Problems solved by technology

At present, for the processing of vein images, most of the vein images are enhanced in a single scale space to achieve better observation effects, such as histogram equalization or image segmentation of vein parts, etc. However, due to the different diameters and thicknesses of different veins, , the effect of image enhancement is not good, and the processed image has problems such as blurred vein outline, rough vein edge, a large amount of non-vein noise and serious distortion in the image

Abstract

The present application discloses an image enhancement method, an image enhancement device, and a computer-readable storage medium. The method includes: processing a grayscale image to obtain a first processed image; using a preset initial scale factor as the current scale factor; based on the current The scale factor processes the first processed image to construct the current filter; uses the current filter to filter the first processed image to generate the first filtered image; if the current scale factor is not greater than the maximum scale factor, the current scale factor and the preset scale The sum of the steps is used as the current scale factor, and returns to the step of processing the first processed image based on the current scale factor until the current scale factor is greater than the maximum scale factor; the first filtered image is processed to obtain an enhanced image. Through the above method, the present application can effectively improve the effect of image enhancement.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image enhancement method, an image enhancement device and a computer-readable storage medium. Background technique [0002] In scenarios such as elbow vein injection, blood collection, or puncture, it is necessary to accurately and quickly determine the location of the vein. It is difficult for a large number of patients to observe the vein during this process. A series of vein observation equipment has been derived from this. The mainstream vein observation equipment currently on the market Observation equipment includes: vein imager and vein projector. The vein imager can collect images of veins on the body surface, and display them on the display screen after the images are enhanced, which is convenient for treatment and diagnosis; the vein projector processes the collected vein images , and project it onto the body surface for more intuitive observation....
