Hi

You can use regionprops function on the 1st image to find the pixel location of the components using 'PixelList' property of the function. Use those pixel location in the 2nd image or create a matrix of zeros and assign the label value (as you have mentioned 2) at those location in the 2nd image/ in zeros matrix.
