Method and apparatus for extracting target image

Abstract

The invention provides a method and apparatus for extracting a target image, and relates to the technical field of image processing. The method comprises the steps of binarizing an infrared grayscale image to be processed by a preset way to obtain a binarized image; retaining the largest white communication region in the binarized image to obtain a first image containing the largest white communication region; retaining a plurality of black communication regions conforming to a preset condition in the first image to obtain a second image containing the plurality of black communication regions; and superimposing the infrared grayscale image and the second image to obtain a target grayscale image in which a target image is located in a region corresponding to the largest white communication region and background images located in regions corresponding to the black communication regions. The technical problem of interference of the background image in the infrared medical image with the target image is solved, and the technical effect of only retaining the target image while the background images in the infrared grayscale image are accurately, clearly and quickly eliminated, is achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for extracting a target image. Background technique [0002] Thermography, also known as temperature difference photography, is a modern physical detection technology that uses the principle of infrared radiation photography to study the distribution of body surface temperature. Compared with precise anatomy, thermal imaging systems have unique characteristics in reflecting changes in human physiology and metabolic processes. With the development of image processing and medical technology, medical infrared images will play an important role in the fields of TCM constitution identification, disease diagnosis and health assessment. [0003] At present, most image background processing technologies can only visually distinguish the target image from the background image. If you want to eliminate the background interference in infrared medical images and...

Problems solved by technology

[0003] At present, most image background processing technologies can only visually distinguish the target image from the background image. If you want to eliminate the background interference in infrared medical images and accurately identify the target image, you need to rely on experienced doctors for interpretation and evaluation, or Subsequent automatic analysis and identification and other intelligent processing, the degree of intelligence is limited
