Research on removal technology of snowflakes in video images

摘要

Using improved K-means clustering method to remove snowflakes in video images got in snowy day is put forward. According to the brightness changes of the image, we clustering estimate brightness changes of all the pixels in the image by using background brightness values instead of the brightness values of the snowflakes to achieve the goal of removing snowflakes. The results of experiment show that the processing effect of the method is very obvious for light snow and heavy snow, and even storm snow. It can get good results.
