Abstract: Image processing technology has a very important application in power grid,and image segmentation is an important part of image processing technology.In this paper,an interactive power grid equipment image segmentation algorithm integrating target detection is proposed.Based on the traditional GrabCut interactive segmentation algorithm,the detection calibration box obtained by target detection is used to replace the initialization box selected by the user.On the target detection algorithm,the fastest and lightest YOLO-Fastest algorithm known to be open source is adopted,which can overcome the difficulty of insufficient computing power of many equipment.The applicability of the algorithm is wider.Experimental results show that compared with the traditional interactive segmentation algorithm,this algorithm has shorter execution time,fewer interaction times,and has good stability.
