Abstract: A system for robust disparity estimation in the presence of significant intensity variations for camera arrays is described herein. The system comprises a camera array, a memory and a processor. The memory is configured to store imaging data. The processor is coupled to the memory and the camera array. When executing instructions, the processor is to obtain a plurality of images and generate a sequence of color matched images, wherein the sequence includes each pair of images in the plurality of images. The processor is also to calculate a plurality of disparity points based on the sequence of color matched images.

Abstract: Techniques related to tracking regions of interest across video frames with corresponding depth maps are discussed. Such techniques may include motion tracking feature points of a region of interest, filtering the tracked feature points, determining a center of the region of interest, verifying a depth consistency of the center, and, if the number of tracked feature points falls below a threshold or the center fails depth consistency for a current frame, re-initializing the region of interest in a prior frame.

Abstract: Techniques for improved focusing of camera arrays are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an imaging management module, and the imaging management module may be operable by the processor circuit to determine, for each of a plurality of candidate displacement factors for an image array comprising a plurality of images, a corresponding sharpness, determine an optimal displacement factor comprising a candidate displacement factor corresponding to a maximized sharpness, and transform the image array based on the optimal displacement factor. Other embodiments are described and claimed.
