The rapid extraction and analysis of Minimally invasive surgery image features,can make the computer have image re- al-time recognition ability,and improve the success rate of surgery.The common edge and corner point features,this paper analyzes the edge and corner combining feature extraction method,With Mitral Valve Chordae Repair Minimally invasive surgery image as an example,the commonly used several kinds edge algorithm and improved Canny algorithm are ana- lyzed and compared,and the use of improved Canny operator the relatively complete detection edge information.Using the SIFT algorithm...
