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);

在 MATLAB Online 中打开

imagesc uses the current colormap. After you use it

colormap(gray(2))
