how to import a mat value in openCV

how to import a mat value in openCV - java

I exported many CalcHist mat-values into a file and build an average of the values. Now I want to import it back into my Java Programm (static in the Code or import as file, it doesn't matter) to compare the calculated average hist with a hist of an given Image. The problem is that I don't know how to import the values into a Mat variable.
Example hist-values:
[680.365; 898.065; 583.155; 971.535; 454.825; 202.34; 213.26; 316.98; 449.765; 9902.57; 357078.595; 1292.21; 521.705; 157.985; 109.985; 137.685; 301.395; 127.58; 0; 0; 0; 0; 0; 0]
If I implement it as a static value with MatOfDouble (I don't have an idea to do it in another way) like this:
MatOfDouble averageHist= new MatOfDouble(680.365, 898.065, 583.155, 971.535, 454.825, 202.34, 213.26, 316.98, 449.765, 9902.57, 357078.595, 1292.21, 521.705, 157.985, 109.985, 137.685, 301.395, 127.58, 0, 0, 0, 0, 0, 0);
I can use the variable for a compareHist like this:
double res= Imgproc.compareHist(baseHist, averageHist, Imgproc.CV_COMP_CORREL);
and compile it, but at runtime it will throw a exception.
the programm works, if I only use Mat values that I directly get from calchists like the variable baseHist, but for averageHist I want to put it static in the Code or read it from a file.
I tried to cast the MatOfDouble into a normal Mat like this:
Mat averSunnyHistCast = new Mat();
averSunnyHistCast = (Mat) averageHist;
but it doesn't help.
this is the error:
CvException [org.opencv.core.CvException: cv::Exception: C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\imgproc\src\histogram.cpp:2281: error: (-215) H1.type() == H2.type() && H1.depth() == CV_32F in function cv::compareHist
thanks for your help!

This post helped: OpenCV How to initialize Mat with 2D array in JAVA
I wrote my values static in an array, after that I added each value into the Mat variable with the put method.
double[] dblArr = {650, 1230, 257, 66, 38, 19, 20, 33, 75, 15617, 350640, 2737, 1251, 547, 325, 328, 417, 150, 0, 0, 0, 0, 0, 0, 0};
Mat averageHist = new Mat(25, 1, CvType.CV_32F);
for (int i=0; i<25; i++){
averSunny200.put(i, 0, dblArr[i]);
}

StringUtils.containsIgnoreCase() is returning wrong result

i have two values:
String a = "00tz"; // (Eclipse internal debug value: [, 0, 0, t, z]) and
String b = "tz"; // (Eclipse internal debug value: [, t, z])
I am reading this values from an ArrayList like
for (String a : stringLists) {
...
}
I get "false" when i compare this two values with StringUtils.containsIgnoreCase(a,b). But it should return true because "tz" is existing in "00tz".
Im using apache.commons.lang3.StringUtils. To change the values a & b didn't worked. The length of "a" is 5 and "b" is 3. It also returns false when i use a.contains(b).
These are the results when i output the value with
System.out.println(Arrays.toString(a.getBytes(StandardCharsets.UTF_8)));
a:[-17, -69, -65, 48, 48, 118, 119]
b:[-17, -69, -65, 118, 119]
Im reading this values from a .txt file which contains several values like this. I read it in this way:
File fileA = new File("test/a.txt");
File fileB = new File("test/b.txt");
lista = (ArrayList<String>) FileUtils.readLines(fileA, "utf-8");
listb = (ArrayList<String>) FileUtils.readLines(fileB, "utf-8");
Do you have an idea what the problem is?
Thank you!

JavaCV assertion failed

I am trying to use K-means JavaCV implementation, but I have the following error:
OpenCV Error: Assertion failed (!centers.empty()) in cvKMeans2, file src\matrix.cpp, line 4233
My source code is:
IplImage src = cvLoadImage(fileName, CV_LOAD_IMAGE_COLOR);

int attempts = 10;
CvTermCriteria termCriteria = new CvTermCriteria(TermCriteria.EPS + TermCriteria.MAX_ITER, 10, 1.0);
cvReshape(src, src.asCvMat(), 1, src.height() * src.width());
IplImage samples = cvCreateImage(cvGetSize(src), src.depth(), 1);
cvConvertImage(src, samples, CV_32F);
IplImage labels = cvCreateImage(new CvSize(samples.height()), 1, CV_8U);
IplImage centers = cvCreateImage(new CvSize(cluster_count), 1, CV_32F);
cvKMeans2(samples, cluster_count, labels, termCriteria, 1, new long[attempts], KMEANS_RANDOM_CENTERS, centers, new double[attempts]);
I'm beginner on JavaCV and would to know what I doing wrong in this code?

