Problems solved by technology

[0003] At present, the image processing method for processing microcirculation imaging on the market is to manually click and take the video when the lens shake is judged to be small or stable, and to intercept and analyze several single-frame images subjectively considered to be better in the recorded video, so the obtained The image has the following disadvantages: the captured image has a large error with the actual blood flow, the obtained blood vessel is discontinuous, the edge is not clear, and the complete path of the blood vessel cannot be confirmed; the intercepted picture lacks scientific data basis and relies entirely on human subjective judgment. low efficiency

Abstract

The invention relates to the technical field of medical image processing, in particular to a microcirculation image blood vessel path extraction method and device. The method comprises the following steps: continuously acquiring multiple frames of microcirculation images; extracting the brightness value and the gray scale gradient value of each frame of microcirculation image, wherein the brightness value is the brightness value of the highest brightness point of the microcirculation image; calculating the correlation degree between two adjacent frames of microcirculation images; selecting continuous multi-frame microcirculation images according to the brightness value, the gray scale gradient value and the correlation degree; and synthesizing the selected multi-frame microcirculation images to obtain a target image. The invention includes performing quality analysis on a brightness value and a gray gradient value of a microcirculation image, intuitively selecting a plurality of continuous frames of microcirculation images for two quantitative indexes of difference value analysis between two adjacent frames of microcirculation images, and synthesizing the continuous frames of microcirculation images into one frame of microcirculation image, wherein the blood vessel imaging in the synthesized microcirculation image is clear and continuous, and a relatively complete blood vessel path can be shown.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method and device for extracting blood vessel paths from microcirculation images. Background technique [0002] Microcirculation is the blood circulation between arterioles and venules in the vascular network. It is the place where blood exchanges substances with various tissue cells. It provides oxygen and nutrients for organs and tissues and discharges carbon dioxide and metabolic waste. It is an important unit in human blood circulation. one. [0003] At present, the image processing method for processing microcirculation imaging on the market is to manually click and take the video when the lens shake is judged to be small or stable, and to intercept and analyze several single-frame images subjectively considered to be better in the recorded video, so the obtained The image has the following disadvantages: the captured image has a large error with the actu...
