Hi
I would like to ask how to read the csv file in java environment? As the opencv docs said, we can use CvMldata read_csv(), it is available for both C/C++ and Python. However, I searched on the docs for java, there is not the equivalent.
Any suggestions, if you please?
I would like to add the database for my feature matching algorithm.
Thanks
File file = new File("infraImage_045_270.csv");
int rows = 240;
int cols = 320;
double buffRes[] = new double[cols*rows];
String line = "";
int k = 0;
try (BufferedReader br = new BufferedReader(new FileReader(file))) {
while ((line = br.readLine()) != null) {
String[] vpLine = line.split(",");
for(String s : vpLine) {
try {
buffRes[k] = Double.parseDouble(s);
}catch(NumberFormatException e) {
buffRes[k] = -Double.MAX_VALUE;
System.out.println("NAN");
}
k++;
}
}
}
Mat res = new Mat(rows, cols, 0);
res.put(0, 0, buffRes);
HighGui.imshow("Picture", res);
HighGui.waitKey(0);
System.exit(0);

"it is available for both C/C++ and Python" - where did you find that ? it does not seem to be wrapped for any scripting. i don't think, you can use it from java.
Well it seems so..
Do you have any suggestion on the alternative method?
The purpose is to construct a training set database so that I can apply the matching algorithm on the input.
