Frequency Domain Directional Filtering Based Rain Streaks Removal from a Single Color Image

摘要

Bad weather conditions, such as rain or snow, degrade outdoor vision system performance. Rain removal from a single image has been investigated extensively. However, existing built rain streak models are greatly influenced by inaccurate parameter estimation or non-stationary background due to camera motions. In this paper, we propose a rain streak removal algorithm from a single color image based on frequency-domain directional filter. Experiment results demonstrate that the proposed algorithm can deal with rain steaks of any directions, and maintains more details than existing algorithms.
