Recurrent blurring may be used to render frames of a virtual environment, where the radius
of a filter for a pixel is based on a number of successfully accumulated frames that cor …

A pixel filter has a filter module that performs a first recursive filter operation in a first
direction through a sequence of pixels to form a first filtered pixel value for each pixel, and …

Embodiments of the present invention disclose a system and method for reducing noise in a
digital image. The method comprises calculating a spatial weight for each pixel s in a current …
