Image processing method and apparatus

摘要

Embodiments of the present invention provide an image processing method and apparatus, where the image processing method includes: performing image magnification processing on a low-resolution image to obtain an initial high-resolution image; selecting a central similar block corresponding to a first pixel from the initial high-resolution image; selecting a search block corresponding to the first pixel from the low-resolution image, and determining each similar block in the search block, where the central similar block and the search block have a same block size; and determining a pixel value of the first pixel according to the central similar block and each similar block in the search block. By using technical solutions in the embodiments of the present invention, calculation complexity and an occupied memory resource can be effectively reduced.

主权项

1. An image processing method implemented by an image processing apparatus, the method comprising:
obtaining, an initial high-resolution image from a low-resolution image through image magnification processing; selecting, a central similar block from the initial high-resolution image, wherein the central similar block is associated with a pixel selected from the low-resolution image; determining a direction of a texture of a neighborhood range of the pixel in the low-resolution image; upon the determination, selecting, a search block from the low-resolution image associated with the pixel based on the determined direction; wherein the central similar block and the search block have a same block size; and determining, by the image processing apparatus, a pixel value of the pixel according to the central similar block and the search block.
