Abstract
Techniques for removal of interference patterns from digital images are described, in which a spatially-adaptive filter is applied to a pixel based on a context of the pixel. In an example, an edge of an object in a digital image is located in a digital image creation system. Then, context data is generated for a pixel in the digital image. The context data includes a distance from the edge of the object to the pixel. The digital image creation system can also generate color data and luminance data for the pixel, representing a similarity of color and luminance between the pixel and surrounding pixels within the digital image. Then, the digital image creation system constructs a spatially-adaptive filter for the pixel based on the context data for the pixel. The digital image creation system removes an effect of the interference pattern at the pixel in the digital image by applying the spatially-adaptive filter to the pixel.
