Hi,
I intend to obtain the binary image. The intensity values of real image (varies from 0 to 4096) stored in the matrix, let's say 'h' . I tried to obtain the binarized images with the follwoing code, but I got some wierd image.. Do I need to play with the thresold ??
BW = imbinarize(h,'global');
imagesc(BW);

imagesc uses the current colormap. After you use it
colormap(gray(2))

Thanks for an reply, I tried this one. In fact, I switched to imshow (), but still I am not getting the expected image .. I have attached the real and binarized image for your refrence. .
