In this work, a novel approach for restoration of Color faded images is presented. A Uniform fading model is assumed. The algorithm comprises of matching the blocks in the image with some predefined reference blocks. These reference blocks are used to represent the true color of objects. The Correlation Coefficient is used as a measure for similarity matching. The threshold used for determining the matching is chosen adaptively from the image itself. A fade detection algorithm is proposed for distinguishing color faded images from the images with true cast. The algorithm has been tested and validated over a number of image sequences.
