Problems solved by technology

The patient swallows the capsule with water like taking medicine, and it wriggles with the gastrointestinal muscles, records the pathological images in the digestive tract through the built-in micro camera, and displays the images to the doctor to provide a basis for his diagnosis, but because the capsule endoscope Relying on intestinal peristalsis in the body, the obtained images are often blurred, which may lead to unclear images of pathological areas and no way to accurately diagnose. For the problem that capsule endoscopic images are difficult to accurately identify, there is currently no special identification method. Most of them are identified by the naked eye of doctors. With the denoising and enhancement of images, the accuracy of identification can be improved to a certain extent, but the workload is huge, and manual identification is difficult to avoid false detection and missed detection, which brings great harm to the diagnosis of diseases. to a certain degree of difficulty

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to figure 1 As shown, it is a working flow chart of a preferred embodiment of the wireless capsule endoscope image recognition method of the present invention.

[0019] Step S401, acquiring an image of the patient's digestive tract. Specifically, the patient's digestive tract is photographed through the wireless capsule endoscope to obtain images of the patient's digestive tract.

[0020] Step S402, performing denoising and enhancement pre-processing on the acquired image to prepare for later processing and screening. Specifically, denoising processing and enhancement processing are respectively performed on the acquired image, so as to improve the recognition degree of the image.

[0021] In step S403, a graph of missing items in HSV space is made on the above-mentioned preprocessed image, and a threshold is set. In ...

Abstract

The invention relates to a method for identifying capsule endoscope images. The method comprises the following steps that digestive tract images of patients are obtained; the obtained images are preprocessed; a lacuna curve chart under HSV space is drawn for the preprocessed images, and a threshold value is set; the images are screened and classified through the set threshold value. The invention further relates to a system for identifying the capsule endoscope images. According to the method and system, the workload of a doctor can be reduced, and identifying accuracy is improved.

Description

technical field [0001] The invention relates to a wireless capsule endoscope image recognition method and system. Background technique [0002] Gastrointestinal mucosal disease and the further alimentary canal cancer caused by it are one of the biggest killers of national health (accounting for about 60-70% of the incidence of all malignant tumors in my country). According to statistics from the American Cancer Society, early detection and diagnosis of neoplasia metastasis is a key factor in reducing the mortality rate of digestive tract cancer (especially bowel cancer): if bowel cancer patients If the mutation is detected in the early stage and treated, the five-year survival rate can usually exceed 90%. If it is not detected in the early stage but allowed to develop to the middle and late stage, the five-year survival rate of the patient is only less than 10%. Traditionally, doctors need to insert a fiberoptic endoscope into the patient's body to observe the inside of the...
