Abstract

The invention discloses an image processing method and device, relates to the field of medical images, and can solve the problem that the contrast and resolution of medical images cannot be effectively enhanced in the prior art. The image processing method of the present invention includes: acquiring a first image and a second image, the first image and the second image being the same; performing a histogram equalization process on the first image; performing a histogram equalization process on the processed first image Two-dimensional discrete wavelet transform to obtain a first high-frequency sub-image and a first low-frequency sub-image; performing two-dimensional discrete wavelet transform on the second image to obtain a second high-frequency sub-image and a second low-frequency sub-image; Perform passivation and fuzzy processing on the second high-frequency sub-image; based on wavelet transform, the first high-frequency sub-image, the first low-frequency sub-image, the processed second high-frequency sub-image and the second low-frequency sub-image Perform image fusion. The present invention can be widely applied in the scene of processing medical images.

Description

technical field [0001] The invention relates to the field of medical images, in particular to an image processing method and device. Background technique [0002] Medical imaging refers to the technology and processing process of obtaining internal tissue images of the human body or a certain part of the human body in a non-invasive manner for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging system and medical image processing. Medical image processing refers to the further processing of the obtained images, the purpose of which is to restore the original image that is not clear enough, or to highlight certain feature information in the image. [0003] Medical imaging produces some noise interference during the imaging process, resulting in problems such as low contrast and low resolution of the image. Therefore, in medical image processing, image enhancement processing is first performed on th...
