Problems solved by technology

[0003] Due to the constraints of hardware conditions and the level of endoscopists, there are phenomena such as uneven illumination, blurred images, and weak contrast between microvessels and image background in the magnified imaging of gastric mucosa staining, which makes it impossible to perform well on the magnified images of gastric mucosa staining. Vascular segmentation, thus affecting the judgment of follow-up physicians and causing misdiagnosis

Abstract

The invention provides a blood vessel segmentation method, a terminal and a computer readable storage medium. The method comprises the steps: obtaining a dark channel of an original image obtained after gastric mucosa is dyed and amplified in advance, and obtaining a first gastric mucosa image; performing first image quality enhancement processing on the original image based on the first gastric mucosa image to obtain a second gastric mucosa image; performing blood vessel segmentation on the second gastric mucosa image to obtain a first blood vessel segmentation image; and repairing the first blood vessel segmentation image to obtain a target blood vessel segmentation image. According to the method, the requirement for the quality of a gastroscope image is not high, the method is not sensitive to the image brightness and the image contrast, a good segmentation effect is achieved, further, the segmented image is repaired, the accuracy of the image is improved, and the situation that a doctor misdiagnoses due to the image quality problem is avoided.

Description

technical field [0001] The present application relates to the field of medical assistance technology, and in particular to a blood vessel segmentation method, a terminal, and a computer-readable storage medium. Background technique [0002] Microvessel analysis of gastric mucosal staining and magnification imaging plays an important role in the diagnosis of early gastric cancer: Yao Kenfumi pointed out in the VS typing theory that there are irregular microvessels with demarcation lines in early gastric cancer; Yagi Kazuyoshi in mesh-loop It is pointed out in the theory that the microvessels of differentiated gastric cancer can be divided into network structure and ring structure under the state of staining amplification, and the vascular morphology of undifferentiated gastric cancer can be divided into Lemon boat shape, wave shape and spiral shape. The analysis of microvessels in the above theory is a qualitative analysis based on personal experience. If quantitative analysi...
