texture("GrassUVTex_DISP.jpg"), 0.008f, -0.5f);
MeshRenderer grassLeaf1Renderer = new MeshRenderer(grassLeaf1mesh, grassLeaf1material);
public Vegetation(Game game)
{
this.game = game;
}
public void makeGrass(double posX, double posY, double posZ)
{
grassLeaf1.AddComponent(grassLeaf1Renderer);
grassLeaf1.GetTransform().GetPos().Set((float)posX, (float)posY, (float)posZ);
grassLeaf1.GetTransform().SetScale(new Vector3f (2, 2, 2));
grassLeaf1.GetTransform().SetRot(new Quaternion(new Vector3f(0, 1, 0), (float) Math.toRadians(0)));
game.AddObject(grassLeaf1);
}
public void ProcessText()
{
grassLeaf1.AddComponent(new SaveGrass());
grassLeaf1.AddComponent(new ObjectManipulator(4.0f));
String file_name = "C:/Users/Server/Desktop/textText.txt";
try
{
ProcessCoords file = new ProcessCoords(file_name);
String[] aryLines = file.OpenFile();
int i;
for (i = 0; i < aryLines.length; i++)
{
System.out.println(aryLines[i]);
if(aryLines[i].startsWith("makeGrass:")) {
String Arguments = aryLines[i].substring(aryLines[i].indexOf(":")+1, aryLines[i].length());
String[] ArgArray = Arguments.substring(1, Arguments.length() - 2).split(" ");
this.makeGrass(Double.parseDouble(ArgArray[0]),
Double.parseDouble(ArgArray[1]),
Double.parseDouble(ArgArray[2]));
}
}
} catch(IOException e) {
System.out.println(e.getMessage());
}
}
}
The Vegetation Class handles creating a grass model and reading the coordinates of it from a text file. This here is said text file:
makeGrass:(0.6 1.0 2.8)
makeGrass:(5.6 1.0 9.8)
makeGrass:(2.6 1.0 4.8)
makeGrass:(7.6 1.0 3.8)
makeGrass:(0.6 1.0 2.8)
makeGrass:(0.6 1.0 4.8)
makeGrass:(2.6 1.0 2.8)
makeGrass:(0.6 1.0 0.8)
Now this should enable me to render 8 grass models at different positions but when I hit run all I can see is this:

the grass is also super shiny because all other grass models are being placed also at this location.. something went wrong..
Okay I've found the mistake my make grass function was messed up, it needs to be like this:
public void makeGrass(double posX, double posY, double posZ)
{
GameObject grassLeaf1 = new GameObject();
Mesh grassLeaf1mesh = new Mesh("grassLeaf1.obj");
Material grassLeaf1material = new Material
(new Texture("GrassUVTex.png"), 1, 8, new Texture("GrassUVTex_NRM.jpg"), new Texture("GrassUVTex_DISP.jpg"), 0.008f, -0.5f);
MeshRenderer grassLeaf1Renderer = new MeshRenderer(grassLeaf1mesh, grassLeaf1material);
grassLeaf1.AddComponent(grassLeaf1Renderer);
grassLeaf1.GetTransform().GetPos().Set((float)posX, (float)posY, (float)posZ);
grassLeaf1.GetTransform().SetScale(new Vector3f (2, 2, 2));
grassLeaf1.GetTransform().SetRot(new Quaternion(new Vector3f(0, 1, 0), (float) Math.toRadians(0)));
game.AddObject(grassLeaf1);
}
only strange that once I've added the code into the makeGrass method I lost my input methods.. strange but not that of a problem for now..
I'm getting almost exactly what I wanted now.. here's the final result and the basis of my world editor. Thank you all very much, you've really helped me!
Here's my ShowOff picture: http://www.pic-upload.de/view-27752521/ShowOff.png.html
I'm sure I'll be back for more soon enough but at the moment I know everything and can extend this world editor on my own, thanks a lot to all who have helped me so far, hopefully I can return the favour some time!
I'm creating shapes with extrude geometry on GWT, now I want to apply textures on it but I am not able to apply it directly. How can I do that?
My code looks like :
ExtrudeGeometry extrudeMaterialBoard = null;
shapeExtrude.getExtrudeSettings().amount = (int) getMaterialThickness();
shapeExtrude.getExtrudeSettings().curveSegments = 1;
shapeExtrude.getExtrudeSettings().bevelThickness= 5;
shapeExtrude.getExtrudeSettings().bevelSize= 5;
shapeExtrude.getExtrudeSettings().bevelEnabled= true;
shapeExtrude.getExtrudeSettings().material = 0;
shapeExtrude.getExtrudeSettings().extrudeMaterial = 1;
extrudeMaterialBoard = new ExtrudeGeometry(DrawShape.getBottomBoard(), shapeExtrude.getExtrudeSettings());
camera = new PerspectiveCamera(
70, // fov
getRenderer().getAbsoluteAspectRation(), // aspect
1, // near
1000 // far
);
camera.getPosition().setZ(400);
String texture1 = "uvgrid0.jpg";
MeshBasicMaterial material = new MeshBasicMaterial();
material.setColor(getColor(COLOR_TRANSPARENT));
Texture texture = new Texture(texture1);
material.setMap(texture);
mesh = new Mesh(extrudeMaterialBoard, material);
getScene().add(mesh);
getRenderer().render(getScene(), camera);
If I use cube geometry then its running properly. But in case of extrude geometry its not working.
Thanks in advance.
