Abstract：Objective A remote partial image transmission algorithm is designed to solve the problem of transmission delay caused by
huge amount of image data. Methods The surgical terminal detected the region of interest (ROI), and removed the fuzzy area, bright
area and dark area in the endoscopic video，then obtained a mask frame containing only the information of interest丨 The remote
transmission used a modular method to realize video encoding, code stream decoding and network interactive programming. The
operation terminal used the Criminisi algorithm to repair the ROI area to improve video quality. Results Only the ROI of endoscopic
images was transmitted, which could reduce the data volume by 8.3% on average. The Criminisi algorithm could repair the mask
image, and the whole image optimization process took about 93 ms. Conclusion The remote partial transmission algorithm has the
characteristics of low delay, high speediness and high efficiency. It can successfully complete the remote diagnosis and treatment of
digestive endoscopy and effectively improve the medical level in remote areas.
