Objective     To study on how to remove the background in the digital images of visible human body.      Methods     After removing most of the background with standardized thresholds segmentation

we did identification

connection and noise-removing work against the edge around the target verge

and then the results of these two methods were combined to get the final image.      Results     Complex segmentation technology based on edge and thresholds effectively removed the background in the image of human body.      Conclusion     Compared with other segmentation algorithm

the algorithm presented here has better practical effect.
