Image inpainting refers to the process of reconstructing the original image from a damaged one in a visually plausible way. We propose a new gradientbased algorithm for exemplar-based inpainting by making use of L1 norm. We implement the most time consuming step of the algorithm on the GPU and compare the serial execution timings against the parallel execution timings. The parallel implementation has an average speedup of 14 over the serial implementation. The results obtained from our approach are perceptually on par and in many cases better than the state-of-the-art approaches to date.
