    Abstract: An electronic circuit includes a block determinator, a candidate selector, and a motion vector generator to perform motion estimation. The block determinator determines a current block and candidate blocks with regard to each of decimated images generated from an original image, wherein the block determinator determines first candidate blocks based on a location of the current block without a full search for all pixels with regard to a first decimated image of the lowest resolution. The candidate selector selects second candidate blocks which are some of the first candidate blocks with regard to a second decimated image of the highest resolution, such that the block determinator determines the second candidate blocks with regard to the original image. The motion vector generator generates a motion vector for the current block based on one reference patch determined from reference patches indicated by candidate motion vectors of the second candidate blocks.

    Abstract: An encoder and a video processing system including the encoder are provided. The encoder may include a quantization operation selection circuit configured to generate first data by performing a first quantization operation based on input data including image data of a frequency domain, to generate a feature value based on the first data, and to generate a control signal for selecting a second quantization operation or a rate-distortion optimized quantization (RDOQ) operation based on a machine learning model trained based on training data that includes the feature value. Additionally, the encoder may include a quantizer configured to perform the second quantization operation or the RDOQ operation based on the control signal and to generate output data (e.g., after performing the second quantization operation or the RDOQ operation).

    Abstract: A transform processor may process original data that includes video information by using at least one of first and second processing methods, and generates at least one of first and second transformed data. Index determination logic may determine an index satisfying a determination condition based on at least one of the first and second transformed data. Energy compaction determination logic may determine energy compaction of at least one of the first and second transformed data based on the determined index. Output selection logic may selectively output one of the first and second transformed data based on the determined energy compaction. An entropy encoder may encode data output from the output selection logic.

    Abstract: An electronic circuit includes a block determinator, a candidate selector, and a motion vector generator to perform motion estimation between images. The block determinator determines a current block corresponding to a current location on an image and candidate blocks corresponding to relative locations with respect to the current location for each recursion for blocks constituting the image. The candidate selector selects some of the candidate blocks. The motion vector generator generates a motion vector for the current block based on one reference patch which is determined from reference patches indicated by candidate motion vectors of the selected candidate blocks. At least one of the relative locations corresponding to the candidate blocks selected in a first recursion is different from each of the relative locations corresponding to the candidate blocks selected in a second recursion following the first recursion.

    Abstract: A training operation is performed on the video coding module to generate a personal video parameter based on information on a sensitivity of a user and a preference of a user. An image is received through an imaging device. The image is encoded based on the personal video parameter to generate an encoded image. The encoded image is decoded based on the personal video parameter to generate a first decoded image.
