Abstract: Systems and methods for enabling a video capture/encoding device to capture frames of a video sequence; obtain feedback from a video decoding/rendering device; divide each frame into an array of patches; select one or more patches of each frame for supplemental processing; cause the frames of the video sequence to be encoded by a video encoding module and cause the selected patches to be processed by one or more supplemental processing module(s); and assemble a multi-layer video transport stream wherein, for each frame of the video sequence, a base layer of the transport stream includes data corresponding to an encoded version of the current frame and one or more supplemental layers of the transport stream include meta-data corresponding to the division of the current frame into patches and data corresponding to the output of the supplemental processing of the selected patches of the current frame.

Abstract: A further coding efficiency increase may be achieved if for a current block of a picture, for which the bit stream signals one of supported partitioning patterns, a reversal of the partitioning by block merging is avoided. In particular, if the signaled one of the supported partitioning patterns specifies a subdivision of the block into two or more further blocks, a removal of certain coding parameter candidates for all further blocks, except a first further block of the further blocks in a coding order, is performed. Particularly, those coding parameter candidates are removed from the set of coding parameter candidates for the respective further block, the coding parameters of which are the same as coding parameters associated with any of the further blocks which, when being merged with the respective further block, would result in one of the supported partitioning pattern. This avoids redundancy between partitioning coding and merging coding.

Abstract: An image processing device is provided with an image acquiring unit that acquires the image from an imaging unit mounted on a vehicle, a light determining unit that determines a state of a light mounted on the vehicle, and an adjusting unit that adjusts a relationship between a luminance at an object to be captured by the imaging unit, and a pixel value in the image. The adjusting unit is configured to set, when the light determining unit determines the state of the light is in the low-beam state, the illuminance where the pixel value is at the lower limit, to be lower than that of a case when the light determining unit determines the state of the light is in the high-beam state.

Abstract: A method displays information graphically on an image captured by a vehicular optical system. The method includes capturing the image and identifying an object in the image. The method the assigns a priority level to the object based on a predetermined criterion. The object is altered based on its priority level to create an altered object. An altered object may have a changed color, a colored halo surrounding it, or a colored object inside it. Other possible ways to alter the way the object looks are possible. The altered object is displayed in the image in place of the object on a mobile device to alert a person of its presence and the priority level associated therewith.

Abstract: Gaze tracking data is analyzed to determine one or more regions of interest within an image of a video stream. The video stream data is selectively scaled so that sections within the regions of interest maintain high resolution while areas not within the region of interest are down-scaled to reduce bandwidth cost of transmission. A scheme for reduction of motion sickness by reducing the size of the high resolution area is also claimed.

Abstract: Systems and methods are described for control-point based intra mode for coding a video bitstream. In an exemplary embodiment, at least two control points in a picture are selected. The control points may be, for example, points at or adjacent to two or more corners of a current block. For each of the control points, an associated intra prediction direction is identified. The intra prediction directions may be encoded in the bitstream, e.g. using differential coding. A derived intra prediction direction is interpolated based on a position of a pixel (or of a block) relative to the control points, and the derived intra prediction direction is used to predict one or more samples in the video. Different interpolation techniques, such as triangular interpolation or bilinear interpolation may be used.

Abstract: Methods and systems for smooth switching of video sources. One method includes the steps of: Inferring that first and second network paths share a common link that has insufficient bandwidth to carry both the respective first and second incoming high-definition uncompressed videos (HD-UVs) generated by first and second real-time video encoders (RT-VEs). And synchronizing a smooth switching between the first and second incoming HD-UVs by: indicating the first and second RT-VEs to increase their first and second compression ratios to ratios that enable the common link to carry both the first and second compressed videos; indicating a video switcher to perform the smooth switching between the first and second corresponding outgoing HD-UVs; indicating the first RT-VE to stop sending the first compressed video after the smooth switching; and indicating the second RT-VE to decrease the second compression ratio.

Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.

Abstract: The invention relates to a method for scanning microscopy wherein a specimen is scanned simultaneously with a plurality of illumination spots of an excitation light. The light emitted by one specimen location irradiated with one illumination spot is detected independently of the light emitted by another specimen location illuminated with another illumination spot. A microscopic image of the specimen can be compiled from the emitted light detected for the different specimen locations. The method provides that the intensities of the different illumination spots are set independently of one another, and in that the illumination spots are guided over the specimen one after another in a scan line. The invention additionally relates to a scanning microscope.

Abstract: Methods and systems for compression that maintains parameters related to uncompressed video (PRTUV) while changing video compression ratios on-the-fly. One embodiment of a system includes: A video transmitter that receives incoming high-definition uncompressed video (HD-UV) characterized by certain PRTUV. The video transmitter compresses the incoming HD-UV into a first compressed video of ratio between 1:1 and 5:1, and sends it over a communication link to a receiver that decompresses the video to an outgoing HD-UV. When the video transmitter receives a command to smoothly change on-the-fly the compression to a second compressed video of ratio between 2:1 and 10:1, it makes the change without interrupting the continuous flow of the incoming HD-UV. Wherein the outgoing HD-UV maintains the PRTUV before, during, and after the change from the first compressed video to the second compressed video.
