The research group under the leadership of Prof. Sudipta Mukhopadhyay at the Dept. of Electronics and Electrical Communication has received the FICCI Research & Development Award 2017 for their innovation "Real-Time Fog Removal from Videos & Real-Time Rain Removal from Videos".
The innovation ideas were submitted by Mr. R. Hariharan and Mr. Manish Kumar Sharma. This work is the accumulation of contributions of research and development by Dr. Abhishek Kumar Tripathi, Mr. Nishant Gaurav, Ms. Bhamidipati Sridevi, Ms. Ashwini R. Patil and Mr. Leuva Hardik P. in addition to R.Hariharan & Manish K Sharma.
The team developed algorithms for removing fog and rain from videos in real-time. The fog algorithm estimates the distance of the objects from the camera in the form of the depth map. The depth map is further refined using anisotropic diffusion to identify the clear boundaries of the object. Based on the refined depth the image is restored back to give cleaned images. This operation is performed on every frame of the video to generate a defogged video stream.
Probabilistic model-based temporal and Spatio-temporal rain removal algorithms are developed which are both effective in removing rain from rain-affected videos and are real-time in nature. It is based on the difference in the time evolution properties of that rain and non-rain pixels.
