This software adds artificial noise (equidistributed, normaldistributed, colour stains, echo signal) to video streams for testing, debugging, and comparison of denoising filters.
One of the most impressive features of this filter is how easy it is to customize the noise you're adding. For example, in the Settings dialogue box, you can choose the type of noise you want to generate. You'll also be able to specify the intensity of that noise for each color component, all while utilizing the YCrCb color space to ensure maximum customization.
It's also worth mentioning that this software allows you to change the individual noise parameters for certain noise types, further increasing your customization options. All in all, if you're looking for a top-of-the-line filter to add artificial noise to your video stream, this one is definitely worth considering.
Version 2.1: Echo signal distortion is added. User interface became more convenient.
