Study of the Preprocessing of Venous Images

Due to the design of intravenous imaging instruments and the rapid development of venipuncture robots, it is of great significe to study the high-quality venous image processing method. In this paper, a series of preprocessing of the venous image is carried out, and the development of venous image processing is briefly introduced. The process of vein image processing is mainly divided into three steps. The first step is to use the improved Otsu method for binarization. The second step is to use the selective median filter algorithm to filter. The third step is to refine the image with a fast parallel thinning algorithm. Experimental results show that the vein image processing effect is better.
