A method and an image processing device for generating an image filter are proposed. The method includes the following steps. A first image is received and inputted into a pre-trained convolutional neural network (CNN) model, and the image filter corresponding to the first image is obtained based on an output result of the pre-trained CNN model.

Method and image processing device for generating image filter

A motion estimation method and a motion estimator are provided. The motion estimation method includes the following steps of for each respective block of the current frame, selecting a candidate set associated with the current frame and a previous frame, and determining a motion vector according to the candidate set for the each respective block of the current frame. The candidate set includes at least one spatial candidate block in the current frame and temporal candidate blocks in the previous frame. The step of selecting the candidate set includes: selecting the spatial candidate block directly adjacent to the each respective block from the current frame and selecting the plurality of temporal candidate blocks directly adjacent to a reference block from the previous frame.

Motion estimation method and motion estimator for estimating motion vector of block of current frame

A motion estimation method for a frame rate converter includes generating a plurality of unidirectional motion vectors (MVs) based on a first original frame and a second original frame; classifying each of the plurality of unidirectional MVs as a reliable MV or a mismatch MV; mapping the reliable MV onto one of a plurality of blocks of an interpolation frame; classifying each of the plurality of blocks as a high confidence block or a low confidence block based on whether there is at least one reliable MV mapped onto the block; and determining an assigned MV for each of the high confidence block by selecting one of the at least one reliable MV mapped onto the high confidence block.
