MATLAB: How to convert the binarized image to the original gray image

binarized image to original image with gray valueconverted to gray imageImage Processing Toolbox

Dear all, Hello good morning,

Could you please share your experience how to convert the binarized image to the original image with gray vlaues? THank all.

You probably want

maskedImage = binaryImage .* originalImage;

Just OR them together:

finalBinaryImage = binaryImage1 | binaryImage2;

Let I be the m-by-n image, and let M be the m-by-n mask.

The new image, Inew, will be m-by-n and have zeros everywhere there is a zero in M and will be the grayscale value wherever M has a one.

Inew = I.*M;

If the image is RGB (i.e. I is m-by-n-by-3), then use the command

Inew = I.*repmat(M,[1,1,3]);
