Abstract: The following paper proposes a vector based technique of image processing for converting color images to grayscale images. The three base color channels of red, green and blue are assumed to form the three vector axes of a 3-dimensional vector space with every color having an equal influence at the resultant vector of the three axes. The results of the proposed algorithm are compared with those from the averaging technique or the same.