OpenCV 3.0 svm always predicts 0 (java)

I'm new to opencv's svm's. I tried a sample classifier but it only returns 0 as the predicted label. I even used the value 5 for training as well as the prediction.
I've been changing the values for about a hundred times but i just don't get what's wrong. I'm using OpenCV 3.0 with Java. Here's my code:
Mat labels = new Mat(new Size(1,4),CvType.CV_32SC1);
labels.put(0, 0, 1);
labels.put(1, 0, 1);
labels.put(2, 0, 1);
labels.put(3, 0, 0);
Mat data = new Mat(new Size(1,4),CvType.CV_32FC1);
data.put(0, 0, 5);
data.put(1, 0, 2);
data.put(2, 0, 3);
data.put(3, 0, 8);
Mat testSamples = new Mat(new Size(1,1),CvType.CV_32FC1);
testSamples.put(0,0,5);
SVM svm = SVM.create();
TermCriteria criteria = new TermCriteria(TermCriteria.EPS + TermCriteria.MAX_ITER,100,0.1);
svm.setKernel(SVM.LINEAR);
svm.setType(SVM.C_SVC);
svm.setGamma(0.5);
svm.setNu(0.5);
svm.setC(1);
svm.setTermCriteria(criteria);
//data is N x 64 trained data Mat , labels is N x 1 label Mat with integer values;
svm.train(data, Ml.ROW_SAMPLE, labels);
Mat results = new Mat();
int predictedClass = (int) svm.predict(testSamples, results, 0);
Even if i change the lables to 1 and 2, I still get 0.0 as a response. So something has to be absolutely wrong... I just don't know what to do. Please help! :)

I had a similar problem in C++. I'm not too sure if it's the same in Java but in C++ the predictions were saved in the results Matrix instead of returned as a float.

Creating 24bit BMP fails (only with a particular resolution)

I'm creating a 24bit bmp which in general works fine (I've been using this functionality for some time). Now I've tried to write a bmp with 970 x 970 pixels and I'm ending up in corrupt files (I've exported bigger images before, I'm having problems with this particular resolution).
This is how I build the header:
private static byte[] createHeader(int width, int height) {
int size = width * height * 3 + 54;
byte[] ret = new byte[54];
set(ret, 0, (byte) 'B', (byte) 'M');
set(ret, 2, intToDWord(size));
set(ret, 6, intToDWord(0));
set(ret, 10, intToDWord(54));
set(ret, 14, intToDWord(40));
set(ret, 18, intToDWord(width));
set(ret, 22, intToDWord(height));
set(ret, 26, intToWord(1));
set(ret, 28, intToWord(24));
set(ret, 30, intToDWord(0));
set(ret, 34, intToDWord(width * height * 3));
set(ret, 38, intToDWord(0));
set(ret, 42, intToDWord(0));
set(ret, 46, intToDWord(0));
set(ret, 50, intToDWord(0));
return ret;
}
Here is the resulting image (this test image should be completely red):
test_corrupt.bmp (2.6mb)
I've analyzed the header, checked the size, I can't find the reason why this image is not a valid BMP.
Does anyone have a clue? I'm not making any progress.

It may be because of BMP files expects row lengths to be a multiple of 4 bytes. This changes the size you specified in header offset 34 and therefore the size in offset 2. Please refer to the following for details:
http://en.wikipedia.org/wiki/BMP_file_format
Related Part:
For file storage purposes, only the size of each row must be a multiple of 4 bytes while the file offset can be arbitrary
You can compare file by creating a 970x970 Red BMP file using MS Paint.

Java Graphics2D Path2D Simplify or call from separate class

I'm wondering if I can clean up my code somehow using a list or call it from another class because I have a lot of exact Path2D coordinates just cluttering my paintComponent.

{ Graphics2D g2=(Graphics2D)g;
super.paintComponent(g2);
//Background
Rectangle background = new Rectangle(0,0,getWidth(),getHeight());
Color skyBlue = new Color(135,206,235);
g2.setColor(skyBlue);
g2.fill (background);

Whatever you do I would
create the Path2D objects outside of the paintComponent() method.
add each Path2D object to an ArrayList
in the paintComponent() method you can iterate through the ArrayList to paint each Path2D
Or another approach is to just have a method that:
creates each Path2D object when the class is created
then you paint the Path2D object to a BufferedImage
now that you have a BufferedImage you can create an ImageIcon and Just use a JLabel in you app and you don't need the custom panel.

Heres 2 options I would consider for cleaning up the pathing.
Use SVG, one library I know is Batik found at: http://xmlgraphics.apache.org/batik/
Once I did a project where the paths I needed would be created in photoshop then exported to Illustrator. The file format was each action was line delineated, each line was space delineated and consisted of a set of points with the last entry the command name. Here was a sample input.
10 10 m
15 15 l
10 10 12 12 v
As you can see you just read the file, create your path and do an if test for the last letter on the line and use the appropriate command with for the points. Of course you can make up your own format or procedures but it sure was nice using photoshop for me :)
