    Abstract: An image processing method is provided. The method includes the step of comparing each of the input pixels in an input image to a corresponding buffered pixel in a buffered image, and computing the difference value between the input pixel value of the input pixel and the buffered pixel value of the buffered pixel. The method further includes the step of generating a blended image based on the input pixel values and the corresponding difference values. The method further includes the step of determining whether a criterion associated with the difference value is met, for each of the difference values. The method further includes the step of updating, for each of the buffered pixels in the buffered image, the buffered pixel value based on the corresponding input pixel value if the criterion is met, and keeping the buffered pixel value unchanged if the criterion is not met.

    Abstract: Methods and apparatus of compression for non-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. According to one embodiment, the system uses a RIBC (Remapped Intra Block Copy) mode, where the block vector (BV) or BV predictor is remapped using calibration data to reduce the search range. The mapped BV or BVP is also more efficient for coding. A color scaling process can be used with the RIBC mode to compensate the color/brightness discrepancy between images from different cameras. A projection-based Inter prediction method is also disclosed. The projection-based Inter prediction method takes into account different perspectives between two images captured from different cameras. Transform matrix is applied to a block candidate to project the block candidate to a position of a target block. The projected block candidate is used as a predictor for the target block.

    Abstract: A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units.

    Abstract: A transmitter device includes a processing unit and a compression unit. The processing unit obtains a branch of data and partitions the branch of data into a plurality of snippets. Each snippet includes a group of data. The compression unit compresses each snippet into a plurality of packets according to value of each datum included in the corresponding snippet. The compression unit compares the value of each datum with a first threshold value to generate a first packet. The first packet includes first information indicating which data included in the corresponding snippet has the corresponding value not equal to the first threshold value. The compression unit further generates the remaining packets according to the first information.
