Abstract: An object detection system and a method of detecting an object in an image are disclosed. In an embodiment, a method for detecting the object includes computing one or more feature planes of one or more types for each image pixel of the image. A plurality of cells is defined in the image, where each cell includes first through nth number of pixels, and starting locations of each cell in the image in horizontal and vertical directions are integral multiples of predefined horizontal and vertical step sizes, respectively. One or more feature plane summations of one or more types are computed for each cell. A feature vector is determined for an image portion of the image based on a set of feature plane summations, and the feature vector is compared with a corresponding object classifier to detect a presence of the corresponding object in the image portion of the image.

Abstract: A video system includes an encoder for generating a compressed bit stream in response to a received video signal. A transitional location is located in the bit stream that includes skip macro-block encoding, where the transitional location provides an indication where a linear relationship starts to exist between a length of the encoded bit stream and a length of a number of skipped macro-blocks. The skipped macro-blocks in the bit stream before the transitional location are encoded using a predetermined nonlinear relationship between the length of the encoded bit stream and the length of the number of skipped macro-blocks, whereas skipped macro-blocks in the bit stream are encoded using a linear relationship between the length of the encoded bit stream and the length of the number of skipped macro-blocks.

Abstract: The method, system, and apparatus of a shared error resiliency path through coefficient reordering is disclosed. In on embodiment, determining that an input data is data-partitioned, performing a discrete cosine transform and a quantization of the input data to form a quantized data, separating a first coefficient representing a DC coefficient of the quantized data for each block of the input data, rearranging other coefficients representing AC coefficients of the quantized data for each block of the input data in a fashion produces a zig-zag scan output similar to that of a non-data-partitioned data, bypassing a DC encoding module, determining whether any of the rearranged AC coefficients of the quantized data need to be encoded, performing a zig-zag scan on the rearranged AC coefficients of the quantized data when they need to be encoded, and encoding the rearranged AC coefficients of the quantized data based on the zig-zag scan.
