摘要： In various embodiments, a system and method for manufacturing and using an optical enhancement assembly in combination with an image-capturing device are presented. In example embodiments, the optical enhancement assembly is affixed over an aperture on the image-capturing device using a securing agent. Light is allowed to travel through the optical enhancement assembly and into the aperture of the image-capturing device such that the light can be recorded as a still image or video. The optical enhancement assembly includes at least a unique fractalized diffraction pattern that impacts light traveling into the aperture and causes a unique diffraction effect on the image or video recorded by the image-capturing device.

摘要： A method for extracting an epitome from an image Y is described. The method comprises: searching, for each block, a list of patches in the image Y with similar content; determining, for each patch of said lists, the set of blocks able to be represented by the patch; constructing, from the sets of blocks, epitome charts comprising, for each epitome chart, initializing said epitome chart with one patch and extending said epitome chart with at least one candidate region contained in a patch overlapping said epitome chart; said method being characterized in that said candidate region is selected by taking into account the blocks represented by said patch overlapping said epitome chart and by any other patch contained in said epitome chart enlarged by said selected candidate region.

摘要： Blocking artifacts are reduced by projecting each patch obtained from an input image onto a set of bases vectors to determine multiple representations for each patch. The set of bases vectors are learned from a training image, and the bases vectors include a full basis vector, and one or two subspace bases vectors. An optimal basis vector is determined in the set of bases vectors for each patch according to the projection. A threshold is applied to coefficients of the optimal basis vector to determine a filtered representation for each patch, and a reconstructed patch is generated using the filtered representation. Then, the aggregating the reconstructed patches are aggregated to produce an output image.

摘要： A method of calculating the discrete cosine transform (DCT) of blocks of pixels of a picture includes the steps of defining first subdivision blocks called range blocks, having a fractional and scaleable size N/2i*N/2i, where i is an integer number, with respect to a maximum pre-defined size of N*N pixels of blocks of division of the picture, referred to as domain blocks, shiftable by intervals of N/2i pixels. The method also includes the step of calculating the DCT on 2i range blocks of a subdivision of a domain block of N*N pixels of the picture, in parallel.

摘要： An image processing apparatus includes a sort unit for sorting original image data into edge image data and planar image data, a first coding unit for coding the sorted planar image data according to the fractal block coding method, and a second coding unit for coding the sorted edge image data according to a coding method differing from the fractal block coding method. Thus, an image processing apparatus is provided that can have picture quality of a reproduced image improved even for a block that has maximum density difference such as an edge portion. The image processing apparatus can include a first coding unit for coding original image data according to the fractal block coding method, an extractor for extracting error between blocks, a comparator for comparing the amount of extracted error with a predetermined value, and a second coding unit for coding error information according to a coding method different from the fractal block coding method when the error amount is greater than the predetermined value as a result of comparison.
