Hello I don t know if I am doing something wrong or not but when I do the following:

IplImage *testimage;
testimage = cvCreateImage(cvSize(10,10),IPL_DEPTH_8U,1);
cvThreshold(testimage,testimage,127,127,CV_THRESH_TRUNC);

everything works fine then when I try to use unsigned short values:

IplImage *testimage;
testimage = cvCreateImage(cvSize(10,10),IPL_DEPTH_16U,1);
cvThreshold(testimage,testimage,127,127,CV_THRESH_TRUNC);

my program crashes… I use opencv 2.4.2 I think this could maybe be a bug in opencv.
Somehow if I try the following:

IplImage *testimage;
testimage = cvCreateImage(cvSize(10,10),IPL_DEPTH_16S,1);
cvThreshold(testimage,testimage,127,127,CV_THRESH_TRUNC);

it doesn t crash anymore

    It is not crashing. It is throwing an exception and since you are not catching it, your program is aborting.
    OpenCV Thresholding does not support 16U.

    The supported ones are: 8U, 16S and 32F
