摘要： A system and method of the present disclosure provides a block, or region, based error diffusion process for reducing artifacts in images. The system and method allows for the generation and the control of the spatial frequency of a masking signal, e.g., noise, in a way that it can be easily passed through the compression process. The system and method provides for selecting a block size of pixels of the image, adding a masking signal to the image, determining a quantization error for at least one block in the image, and distributing the quantization error to neighboring blocks in the image to mask artifacts in the image. An output image is then encoded with a compression function.

摘要： An apparatus and method of the present disclosure provides an automatic banding region detection function for detecting an image region that has a smooth linear transition of color intensity and is prone to have banding artifacts in image processing. The apparatus and method use a parametric model based approach to detect the banding region. The apparatus and method provide for segmenting at least one first image into at least one homogeneous color region (304), estimating the linear transition of color intensity for the at least one homogeneous color region (308), and if the linear transition of color intensity is substantially smooth, classifying the at least one homogenous color region as a banding region (310).

摘要： Methods and systems for resizing an image utilizing content-aware seam operations include defining low-energy seams defining contextually less-important information and utilizing such information for interpolation based on one-dimensional manifolds. The interpolation can form new seams and/or regenerated pixels that can be combined with the image to provide a content-aware resized image exhibiting smooth and continuous features.
