Color transfer to greyscale images using texture spectrum

Color transfer between two images is one of the most common tasks in image processing. We present a method of pattern recognition to increase the successful possibility of transferring color from color image to greyscale image. A kind of texture descriptor, texture spectrum, plays an important role in the whole procedure. Source image retrieval is used and based on texture-spectrum similarity, which can find the most suitable color images in a color image database. Furthermore, texture-spectrum is also considered to sample color pixels reasonably. We found that the method works well and it can be successfully applied to a variety of images.
