Abstract: The invention provides a motion prediction method. First, a plurality of motion vector predictors is obtained to be included in a candidate set for motion prediction of a current unit of a current frame. Whether the current frame is a non-reference frame which is not referred to by other frames for motion prediction is then determined. When the current frame is not the non-reference frame, any motion vector predictor corresponding to a previously coded frame is removed from the candidate set, and a motion vector of the current unit is predicted according to the motion vector predictors of the candidate set.

Abstract: An exemplary method for decoder-side motion vector derivation (DMVD) includes: checking a block size of a current block to be encoded and accordingly generating a checking result; and utilizing a DMVD module to refer to the checking result to control conveyance of first DMVD control information which is utilized for indicating whether a DMVD coding operation is employed to encode the current block. When the checking result indicates a predetermined criterion is satisfied, the first DMVD control information is sent in a bitstream; otherwise, the first DMVD control information is not sent.

Abstract: The invention provides a motion prediction method. First, a plurality of candidate units corresponding to a current unit of a current frame is determined A plurality of motion vectors of the candidate units is then obtained. A plurality of temporal scaling factors of the candidate units is then calculated according to a plurality of temporal distances between a plurality of reference frames of the motion vectors and the current frame. The motion vectors of the candidate units are then scaled according to the temporal scaling factors to obtain a plurality of scaled motion vectors. Finally, a motion vector predictor for motion prediction of the current unit is then selected from the candidate units according to the scaled motion vectors.

Abstract: A region-based method for iterative regularization image enhancement, includes: for each region of a plurality of regions of an image, performing at least one gradient calculation of an objective function of a latest representative function of the region and updating the latest representative function according to the gradient calculation; and for the region of the plurality of regions of the image, when at least one predetermined convergence criterion is not satisfied, iteratively updating the latest representative function according to at least one gradient calculation of the same objective function of the latest representative function. In particular, the region-based method further includes: for the region of the plurality of regions of the image, when the predetermined convergence criterion is satisfied, performing postprocessing on the latest representative function of the region to generate an iteratively regularized partial image corresponding to the region.

Abstract: A method and system is proposed for generating index pictures for video streams, where the index pictures can be used in a video database for visual browsing by users to quickly find and retrieve video clips or files from the video database. The proposed method and system operates in such a manner as to first create a set of content items of particular interest or concern (particularly moving objects), and then combine each content item together with an associated activity record dataset in a predefined manner into a single image to serve as an index picture. In practice, each moving object and its associated activity record dataset can be displayed by means of 2D (two-dimensional) or 3D (three-dimensional) graphic icons or imagery.
