摘要： The present invention provides a transfer learning based capsule endoscopic images classification system. The system removes the capsule endoscopic images with an average brightness value beyond the preset threshold, and removes the capsule endoscopic images without details based on image brightness standard deviation and image brightness gradient. The system also removes similar images from the capsule endoscopic images using optical flow method, classifies the capsule endoscopic images according to the corresponding anatomical structure, and obtains the classified capsule endoscopic images list arranged in chronological order. The system further determines and labels the position of the first image of each specific anatomical structure in the classified capsule endoscopic images list arranged in chronological order.

摘要： The present invention provides a capsule endoscopy image review and quality control system and control method thereof. The capsule endoscopy image review and quality control system include a capsule endoscopy data acquisition system and a local server in communication with the capsule endoscopy data acquisition system. The capsule endoscopy data acquisition system includes a capsule endoscope, an external magnetic field device for controlling movement and/or rotation of the capsule endoscope, and a controller in communication with the capsule endoscope and the external magnetic field device. The local server includes a digestive tract position identification module and a corresponding matching module for quality control process, wherein the corresponding matching module for quality control process and the digestive tract position identification module are in communication with the controller.
