摘要： In at least some examples, a system comprises a processor and a memory coupled to the processor. The memory stores an image defect visibility predictor that, when executed by the processor, compares an original image with a defect image and outputs a predicted defect visibility image (PDVI) that accounts for defect masking by the original image.

摘要： In one example, a method for glare and shadow mitigation by fusing multiple frames includes illuminating the target with light from a first illumination direction and capturing a first frame of the target with a camera while the target is illuminated in the first illumination direction. The method also includes illuminating the target with light from a second illumination direction and capturing a second frame of the target with the camera while the target is illuminated in the second illumination direction. The first frame and second frame are fused together to form a composite image that simultaneously mitigates glare and shadow areas.

摘要： A method for designing a screen set for color halftoning includes selecting a screen set that includes at least two screens. The screens are applied to a uniform color image so as to form a set of corresponding colorant halftones. The colorant halftones are superposed to form a color halftone. A spatial frequency spectrum of the color halftone is calculated. Maxima of the spatial frequency spectrum that occur at two effective frequencies are identified, the two effective frequencies being located in two adjacent quadrants of a complex spatial frequency space. A magnitude of each effective frequency is compared with a predetermined frequency magnitude. The screen set is accepted for future application for color halftoning only if both effective frequency magnitudes are greater than the predetermined frequency magnitude. Relating computer program product and data processing system are also disclosed.

摘要： A method for creating an image to be printed is provided. A first halftone pattern and a second halftone pattern for respective first and second periodic clustered dot halftone regions of the image are selected. The regions have respective frequencies and one of the frequencies is higher than the other frequency. A transition region is determined. The transition region includes a boundary between the two regions and includes additional portions of the two regions beyond the boundary. The two halftone patterns are blended with each other in the transition region based on a blending ratio of the two halftones where the blending ratio changes as a function of distance between the edges of the transition region.

摘要： The present disclosure includes a system and method for symbol compression using conditional entropy estimation. One method for symbol compression using conditional entropy estimation includes approximating a quantity of symbol encoding bits for a number of symbols using a conditional entropy estimation. Dictionary entries are generated from the number of symbols so as to minimize a total bit-stream quantity. The total bit-stream quantity includes at least the approximated quantity of symbol encoding bits and a quantity of dictionary entries encoding bits. The symbols are encoded using the dictionary entries as a reference.

摘要： Disclosed are techniques for video stream compression. A motion predicted frame and a current frame of video data are converted from a source color space to a perceptual color space. A delta (Δ) frame is calculated between the current frame and the motion predicted frame. Input color difference values between the current frame and the motion predicted frame are determined and mapped to a normalized output to create a tone mapped color difference image. The tone mapped color difference image and Δ frame are multiplied to obtain a weighted Δ frame. Δ loss is calculated as the difference between the weighted Δ frame and the Δ frame. A variance map of the motion predicted frame is multiplied by the Δ loss to obtain a Δ preservation map. The weighted Δ frame and Δ preservation map are summed to obtain a modified Δ frame which may be transformed, quantized and encoded.
