Colorize higher-resolution image with lower-resolution one

Post by smaines »

I have two images, both scans: one is of a higher resolution, the other is better colored. Both are level. Is it somehow possible to use the lower-resolution image as an indication to ImageMagick of how I would like the higher-resolution image colorized?

Thanks in advance,

-SM

If the two images are registered together so that that overlay perfectly, then you can replace the hue and saturation channels of the high res image with those from the low resolution image. Alternately, if you are on Linux/Mac or Windows/Cygwin, you can try my histmatch script at the link below.
