Abstract: Innovations in encoding of video pictures in a high-resolution chroma sampling format (such as YUV 4:4:4) using a video encoder operating on coded pictures in a low-resolution chroma sampling format (such as YUV 4:2:0) are presented. For example, according to a set of decision rules, high chroma resolution details are selectively encoded on a region-by-region basis such that increases in bit rate (due to encoding of sample values for the high chroma resolution details) happen when and where corresponding increases in chroma resolution are likely to improve quality in noticeable ways. In this way, available encoders operating on coded pictures in the low-resolution chroma sampling format can be effectively used to provide high chroma resolution details.

Abstract: A method, including receiving signals, from a rectangular array of sensor elements arranged in rows and columns, corresponding to an image captured by the array. The method also includes analyzing the signals along a row or a column to identify one or more local turning points, and processing the signals at the identified local turning points to recognize fixed pattern noise in the captured image. The method further includes correcting values of the signals from the sensor elements at the identified local turning points so as to reduce the fixed pattern noise in the image.

Abstract: Various examples described herein are directed to systems and methods for stabilizing a panoramic video. The panoramic video may comprise a first frame captured by a panoramic camera. The panoramic camera may be positioned in a three-dimensional camera space described by an x-axis, a y-axis, and a z-axis that are mutually orthogonal. The first frame may comprise a plurality of pixel values arranged in a pixel plane and may be continuous in a first dimension. An image processor may receive from a motion sensor data describing a rotation of the panoramic camera at a time when the panoramic camera captured the first frame. The image processor may determine a planar component of an unintended rotation of the panoramic camera about the z-axis and convert the planar component of the unintended rotation to a first frame shift in the first dimension.

Abstract: A method for verifying a lighting setup used for inspecting a micro defect. The method includes simulating a scene including a micro defect, light source and imaging device. A position of the light source and imaging device is then optimized to form an optimized simulated setup for viewing micro defect. A shadow calibration reference (SCR) having a simulated shadow field is then rendered in a location. Next, a physical imaging device and light source are positioned based on information from the optimized simulated setup to form an optimized physical setup. A physical SCR based on information from the SCR rendering is fabricated. Next, an image is captured of a physical SCR in a corresponding location associated with each SCR rendering. The optimized physical setup is verified if at least one shadow parameter from the SCR rendering is substantially similar to a corresponding shadow parameter in a corresponding image.

Abstract: An object detection circuit detects an object moving in a periphery of a vehicle by use of a shot image. A state judgment part changes a parameter relevant to a detection function so as to change whether the detection function of the object detection circuit is to be enabled or disabled while the object detection circuit is kept activated. Thus, even when the detection function of the object detection circuit is disabled, the object detection circuit is kept activated. Therefore, since there is no need to restart the object detection circuit in order to enable the detection function of the object detection circuit, a detection result by the object detection circuit is promptly obtained.

A display selection unit is, provided which, on the basis of the recognition result and a degree of priority of the recognition result, prioritizes the video from each of the cameras according to the degree of priority.

Abstract: Disclosed are an intra prediction method of a chrominance block using a luminance sample and an apparatus using the same. An image decoding method comprises the steps of: calculating an intra prediction mode of a chrominance block on the basis of an LM mapping table when the chrominance block uses an LM; and generating a prediction block for the chrominance block on the basis of the calculated intra prediction mode of the chrominance block. When intra prediction mode information of chrominance blocks are decoded, mutually different tables are used depending on whether or not an LM is used, so that encoding and decoding can be performed without an unnecessary waste of bits.

Abstract: Systems and methods can operate to deliver video information over IP networks on a best-effort basis. Best-effort implies that information is delivered without any guaranteed quality of service. During the encoding of video transport streams into video frames, a decoding time stamp (DTS) can be generated that can be used by a video decoder to determine when to begin decoding the video frame data. Information from one or more video frames can be encapsulated in an IP packet. Using the DTS, video encoding rate and video frame size, a time constraint value can be calculated and can provide an indication of the relative transmission priority for the best-effort IP delivery of IP packets containing encapsulated video information.

Abstract: Compensation offsets are provided for a set of reconstructed samples of an image. Each sample has a sample value. A method of providing the compensation offsets comprises selecting, based on a rate distortion criterion, a classification from among a plurality of predetermined classifications. Each predetermined classification has a classification range smaller than a full range of the sample values and is made up of a plurality of classes, each defining a range of sample values within the classification range, into which class a sample is put if its sample value is within the range of the class concerned. A compensation offset is associated with each class of the selected classification for application to the sample value of each sample of the class.

Abstract: This disclosure pertains to devices, methods, and computer readable media for performing positional sensor-assisted panoramic photography techniques in handheld personal electronic devices. Generalized steps that may be used to carry out the panoramic photography techniques described herein include, but are not necessarily limited to: 1.) acquiring image data from the electronic device's image sensor; 2.) performing “motion filtering” on the acquired image data, e.g., using information returned from positional sensors of the electronic device to inform the processing of the image data; 3.) performing image registration between adjacent captured images; 4.) performing geometric corrections on captured image data, e.g., due to perspective changes and/or camera rotation about a non-center of perspective (COP) camera point; and 5.) “stitching” the captured images together to create the panoramic scene, e.g., blending the image data in the overlap area between adjacent captured images.

Abstract: Innovations are provided for encoding and/or decoding video and/or image content using transform coefficient level gradual updating. Transform coefficient level gradual updating can be applied by encoding (or decoding) different subsets of the transform coefficients for the blocks, macroblocks, or other coding unit for each of a sequence of pictures. For example, a first subset of the transform coefficients of the blocks of a first picture can be encoded with the first picture, a second subset of the transform coefficients of the blocks of a second picture can be encoded with the second picture, and so on. A decoder can reconstruct pictures with increasing quality by receiving additional subsets of the transform coefficients.

Abstract: Innovations in encoding and decoding of video pictures in a high-resolution chroma sampling format (such as YUV 4:4:4) using a video encoder and decoder operating on coded pictures in a low-resolution chroma sampling format (such as YUV 4:2:0) are presented. For example, high chroma resolution details are selectively encoded on a region-by-region basis. Or, as another example, coded pictures that contain sample values for low chroma resolution versions of input pictures and coded pictures that contain sample values for high chroma resolution details of the input pictures are encoded as separate sub-sequences of a single sequence of coded pictures, which can facilitate effective motion compensation. In this way, available encoders and decoders operating on coded pictures in the low-resolution chroma sampling format can be effectively used to provide high chroma resolution details.

Abstract: The display device includes a display panel on which sub-pixel pairs are arranged in a lateral direction, and a parallax barrier shutter panel on which sub-openings that can be changed between a light transmittance state and a light-shielding state are arranged in a lateral direction. Arbitrary allocated number of adjacent sub-openings among the plural sub-openings belonging to a reference parallax barrier pitch are put into a light transmittance state, and the remaining sub-openings are put into a light-shielding state, so that a general opening is formed on the parallax barrier shutter panel. A sub-opening pitch of the sub-opening on the boundary part between the adjacent common driving areas is different from the sub-opening pitch of the other sub-openings.
