Abstract: A system and method for refocusing an image including determining a point spread function (PSF) according to region of interest (ROI) and pixel depth, and converting the PSF to a gradient domain including differentiating the PSF to reduce nonzero elements in the PSF. The technique spreads intensity of pixels into a circle of confusion per the differentiated PSF. A shape of an optical system or aperture of the imaging device may be considered.

Abstract: Techniques are provided for segmentation of objects in video frames. A methodology implementing the techniques according to an embodiment includes receiving image frames, including an initial reference frame, and receiving a mask to outline a region in the reference frame that contains the object to be segmented. The method also includes calculating Gaussian mixture models associated with both the masked region and a background region external to the masked region. The method further includes segmenting the object from a current frame based on a modelling of the pixels within an active area of the current frame as a Markov Random Field of nodes for cost minimization. The costs are based in part on the Gaussian mixture models. The active area is based on the segmentation of a previous frame and on an estimation of optical flow between the previous frame and the current frame.

Abstract: Techniques related to disparity search range compression are discussed. Such techniques may include determining a combination of disparity search values that do not coexist in any search range of multiple search ranges each associated with pixels of an initial disparity map, compressing the combination of disparity values to a single disparity label, and performing a disparity estimation based on a disparity search label set including the single disparity label.

Abstract: In one example, a system for real-time three-dimensional (3D) calibration includes a processor detecting mark corners at two-dimensional (2D) coordinates in an image coordinate system of an image of a specified pattern. The processor determines 3D coordinates of the mark corners in a world coordinate system based on the pattern. The 3D coordinates correspond to the 2D coordinates. The processor determines baseline depth values corresponding to original depth values for proper points on a mark plane, based on the 2D coordinates and the 3D coordinates. The processor generates a fitting model based on the baseline depth values.

Abstract: Image scene labeling with 3D image data. A plurality of pixels of an image frame may be label based at least on a function of pixel color and a pixel depth over the spatial positions within the image frame. A graph-cut technique may be utilized to optimize a data cost and neighborhood cost in which at least the data cost function includes a component that is a dependent on a depth associated with a given pixel in the frame. In some embodiments, in the MRF formulation pixels are adaptively merged into pixel groups based on the constructed data cost(s) and neighborhood cost(s). These pixel groups are then made nodes in the directed graphs. In some embodiments, a hierarchical expansion is performed, with the hierarchy set up within the label space.
