Abstract:
PURPOSE: A non-uniform motion blur removal method for a large input image based on a tile unit and an apparatus thereof are provided to overcome the limit of a storage space required to process a large image by removing blurs after dividing the large input image into local areas comprising tile units. CONSTITUTION: A non-uniform motion blur removal apparatus divides an input image into a plurality of tile units (201). The non-uniform motion blur removal apparatus selects one of a plurality of the tile units (203). The non-uniform motion blur removal apparatus estimates non-uniform motion blur information about the selected tile unit by performing image matching (205). The non-uniform motion blur removal apparatus obtains a latent image of each tile units by removing non-uniform motion blurs based on the estimated non-uniform motion blur information (209). The non-uniform motion blur removal apparatus restores the input image by using the latent image (211).

PURPOSE: A non-uniform motion blur removal method using multi-frames comprising a blurred image and an image with noise and an apparatus thereof are provided to accurately and quickly estimate a clearer image by estimating non-uniform motion blur information about a blurred image using the multi-frames. CONSTITUTION: A non-uniform motion blur removal apparatus receives multi frames (201). The non-uniform motion blur removal apparatus processes a blurred image and an image with noise through image brightness matching using a histogram matching method (203). The non-uniform motion blur removal apparatus estimates non-uniform motion blur information about the generated blurred image (205). The non-uniform motion blur removal apparatus obtains a latent image which is produced by removing the non-uniform motion blur from the multi-frames base on the estimated non-uniform motion blur information (207).

PURPOSE: A method and an apparatus for estimating a non-uniform motion blur robustly are provided to estimate homographies in an input image by increasing the number of estimated homographies step by step, thereby improving accuracy and stability of information about the non-uniform motion blur.
