Hi everyone,

I have trouble converting from Iplimage to Mat in java. Since OpenCV java API doesn't have ability to load video files, I utilized javacv to load video files. But then I need to convert Iplimage to Mat in order to use openCV to do face detection. What should I do to realize it?

Thanks for any help in advance!

This might not be of much help (just bits and pieces)... but someone posted the structure of IplImage here:

...and a fast function to convert Mat into java.awt.image.BufferedImage (which might resemble IplImage to some degree), can be found here:

( look for "public static BufferedImage matToBufferedImage(Mat bgr)" )

Basically, I would try to read the "imageData" field from IplImage structure and write it using "matrix.put(0, 0, data);" to the Mat object. If the dimensions and color palettes already match before trying this, it might succeed. But I've got no working method to try, since I can't get any IplImage structures on my system...
