Color2Gray: Salience-Preserving Color Removal


Visually important image features often disappear when color images are converted to grayscale. The algorithm Color2Gray presented in SIGGRAPH'05 paper "Color2Gray: Salience-Preserving Color Removal" reduces such losses by attempting to preserve the salient features of the color image.

We use FastColor2Gray, a modified version of the Color2Gray algorithm to produce different sequences of grayscale images from a single color image. The grayscale sequence is assembled to produce a new video that shows the original image in grayscale with a unique dynamic between the different gray tones.
