Step 1: Make left half of right_side_image 0 intensity image (black). Also, make right half of left_side_image 0 intensity region. Webrgb2gray converts RGB values to grayscale values by forming a weighted sum of the R, G, and B components: * R + * G + * B. These are the same weights . IMOVERLAY_TOOL is an interface to graphically overlay one image on top of another and manipulate colormap, thresholding, and transparency. - Allows independent. The image is saved as grayscale unless you select a color map other than gray. Most common image formats are available; MAT-files are readable by MATLAB. I would like to overlay a semi-transparent colorimage over a grayscale image (colored fMRI activity map over a structural MRI image).
