Apparatus and method for enhancing image based on retinex using general dictionary

摘要

Retinex-based image restoration apparatus and method using a general dictionary according to a preferred embodiment of the present invention is a general dictionary (based on convolution sparse coding (CSC) and singular value decomposition (SVD)) general dictionary) and reconstructing the reflectance of the image using the general dictionary to restore the image, so that the image can be restored using the general dictionary continuously without re-learning in the dictionary, thereby improving the computational efficiency. You can save memory.
