Efficient color-to-gray conversion for digital images in gradient domain


Color-to-gray conversion for digital color images is widely used in many applications. In this paper we propose an efficient gradient domain color-to-gray conversion algorithm depending on automatic optimization of parameters. A gradient field, defined with the luminance gradient and a modulated chromatic difference enhancement in CIELAB space, is created… (More)
