METHOD AND APPARATUS FOR GENERATING SHARP IMAGE BASED ON BLURRY IMAGE

摘要

The present invention shows a method for generating a sharp image based on a faint image. The method includes obtaining a convolution kernel of a pixel value of a pixel and a fuzzy image; Determining a deconvolution kernel of the blurry image based on a predetermined image gradient operator and the convolution kernel; Determining a pixel value of a pixel of a clear image based on the deconvolution kernel and the pixel value of the pixel of the blurry image; And generating a sharp image based on the pixel value of the pixel of the sharp image. The deconvolution kernel of the embodiment of the present invention is determined based on the gradient operator and the convolution kernel. In other words, the deconvolution kernel introduces a gradient operator as a formulation constraint factor, and these gradient operators prevent noise from affecting the image reconstruction process and improve the quality of the reconstructed sharp image.
