Tracking objects using javaCV

Question

I am trying to track faces using Camshift in JavaCV. I have found Open CV equivalent at:

https://gist.github.com/231696

I have been successfully able to convert much part of the code, but struggling to figure out the equivalent of the following in JavaCV. Any help will be really appreciated.

TrackedObj* obj;

if((obj = malloc(sizeof *obj)) != NULL) {

obj->hsv  = cvCreateImage(cvGetSize(image), 8, 3);
obj->mask = cvCreateImage(cvGetSize(image), 8, 1);
obj->hue  = cvCreateImage(cvGetSize(image), 8, 1);
obj->prob = cvCreateImage(cvGetSize(image), 8, 1);
}

Answer 1

Well, we can define a class similar to the struct TrackedObj like this:

class TrackedObj {
    IplImage hsv;
    IplImage hue;
    IplImage mask;
    IplImage prob;
    CvHistogram hist;
    CvRect prev_rect;
    CvBox2D curr_box;
} 

And we can translate the bit of code you point out in a very similar fashion like this:

TrackedObj obj = new TrackedObj();
obj.hsv  = cvCreateImage(cvGetSize(image), 8, 3);
obj.mask = cvCreateImage(cvGetSize(image), 8, 1);
obj.hue  = cvCreateImage(cvGetSize(image), 8, 1);
obj.prob = cvCreateImage(cvGetSize(image), 8, 1);
