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 ratio and the resolution ratio of the medical image cannot be effectively enhanced in the prior art. The image processing method comprises the steps of obtaining a first image and a second image, wherein the first image and the second image are the same; performing histogram equalization processing on the first image; performing two-dimensional discrete wavelet transformation on the processed first image to obtain a first high-frequency subgraph anda first low-frequency subgraph; performing two-dimensional discrete wavelet transformation on the second image to obtain a second high-frequency subgraph and a second low-frequency subgraph; carryingout passivation fuzzy processing on the second high-frequency subgraph; and carrying out image fusion on the first high-frequency sub-image, the first low-frequency sub-image, the processed second high-frequency sub-image and the processed second low-frequency sub-image based on wavelet transformation. The method can be widely applied to the scene of processing the medical image.

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...
