2D Noise Reduction (2DNR)
Signal distortion, or “noise”, is an unavoidable by-product of amplifiers. Even when working at optimal level, digital amplifiers, whether used in audio or video applications, create some noise. Video “noise” can take the form of “static”, fog, speckles, haze, fuzz, transparent color bocks and other visual artifacts that make your images look less than crystal clear. Therefore noise reduction is an important aspect of surveillance camera design and selection. It becomes even more important as display technology advances and gives people the ability to view higher and higher resolution images.
The 2D Noise Reduction block performs 2D spatial noise reduction on the image. The 2D noise filter operates on a 5 x 5 filtering window for each color plane.
