Re: [ros-users] cvBridge + opencv memory leak problem

Hello Radu,

I'm well aware of using cvReleaseImage..
Memory leak happens even if I use a single function on IplImage converted
from sensor_msgs.
Here's my callback function to illustrate. Usage of cvCopy here introduces
memory blowup problem.

void callback(const sensor_msgs::CameraInfo::ConstPtr& info,
                const sensor_msgs::ImageConstPtr& left,
                const stereo_msgs::DisparityImageConstPtr& disparity_msg)
    {

    

        im_left = left_bridge.imgMsgToCv(left, "passthrough");

        disp_bridge.fromImage(disparity_msg->image, "passthrough");
        dispImg = disp_bridge.toIpl();    

        

        cvShowImage("left", im_left);

        IplImage* test = NULL;
        test = cvCreateImage(cvGetSize(dispImg), dispImg->depth, 1);
        cvCopy(dispImg, test);
        cvShowImage("disp", test);
       }

Also, I'm not supposed to deallocate any IplImages that are converted from
sensor_msgs as described in cvBridge tutorial.
Is there a way to use opencv functions on IplImages and not use cv::Mat ?
