Abstract: A system includes a memory and a display. The system also includes a processor coupled to the memory and to the display. The processor is configured to obtain an image and determine a parent cluster of pixels of an image having a centroid. The processor is also configured to split the parent cluster into at least a first child cluster and a second child cluster and assign a pixel of the image to the first child cluster. Additionally, the pixel is configured to update a centroid of the first child cluster responsive to the pixel and replace the pixel in the image with the centroid of the first child cluster to produce a compressed image. Also, the processor is configured to store the compressed image in the memory, where the display is configured to display the compressed image.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to warp images for video processing. An example device includes horizontal warper circuitry configured to access an input image, decimate a first set of pixels in the input image by row, and interpolate a second set of pixels in the input image by row to produce a horizontally warped image. The example device further includes vertical warper circuitry configured to access the horizontally warped image, decimate a first set of pixels in the horizontally warped image by column, and interpolate a second set of pixels in the horizontally warped image by column to produce an output image.

Abstract: System and method for generating multiprimary signals with optimization for bit depth for use in display devices. A preferred embodiment comprises converting an input color signal into an output color signal, wherein the number of colors in the output color signal is less than a number of colors used in a display system, when a weighting of the input color signal is less than a specified threshold, and converting the input color signal into an output color signal, wherein the number of colors in the output color signal is equal to the number of colors used in the display system, when the weighting of the input color signal is greater than the specified threshold. The use of fewer colors eliminates low bit depth colors, allowing increased dither quality in dimmer images.

Abstract: Methods and apparatus for optical filtering. In one example, a device includes a spatial light modulator having a two-dimensional array of square, rectangular, or diamond pixels, and a controller coupled to the spatial light modulator. The controller can be configured to write image data representing an image to the spatial light modulator to control the spatial light modulator to display the image for a frame period, and during the frame period, spatially reposition the image on the array of pixels over a plurality of positions, each individual position of the plurality of positions being maintained for a respective time period, wherein the respective time period is selected according to one or more non-negative coefficients of an anti-aliasing filter transfer function.
