Embodiment 1

[0024] Append figure 1 As shown, the embodiment of the present invention provides an image enhancement method, which is described in detail with the enhancement of medical images, mainly including the following steps:

[0025] S1, the image to be processed from the RGB color space to YUV color space, obtain brightness information and chrominance information;

[0026] The image to be processed here is a medical image, but it is also possible to apply to palm-grade images, pupil images, face images, natural images, etc., not limited to medical images, first enter the medical RGB image to be processed, and treat images to fix Frequency sampling;

[0027] The image to be processed from the RGB color space to the YUV color space, the transform formula is as follows:

[0028] (1)

[0029] In the YUV color space, the brightness information y, and the two chrominance information u, V is completely separated. The value range of each parameter is: R is a red coefficient: 0-255; g is a gre...

Embodiment 2

[0072] Based on the above-described embodiments, the embodiment of the present invention also provides an image enhancement system, including a memory and a processor, the memory stores an image enhancement program, the processor performs the above image enhancement when running the image enhancement program The step of the method embodiment.

Abstract

The invention discloses an image enhancement method and system, wherein the method includes: first transforming the medical image from the RGB color space to the YUV color space to obtain the brightness component, and calculating an improved image enhancement template based on G-L fractional differential , and then use the fixed-order enhancement template and the adaptive-order enhancement template to perform the first and second image enhancement on the brightness of the image respectively, and perform image fusion on the results of the two image enhancements to obtain a new brightness component; finally, The new luminance component is combined with the original chrominance information to obtain a new YUV color image, which is then converted to RGB color space to obtain the final enhanced medical image. Solve the problem of unclear texture details in the prior art, enhance texture details, and improve image quality.

Description

Technical field [0001] The present invention relates to the field of image processing, and is specifically an image enhancement method and a system. Background technique [0002] In recent years, with the development of computer technology, imaging technology is widely used to modern medicine, such as nuclear magnetic resonance technology, computer fault scanning techniques, etc., these medical imaging technologies provide favorable conditions for doctors. However, the medical image will be affected by noise during the formation process, resulting in the characteristics of the medical image of the shooting, which makes the doctor difficult to accurately obtain critical information with the naked eye, resulting in a misproduction or misunderstanding. Therefore, it is very important to enhance the medical image to have a very important application value. [0003] At present, the commonly used medical image texture structure enhancement method can mainly be divided into sharpening, ...
