Abstract

The invention relates to an image enhancement technology in the field of computer vision in the field of artificial intelligence, and provides an image enhancement method and device. The invention relates to the field of artificial intelligence and computer vision. The method comprises the steps of adjusting the pixel values of a to-be-processed image are adjusted, K images are obtained, the pixelvalues of the K images are different, and K is a positive integer larger than 1; extracting local features of the K images; extracting global features of the to-be-processed image; and performing image enhancement processing on the to-be-processed image according to the global features and the local features to obtain an output image after image enhancement. The method is helpful for improving the effect of image quality enhancement processing.

Description

technical field [0001] The present application relates to the field of artificial intelligence, and more specifically, to an image enhancement method and device. Background technique [0002] Computer vision is an integral part of various intelligent / autonomous systems in various application fields such as manufacturing, inspection, document analysis, medical diagnosis, and military. What we need is the knowledge of the data and information of the subject being photographed. To put it figuratively, it is to install eyes (cameras / video cameras) and brains (algorithms) on computers to replace human eyes to identify, track and measure targets, so that computers can perceive the environment. Because perception can be thought of as extracting information from sensory signals, computer vision can also be thought of as the science of how to make artificial systems "perceive" from images or multidimensional data. In general, computer vision is to use various imaging systems to rep...
