Performance Analysis of Kekre's Median Fast Search, Kekre's Centroid Fast Search and Exhaustive Search Used for Colouring a Greyscale Image
Abstract—While there exist various techniques that can be used to colour a greyscale image, such as those described in [1],[2], [3] and [4], in this paper we focus on one such technique that can be used with various colour spaces such as RGB, LUV, YCgCb, YCbCr, YUV, XYZ, and YIQ. This technique is described in detail in [4]. In this paper we analyse the performance of Kekre’s Median Fast Search, Kekre’s Centroid Fast Search and Exhaustive Search algorithms in the greyscale colouring process with respect to time taken forcolourization and quality of the coloured image.
Index Terms—colour transfer, colour palette, colour spaces, pixel windows, colourization.
