Outline of Final Research Achievements

We introduced the restoration algorithm for the high dynamic range image denoising. We proposed a new weighting strategy for integrating multiple images, which is capable of reducing quantization error and sensor noises, and then we have examined the validity of the algorithm. The second approach is the development of image integration for a flash/no-flash image pair, in which we formulate the integration problem as a convex optimization problem. Our method has a great advantage that it can handle even misaligned image pairs. Moreover we proposed an intrinsic image decomposition algorithm that can reduce the change of saturation when tone-mapping the image.
