Problems solved by technology

[0007] Now there is an image processing technology called background blur, that is, by defocusing the distant view behind the subject, weakening the details of the distant view, so that the near view and the distant view present a sense of hierarchy to achieve visual impact. And effectively highlight the object of interest, but this technology do

Abstract

The invention provides an image center enhancement processing method for simulating human eyes, which highlights an image center area and has stronger visual impact. According to the method, a non-linear function is used for modulating a resampling rate, resampling processing is carried out on an image, more pixels are distributed to a central area of the image, so that the middle area of the image is highlighted, edge details are weakened, a non-linear optic nerve distribution mechanism of human eyes is simulated, and a picture presents a feeling closer to the human eyes.

Description

technical field [0001] The present invention relates to image processing. Background technique [0002] Humans obtain image information in nature through their eyes, but because the human eyes are composed of a series of special structures such as eyeballs, lenses, and central fovea, the information received by the human brain is inverted, distorted, and nonlinear. Thanks to the powerful human brain, the image acquired by the human eye is processed by the brain, its direction and image distortion are corrected, and the blind spot area of ​​​​the human eye is brain supplemented. When the human brain processes visual information, it often prioritizes the middle area of ​​the field of view. This is because the middle area is often the area that people want to focus on. Therefore, in visual processing, the middle area will be properly emphasized (for example, the center of the field of view is allocate more neurons), while the edge region of the image is weakened to a certain e...
