Patch-based Image Colorization

Abstract : Image colorization consists in adding colors to grayscale images. Two approaches are mainly used: the first one consists in using manually pre-defined color inputs while the second consider an entire colored image as color example to transfer. The work presented here is in the second category. Indeed, we propose a simple patch-based image colorization based on an input image as a color example. First, we introduce a general colorization model in which many methods of literature can be casted within this framework. Second, we describe our method which is based on patch descriptors of luminance features and a color prediction model with a general distance selection strategy. We also propose to perform a Total Variation (TV) regularization on the colorized image to ensure the spatial color coherency of the final result. Finally, experiments show the potential- ity of our proposition in order to automatically colorize grayscale images. Comparisons with methods from the literature are also provided
