Problems solved by technology
However, the above-mentioned homomorphic filtering method based on the illumination-reflection model needs to configure different illumination models for different types of pictures. Before performing image enhancement processing on the image, it is necessary to continuously test to obtain the parameters of the high and low frequency of the segmented image, and then configure the illumination model. The augmentation algorithm is less robust in terms of parameter selection
In addition, the above method does not fully consider the local characteristics of the image in the spatial domain, and when some pixels of the image are enhanced, another part of the pixels is over-enhanced, resulting in poor quality of the enhanced image obtained by image enhancement.

Description
technical field [0001] The present invention relates to the technical field of computer applications, in particular to an image processing method, device and terminal equipment. Background technique [0002] As a means of transmitting and obtaining information, images can provide more intuitive information than text or sound. As a low-level processing link of image processing, image enhancement aims to improve the quality of the image itself, improve the visual effect of the image to be more suitable for human observation or machine analysis and recognition, and then obtain more useful information from the image. Traditional image enhancement methods can include a homomorphic filtering method based on the illumination-reflection model, that is, the original image is expressed as the product of the illumination component and the reflection component, the illumination component of the image represents the low-frequency spectrum part of the image, and the reflection component o...
