Abstract: A CNN operates on the disparity or motion outputs of a block matching hardware module, such as a DMPAC module, to produce refined disparity or motion streams which improve operations in images having ambiguous regions. As the block matching hardware module provides most of the processing, the CNN can be small and thus able to operate in real time, in contrast to CNNs which are performing all of the processing. In one example, the CNN operation is performed only if the block hardware module output confidence level is below a predetermined amount. The CNN can have a number of different configurations and still be sufficiently small to operate in real time on conventional platforms.

Abstract: In some embodiments, a computer-readable medium stores executable code, which, when executed by a processor, causes the processor to: capture an image of a finder pattern using a camera; locate a predetermined point within the finder pattern; use the predetermined point to identify multiple boundary points on a perimeter associated with the finder pattern; identify fitted boundary lines based on the multiple boundary points; and locate feature points using the fitted boundary lines.

Abstract: Examples provide for computer executable instructions executable by a processor to configure the processor to determine an occupancy status of cells of a region of interest by, for a first cell of the region of interest, determining whether the first cell is free by setting a free space flag for the first cell to an asserted value and setting a free space tested flag for the first cell to an asserted value responsive to determining that the first cell and each of the surrounding cells in the programmed radius of the first cell are unoccupied, and setting a free space flag for a second cell to a de-asserted value and setting a free space tested flag for the second cell to an asserted value responsive to determining that the second cell is occupied, the second cell being among the surrounding cells in the programmed radius of the first cell.

Abstract: A method for multi-sensor calibration includes imaging a calibration target with a first sensor using a first modality to obtain a first set of data and a second sensor using a second modality that is different from the first modality to obtain a second set of data. A border of the calibration target is identified based on the first set of data. A first centroid location of the calibration target is identified based on the border of the calibration target. A border of a pattern disposed on the calibration target is identified based on the second set of data. A second centroid location of the calibration target is identified based on the border of the pattern. Calibration data for the first sensor and the second sensor is generated based on the first centroid location and the second centroid location.

Abstract: A system includes a downsampling circuit, a stereo disparity engine, and a merge circuit. The downsampling circuit is configured to generate a first two-dimensional array by down sampling a second two-dimensional array, and generate a third two-dimensional array by down sampling a fourth two-dimensional array. The stereo disparity engine is configured to generate a first disparity map relating elements of the first two-dimensional array to elements of the third two-dimensional array, generate a second disparity map based on the first disparity map, a first sub-array of the second two-dimensional array and a second sub-array of the fourth two-dimensional array, and generate a third disparity map based on the first disparity map, a third sub-array of the second two-dimensional array and a fourth sub-array of the fourth two-dimensional array. The merge circuit is configured to combine the second disparity map and the third disparity map to generate a fourth disparity map.

Abstract: Apparatus and methods for disparity cost computation for a stereoscopic image. In an example, a method includes computing partial path matching costs for multiple disparities of pixels of multiple parallelogram blocks of an image in a forward pass direction. Between computing the partial path matching costs of the pixels of adjacent parallelogram blocks, the method includes computing partial path matching costs for the plurality of disparities of pixels along a boundary edge of a corresponding rectangular tile using paths that are external to the rectangular tile and computing partial path matching costs the disparities for all of the pixels of the corresponding rectangular tile. The method also includes computing total aggregated disparity costs for each disparity of the pixels of the image using the partial path matching costs computed for the pixels in the parallelogram blocks and in the rectangular tiles.
