Abstract: A vehicle periphery monitoring apparatus detects the presence of a moving object along a vehicle periphery. The apparatus sets multiple detection lines along a horizontal axis of an image captured by a camera, and detects a brightness change of a pixel along the detection lines. With reference to the brightness change detected along the detection line and a parameter for determining whether such brightness change is caused by the moving object, the apparatus determines the presence of the moving object. In addition, the apparatus changes a determination condition for determining the moving object such that as the number of detection lines along which the brightness change is detected decreases, the harder it is to satisfy the determination condition for determining that the moving object is present.

Abstract: The server device draws a processing result from software in an image memory, detects an update area containing an update between frames in the image, performs still image compression, and calculates the compression ratio of still image compressed data in the update area. The server device identifies a high-frequency change area, performs moving image compression, and calculates the compression ratio of moving image compressed data. The server device transmits the still image compressed data and the moving image compressed data. The server device stops the moving image compression based on the result of comparing the compression ratio of the moving image compressed data and a compression ratio of still image compressed data in a previous update area is the update area in a previous frame detected before the start of the moving image compression and has been detected at a position associated with the high-frequency change area.

Abstract: An improved MPEG-4 to H.264 transcoding algorithm is provided, exploiting residual, coding mode and motion vector information from the MPEG-4 stream. The use of the relative sum of absolute residuals (RSAR) to classify macroblocks (MB) leads to small sets of coding modes (CM) to test, and significantly reduces the computational complexity. In addition, RSAR is used to conditionally refine motion vectors (MV); only those MVs most likely to lead to quality improvements are refined. The average RSAR statistics are obtained from the transcoding of the previous Inter frame to provide adaptive thresholds for coding mode selection as well as conditional MV refinement. A corresponding video transcoder system is also provided.

Abstract: This disclosure describes techniques for encoding digital video data using interpolation filters and offsets. An encoder may be configured to select interpolation filters for sub-pixel precision motion estimation based on historical interpolation results obtained for previously encoded video units, such as frames or slices. The encoder also may be configured to compute and assign offsets to the sub-pixel positions after interpolation based on differences between a reference unit and the unit to be coded. The computation and assignment of offsets may be performed before motion estimation. Motion estimation may be refined so that the motion search considers sub-pixel positions to which offsets have been previously added and evaluates sub-pixel positions that have a non-zero offset. In some cases, interpolation filter selection, offset computation, and/or refined motion estimation for a given unit may be performed in a single encoding pass.
