Abstract

The invention relates to the technical field of image processing, in particular to an image resolution reconstruction method, which comprises the following steps that pixels of an original image are projected into an amplified image in equal proportion, and values are assigned to blank pixels inserted into reference pixels according to the projected reference pixels; the assignment of the blank pixel can be closer to the value of the reference pixel closer to the blank pixel, so that the overall sharpness of the image is higher, and excessive blurring of the image after resolution reconstruction is avoided; meanwhile, the edge position is assigned in an exponential level mode, so that the RGB value of the blank pixel at the edge position can be quickly converged, the value of the blank pixel at the edge position can be closer to the value of the reference pixel at the edge, and edge blurring and sawteeth are avoided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image resolution reconstruction method. Background technique [0002] Image resolution refers to the ability of the imaging system to distinguish image details, and it is one of the important indicators to measure image quality. High-resolution images can provide rich detailed information. With the continuous progress of economy, technology, and civilization, the demand for high-resolution images is increasing in various fields such as medicine, security, and entertainment. For example, doctors hope to identify lesions through high-resolution CT or B-ultrasound images; public security departments hope to identify suspects’ identities or vehicle information through high-resolution surveillance images; Visual effect. [0003] The most direct way to improve the resolution is to increase the hardware resolution of the digital image acquisition system, mainly from two as...
