Abstract: A method is provided for preventing a collision between a motor vehicle and a pedestrian. The method uses a camera and a processor mountable in the motor vehicle. A candidate image is detected. Based on a change of scale of the candidate image, it may be determined that the motor vehicle and the pedestrian are expected to collide, thereby producing a potential collision warning. Further information from the image frames may be used to validate the potential collision warning. The validation may include an analysis of the optical flow of the candidate image, that lane markings prediction of a straight road, a calculation of the lateral motion of the pedestrian, if the pedestrian is crossing a lane mark or curb and/or if the vehicle is changing lanes.

Abstract: A raw byte sequence payload describing a picture in slices, WPP substreams or tiles and coded using context-adaptive binary arithmetic coding is subdivided into tranches with continuing the context-adaptive binary arithmetic coding probability adaptation across tranche boundaries. Thereby, tranche boundaries additionally introduced within slices, WPP substreams or tiles do not lead to a reduction in the entropy coding efficiency of these entities. However, the tranches are smaller than the original slices, WPP substreams or tiles and accordingly they may be transmitted earlier, i.e. with lower delay, than the un-chopped original entities. According to another aspect combinable with the first aspect, substream marker NAL units are used within a sequence of NAL units of a video bitstream to enable a transport demultiplexer to assign data of slices within NAL units to the corresponding substreams or tiles so as to be able to, in parallel, serve a multi-threaded decoder with the corresponding substreams or tiles.

Abstract: The quantization parameter QP is well-known in digital video compression as an indication of picture quality. Digital symbols representing a moving image are quantized with a quantizing step that is a function QSN of the quantization parameter QP, which function QSN has been normalized to the most significant bit of the bit depth of the digital symbols. As a result, the effect of a given QP is essentially independent of bit depth a particular QP value has a standard effect on image quality, regardless of bit depth. The invention is useful, for example, in encoding and decoding at different bit depths, to generate compatible, bitstreams having different bit depths, and to allow different bit depths for different components of a video signal by compressing each with the same fidelity (i.e., the same QP).

Abstract: A method and system for determining if an individual is impaired. In one embodiment, physical and cognitive testing of the individual are conducted in the field or at the scene of an event. The test results are compared to previously stored baseline test results taken for the specific individual while the individual is known to be in an unimpaired state or condition. The current test results are electronically compared to the baseline test results and if the results differ or deviate beyond a predetermined level or amount the individual is considered to be impaired. If no baseline test results exist for the specific individual, the current test results can alternatively be compared to previously determined or known scientifically accepted or minimums for the specific tests given to the individual.

Abstract: Turbine engines are inspected by insertion of a zoom image or foveated image optical head through internal passages within the engine. The zoom image optical generates a first magnified image portion or a second image portion having a wider field of view and lower magnification. The foveated image optical head has a central first image portion having higher magnification that is included within and subtended by a second image portion having a wider field of view. The foveated or zoom image first and second image portions are separately simultaneously displayed on a common display, so that navigation position of the optical head and the magnified inspection image are correlated. In this way an inspector can confirm what area of interest within the turbine has been inspected while evaluating the adjacent magnified inspection image. The dual images correlation can be documented, such as by storing the simultaneously displayed images.

Abstract: Combustion or steam turbine engines internal areas of interest are inspected by insertion of a foveated image optical head through internal passages within the engine. The foveated image optical head has a central first image portion having higher magnification and smaller field of view that is included within and subtended by a second image portion having a wider field of view and lower magnification. The foveated image optical head facilitates maneuvering the borescope optical head through the turbine engine with the wider field of view second image portion to areas of interest, then performing a more detailed inspection by viewing the higher magnification first image portion. The optical head lenses are in fixed positions, sharing a single, common optical path and a common electronic image sensor. This lens and detector arrangement facilitates construction of a compact optical head, allowing passage through small diameter engine inspection ports.
