Abstract: A dual-camera apparatus derives dimensional measurements of an object. The apparatus comprises a pair of digital cameras each comprising a lens and capable of producing an image of the object. A ratio of known distance units to pixels is established for the apparatus and applied to images generated by each of the digital cameras. The lenses are spaced apart at a first known distance. In operation, the first known distance and the established ratio provide a trigonometric basis for ascertaining distances between at least two features on the object. A calibration template can be used to establish the ratio of known distance units to pixels. The object can be a human subject, and the at least two features can be associated with the human subject's eyes, the human subject's feet, and/or other human body parts. The disclosure also relates to a method in aiding in lens selection.

Abstract: Deblocking filters used in video coding systems (e.g., single layer video coding systems or multi-layer video coding systems) may be enhanced. Inter layer prediction for scalable video coding (SVC) may be implemented using enhanced deblocking filters. Enhanced deblocking filters may be configured to be adapted, for example by adjusting a deblocking filter boundary strength calculation process. A deblocking filter boundary strength parameter may be assigned in accordance with, for example, a video block partition size of an input video block or a neighboring video block, whether an input video block or a neighboring video block was predicted using an inter layer reference, and/or whether at least one of an input video block or a neighboring video block have one or more corresponding base layer blocks that were coded using intra mode.

Abstract: A method and apparatus for significance map context selection are disclosed. According to the present invention, the TUs are divided into sub-blocks and at least two context sets are used. Non-DC transform coefficients in each sub-block are coded based on the same context, context set, or context formation. The context, context set, or context formation for each sub- block can be determined based on sub-block index in scan order, horizontal sub-block index, vertical sub-block index, video component type, TU width, TU height, or any combination of the above. In one embodiment, the sum of the horizontal and the vertical sub-block indexes is used to classify each sub-block into a class and the context, context set, or context formation is then determined according to the class.

Abstract: A method and system determines object orientation using a light source to create a shadow line extending from the light source. A camera captures an image including the shadow line on an object surface. An orientation module determines the surface orientation from the shadow line. In some examples a transparency imperfection in a window through which a camera receives light can be detected and a message sent to a user as to the presence of a light-blocking or light-distorting substance or particle. A system can control illumination while imaging an object in space using a light source mounted to a support structure so a camera captures an image of the illuminated object. Direct illumination of the camera by light from the light source can be prevented such as by blocking the light or using a light-transmissive window adjacent the camera to reject light transmitted directly from the light source.

Abstract: An imaging sensor produces spatiotemporal measurement sets of distinct sensing zones of the imaging sensor. A multifocal lens directs electromagnetic radiation from distinct three-dimensional spatial zones to distinct sensing zones. A focus analyzer processes the spatiotemporal measurement sets to determine a sequence of in-focus status of the distinct sensing zones independent of other distinct sensing zones. A displacement processor generates object displacement vector(s) based on a sequence of in-focus status indicative of an object moving between distinct three-dimensional spatial zones.
