Problems solved by technology

[0004] However, in the existing image beautification algorithm based on curve adjustment, the blur radius used in the Gaussian blur processing is relatively large, which leads to a large amount of system resources when the entire algorithm is running, and thus requires high performance of the device, so that mobile devices, etc. Equipment with poor performance cannot complete real-time processing of images

Abstract

The embodiment of the invention discloses an image processing method and an image processing device. The method comprises the steps of separating a luminance component and a chrominance component of an original image, and obtaining an original brightness image and an original chrominance image; based on the fast filtering algorithm, performing filtering treatment on the original brightness image to obtain a first brightness image; performing curve adjustment on the original brightness image to obtain a second brightness image; based on the alpha fusion algorithm and the first brightness image,performing image fusion on the original brightness image and the second brightness image to obtain a target brightness image; obtaining a target image based on the target brightness image and the original chrominance image. By applying the scheme provided by the embodiment of the invention, during the image processing operation, on the premise that the processing effect is ensured, system resources occupied by the image processing algorithm can be reduced. Compared with the prior art, the image processing speed is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to an image processing method and device. Background technique [0002] Image processing refers to the technique of analyzing images with a computer to achieve the desired results. Image beautification processing is a common image processing method, which refers to an image processing method that uses a computer to process image information to meet human visual psychology or application needs, such as face beautification. With the rapid development of computer technology, image beautification processing is also constantly developing to meet people's needs. [0003] In the prior art, an image beautification algorithm based on curve adjustment is a commonly used image beautification processing method. Through this algorithm, the brightness of the darker defect areas in the image can be appropriately adjusted, while the contrast of the original image can also be preserv...
