摘要： Method and apparatuses for correcting vignetting effects of an image are disclosed. A method for vignetting correction of an image according to an exemplary embodiment of the present disclosure may comprise receiving a two-dimensional image; calculating a radial bright channel representing intensity of the two-dimensional image; estimating a vignetting function of the two-dimensional image having similarity to the calculated radial bright channel; and correcting the vignetting effects of the two-dimensional image by using the estimated vignetting function.

摘要： Disclosed are an image processing apparatus and an image processing method. The image processing method performed in the image processing apparatus comprises receiving a blurred image; generating an intermediate image from the blurred image, the intermediate image including artifacts with less sensitivity to changes in a blur kernel than the blurred image; and generating a first corrected image by removing the artifacts of the intermediate image using an artifact removal model. Therefore, it is made possible to learn how to remove artifacts of the intermediate image without the image processing apparatus learning a direct deconvolution method.

摘要： Disclosed is a method and device for filtering texture, using a patch shift. A patch-based texture filtering method for removing texture from an image comprises the steps of: distinguishing a structure edge from patches for each pixel of an input image; and performing a patch shift for the patches of each pixel, on the basis of structure edge information of each of the patches to select a representative patch of each pixel. Accordingly, the method can generate a result image in which texture has been automatically and completely removed from a piece of the input image.
