Extremely Low Light Video Enhancement along with No-Reference Video Quality Measurements

Low light video enhancement is a challenge many researchers have been facing. Low illumination is the cause for low light videos. Noise present in the videos adds to the low quality of the low light video. So to improve the quality of videos the noise present in the videos has to be suppressed before enhancement is attempted. This paper addresses Kalman filter to suppress the noise from the extremely low light video. Though entire noise could not be suppressed by this technique a Non local means filter helps to remove the remaining noise after amplification. The Gray World technique is used for amplification. After removing the noise by using NLM filter image enhancement of extremely low light video is carried out.
