TLDR
Wang et al. as discussed by the authors proposed a gastric ulcer model evaluation method based on grey-scale image analysis, which comprises three steps, which are image collection, image conversion, and data processing and ulcer index calculation.Abstract:
The invention discloses a gastric ulcer model evaluation method based on grey-scale image analysis The method comprises three steps, which are image collection, image conversion, and data processing and ulcer index calculation In the image collection step, a sample is placed in a dark box with a fixed volume and a fixed light source; and color (RPG) images are collected by shooting by using image collection tools such as a digital camera In the image conversion step, analysis software such as ImageJ is adopted, and the collected color images are subject to grey-scale image conversion, gastric mucosa region image selection and pixel statistics, and gastric ulcer region image selection and pixel statistics In the data processing and ulcer index calculation step, in units of pixel points, the percentage of the area of the gastric ulcer region in the mucous membrane gross area is calculated, and is adopted as the ulcer index for evaluating the gastric ulcer model With the method, rat/mice experimental gastric ulcer models can be accurately evaluated The method is also suitable for other image analysis and statistics with images as targetsread more
