A novel approach for fruit shape detection in RGB space was proposed,which was based on fast level set and Chan-Vese model named as Modified Chan-Vese model(MCV) . This new algorithm is fast and suitable for fruit sorting because it does not need re-initializing. MCV has three advantages compared to the traditional methods. First,it provides a unified frame-work for detecting fruit shape boundary,and does not need any preprocessing even though the raw image is noisy or blurred. Second,if the fruit has different colors at the edges,it can detect perfect boundary. Third,it processed directly in color space without any transformations that may lose much information. The proposed method has been applied to fruit shape detection with promising result. 展开更多

Multiple primary carcinoma which is the same organ of the same patient or multiple organs, tissues has occurred two or more than two kinds of the primary malignant tumor. All cancer at the same time or 6 months from diagnosis is called simultaneous multiple primary carcinoma. In this case the patient suffering from cancer including rectal cancer, colon cancer and appendix gastrointestinal stromal tumor(GIST) three primary carcinoma, is simultaneous multiple primary carcinoma and it's extremely rare on the clinical cases. This report address that the incidence of the patient with operation and pathological diagnosis. 展开更多
