Detecting rapid changes in illuminance using angular differences between vectors in a YUV colour space

Номер: GB0002386277A
Принадлежит:

During post-processing of video data in a YUV color space it may be necessary, for instance for immersive video conferences, to separate a video object in the image foreground from the known image background. Hitherto, rapid, locally limited deviations in illumination in the actual image to be examined, in particular shadows and brightenings, could not be compensated for. The inventive recognition and compensation method of the present invention, however, can compensate for shadows and brightenings in real time, even for great quantities of image data, by directly utilizing different properties of the technically based YUV color space. Chrominance, color saturation and color intensity of an actual pixel (P1) are approximated directly from associated YUV values ( V , a, b) which leads to the avoidance of time-consuming calculations. The recognition of rapid deviations in illumination carried out in the YUV color space is based upon the approximation of a chrominance difference by an angle ...

Принадлежит:

Input images are partitioned into non-overlapping segments perpendicular to a disparity dimension of the input images. Each segment includes a contiguous region of pixels spanning from a first edge to a second edge of the image, with the two edges parallel to the disparity dimension. In some aspects, contiguous input image segments are assigned in a “round robin” manner to a set of sub-images. Each pair of input images generates a corresponding pair of sub-image sets. Semi-global matching processes are then performed on pairs of corresponding sub-images generated from each input image. The SGM processes may be run in parallel, reducing an elapsed time to generate respective disparity sub-maps. The disparity sub-maps are then combined to provide a single disparity map of equivalent size to the original two input images.

Tracking semantic objects in vector image sequences

Номер: US0007162055B2

A semantic object tracking method tracks general semantic objects with multiple non-rigid motion, disconnected components and multiple colors throughout a vector image sequence. The method accurately tracks these general semantic objects by spatially segmenting image regions from a current frame and then classifying these regions as to which semantic object they originated from in the previous frame. To classify each region, the method performs a region based motion estimation between each spatially segmented region and the previous frame to compute the position of a predicted region in the previous frame. The method then classifies each region in the current frame as being part of a semantic object based on which semantic object in the previous frame contains the most overlapping points of the predicted region. Using this method, each region in the current image is tracked to one semantic object from the previous frame, with no gaps or overlaps. The method propagates few or no errors because ...

A method for determining, for example within a digital camera, whether a pixel belongs to a foreground or background segment within an image by evaluating derivative or deviation metrics (e.g. the ratio of derivate metric over deviation metric) in an area (block) around each pixel in the image, or ratios of derivative metrics across plural images, each captured at a different focus position. For each pixel, a block of pixels are examined to determine 406 an aggregate relative derivative (ARD), a block-based derivative; this derivative can be seen as a measure of defocus blur around an image location. The ARD is used, e.g. compared to a threshold value, to determine whether the pixel is to be assigned in the foreground segment or background segment. Multiple images may also be used to obtain ratios of a numerator of the ARD, to determine an extent of the foreground. The derivative metric may be determined from maximum and minimum derivatives for respective horizontal and vertical luminance ...

Robust techniques for self-calibration of a moving camera observing a planar scene. Plane-based self-calibration techniques may take as input the homographies between images estimated from point correspondences and provide an estimate of the focal lengths of all the cameras. A plane-based self-calibration technique may be based on the enumeration of the inherently bounded space of the focal lengths. Each sample of the search space defines a plane in the 3D space and in turn produces a tentative Euclidean reconstruction of all the cameras that is then scored. The sample with the best score is chosen and the final focal lengths and camera motions are computed. Variations on this technique handle both constant focal length cases and varying focal length cases.

A system and method implemented as a software tool for foreground segmentation of video sequences in real-time, which uses two Competing 1-class Support Vector Machines (C-1SVMs) operating to separately identify background and foreground. A globalized, weighted optimizer may resolve unknown or boundary conditions following convergence of the C-1SVMs. The objective of foreground segmentation is to extract the desired foreground object from live input videos, with fuzzy boundaries captured by freely moving cameras. The present disclosure proposes the method of training and maintaining two competing classifiers, based on Competing 1-class Support Vector Machines (C-1SVMs), at each pixel location, which model local color distributions for foreground and background, respectively. By introducing novel acceleration techniques and exploiting the parallel structure of the algorithm (including reweighing and max-pooling of data), real-time processing speed is achieved for VGA-sized videos.
