Detection of view-disturbing Noise by using Vertical Clustering in Spatio-Temporal Image

Abstract

Recently, monitoring cameras are widely prevalent . But if we install them outside, sometimes raindrops or mud stick to their lens protecting glass and they appear as a noise in photograph .In this research, we propose a method that can remove noises better than conventional method. In conventional method, we take photographs while turning the camera and detect noises by considering the relationship between angles of photographing and objects in the images. But in this method, if the luminance of the objects and noises are so close, we can t detect noises exactly. So we solve the problem by using color information and clustering.
