Video is a changing image, it moves over time. Neat Video is a digital filter designed to reduce visible noise and grain is seen from perhaps even, DSLRs, TV-tuners, and movie cameras VHS or movie. The answer lies on the very nature of video. How can we know that bright spot on the beach is caused by a sand grain or a noisy pixel? What’s different between a video of a sand beach and pure noise? They both have small detail, the pattern is random in most cases and it affects all of the channels. Our goal is to find a criteria which helps us to separate the damage pixels. A median filter is more subtle, but it will only work when the noise is very visible and very small. A blur filter will remove all the noise, but it will also destroy the rest of the image. You could try to look for small pixels which differ from the surrounding patterns, you could try to smooth the hole images keeping the borders intact, you could apply complex statistical models which decide if a pixel is susceptible to be noisy, etc.īut we do not want to affect the detail and textures of the image. There are many ways to decide how much noise a pixel has.
