摘要: Apparatus, systems, and methods disclosed herein operate to produce an image alignment shift vector used to shift left and right image portions of a stereoscopic image with respect to each other in order to reduce or eliminate undesirable horizontal and vertical disparity components. Vertical and horizontal projections of luminance value aggregations from selected left and right image pixel blocks are correlated to derive vertical and horizontal components of a disparity vector corresponding to each left/right pixel block pair. Disparity vectors corresponding to multiple image blocks are algebraically combined to yield the image alignment shift vector. The left and/or right images are then shifted in proportion to the magnitude of the image alignment shift vector at an angle corresponding to that of the image alignment shift vector.

摘要: Deblurring of digital camera images by estimating the blur function from an image extracted from a video sequence taken about the time of an image capture. The extracted image is selected to be the sharpest of the images of the video sequence, and comparison of this sharpest image with the (down-sampled) captured image provides blur function iterative estimation.

摘要: Stabilization for devices such as hand-held camcoders segments a low-resolution frame into a region of reliable estimation, refines the motion vectors of that region hierarchically while at the same time updating the segmentation, finds a global motion vector for the region at high resolution, and uses the global motion vector to compensate for jitter.
