'How to save an image which only display properly using imshow(grayImg,[])?
I am working on an image encryption project, so I first converts color image to gray and do the rest, after encryption I can see the image only using
imshow(grayImg,[])
Not by
imshow(grayImg)
but if I store the image with
imwrite(grayImg,outputFileName);
Then it isn't saving as expected or not as I saw when using imshow(grayImg,[]) Does anyone know what kind of error am I making?
