Abstract: A method for detecting a vehicle via a vehicular vision system includes equipping a vehicle with a camera and providing a control at the equipped vehicle. Frames of image data captured by the camera are processed, via an image processor of the control. Responsive at least in part to (i) vehicle motion information of the equipped vehicle and (ii) processing, via the image processor, of frames of image data captured by the camera, detecting a vehicle present in the field of view of the camera and determining motion of the detected vehicle relative to the moving equipped vehicle, wherein determining motion of the detected vehicle relative to the moving equipped vehicle includes (i) determining corresponding feature points of the detected vehicle in at least two frames of captured image data and (ii) estimating vehicle motion trajectory of the detected vehicle based on the determined corresponding feature points.
Abstract: A method of scanning a surface of an object using a confocal imaging system comprises the steps of obtaining first, second and third confocal images of the surface of the object when the object is illuminated respectively by light rays having first, second and third spectral waveforms, and using a camera to capture responsive signals from the object illuminated by the first, second and third spectral waveforms. The first, second and third spectral waveforms are distinguishable from one another and each spectral waveform has overlapping portions relative to another spectral waveform. Thereafter, heights of a plurality of points on the surface of the object corresponding to the plurality of points on each confocal image are determined based on said captured responsive signals.
Abstract: A system includes an optical waveguide configured to receive multispectral radiation from a scene, a first optical component and a second optical component. The first optical component is configured to cause a first portion of the multispectral radiation with wavelengths in a first range to exit the optical waveguide at a first position, and a second portion of the multispectral radiation with wavelengths in a second range to travel through the optical waveguide from the first position to a second position via total internal reflection. The second optical component is configured to cause the second portion of the multispectral radiation to exit the optical waveguide at the second position.
Abstract: An encoder for encoding a video signal, comprising a video modelling module configured for determining a plurality of video modelling parameters for a plurality of video locations on a spatiotemporal grid of said video signal, said spatiotemporal grid comprising at least two spatial dimensions and a time dimension, each video modelling parameter being adapted for allowing a pre-determined video model to at least approximately reconstruct its video location, a video segmentation module configured for segmenting said video signal into a plurality of spatiotemporal video regions, based on said video modelling parameters and a vectorisation module configured for vectorising spatiotemporal surfaces of said spatiotemporal video regions; and wherein said encoder is configured for encoding said video signal based on at least a subset of said determined plurality of video modelling parameters and based on said vectorised spatiotemporal surfaces, wherein said subset is determined taking into account said spatiotemporal
Abstract: The present invention relates to a method for inducing a merge candidate block and a device using same. An image decoding method involves decoding motion estimation region (MER) related information; determining whether or not a predicted target block and a spatial merge candidate block are included in the same MER; and determining the spatial merge candidate block to be an unavailable merge candidate block when the predicted target block and the spatial merge candidate block are included in the same MER. Accordingly, by parallely performing the method for inducing a merge candidate, parallel processing is enabled and the computation amount and implementation complexity are reduced.

Abstract: A floating calibration target for an image sensor can include a plurality of hexagonally shaped floatation devices that each emit light at one or more predetermined wavelengths. The floating calibration target can also include a seine net circumscribing the plurality of hexagonally shaped floatation devices. The seine net draws the plurality of hexagonally shaped floatation devices toward each other to form a substantially contiguous surface for the floating calibration target.

Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.
