Abstract: Encoding a digital image divided into a plurality of blocks of pixels processed in a defined order, including the following steps, implemented for a current block, with preset sizes: predicting values of the current block from at least one block previously processed; calculating a residual block by subtracting the predicted values from the original values of the current block; obtaining a residual block by applying a transform to pixels of the residual block, said transformed residual block comprising coefficients; encoding the transformed residual block; calculating at least one characteristic representative of at least one transformed residual coefficient of the current block; determining initial identification data representative of a sub-list of at least one transform associated with said at least one calculated characteristic; and verifying that the transform applied to the current block is part of the sub-list identified by the initial data.

Abstract: A device for MR/VR systems that includes a two-dimensional array of cameras that capture images of respective portions of a scene. The cameras are positioned along a spherical surface so that the cameras have adjacent fields of view. The entrance pupils of the cameras are positioned at or near the user's eye while the cameras also form optimized images at the sensor. Methods for reducing the number of cameras in an array, as well as methods for reducing the number of pixels read from the array and processed by the pipeline, are also described.

Abstract: A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands for a slice of a frame may be buffered so that complexity statistics may be calculated across the frequency bands prior to encoding. The statistics may then be used by a rate control component in determining quantization parameters for the frequency bands for modulating the rate in the encoder for the current slice. The quantization parameters for the frequency bands may be calculated jointly to optimize the quality of the displayed frames after decoder reconstruction and wavelet synthesis on a receiving device. Information about one or more previously processed frames may be used in combination with the statistics for a current slice in determining the quantization parameters for the current slice.

Abstract: A system for assembling a group composite image from individual subject images is described. Often subjects of a group vary in height. Additionally, as each subject is photographed individually, different zoom factors can be applied by a camera that affects a pixel density of the image captured. The system includes a fiducial marking device that emits collimated light to form one or more fiducial markers on a subject while an image is captured by the camera. Based on a location of the fiducial markers in the image, a pixel density of the image and a reference height of the subject can be determined. The individual subject image can be scaled based on the pixel density and reference height to account for the varying subject heights and zoom factors to generate a group composite image that accurately represents the subjects of the group relative to one another.

Abstract: Devices, methods, and systems for monitoring captured images and/or video from one or more cameras are described herein. The systems may include one or more cameras, a video recorder, a mobile display device, and a location detection system. The location detection system may detect a proximity of the mobile display device relative to one or more cameras and determine when the proximity to a camera meets a predetermine proximity criteria. The mobile display device may display at least part of a recorded video stream that is captured by the camera when it is determined the proximity of the mobile display device to the camera meets the predetermined proximity criteria. In some cases, the displayed video may be displayed in a virtual reality or three dimensional format. Further, as the proximity of the mobile display device to the camera changes, a zoom level and/or direction of view of the displayed video may change.

Abstract: A rendering processor assigns varying logical pixel dimensions to regions of an image frame and rendering pixels of the image frame based on the logical pixel dimensions. The rendering processor renders in highest resolution (i.e., with smaller logical pixel dimensions) those areas of the image that are more important (on which the viewer is expected to focus (the “foveal region”), or regions with little-to-no motion), and renders in lower resolution (i.e., with larger logical pixel dimensions) those areas of the image outside the region of interest, or regions that are speedily moving, so that loss of detail in those regions will be less noticeable to the viewer. For regions with less detail or greater magnitude of motion, larger logical pixel dimensions reduce the computational workload without affecting the quality of the displayed graphics as perceived by a user.
