Abstract: There are provided computerized systems and methods of optimized video encoding. The method includes encoding a current video frame by performing an optimized quantization of transform coefficients using a modified rate-distortion cost function. The modified rate-distortion cost function can be obtained by configuring a reconstruction error in a rate-distortion cost function in accordance with a relation associated with the encoding block and the processed encoding block. In such ways, a reconstructed video frame corresponding to the current video frame has optimized perceived visual quality as compared to perceived visual quality of a reconstructed video frame of a corresponding frame bitstream which is generated without using the optimized quantization.

Abstract: There are provided computerized systems and methods of pre-processing video information for optimized video encoding. In various aspects, the pre-processing can be performed in different ways. By way of example, this can be performed by aligning a plurality of consecutive frames in the sequence of video frames. By way of another example, this can be performed by conducting adaptive pre-filtering of the video information. By way of yet another example, this can be performed by filtering the video information in order to remove grain content thereof.

Abstract: There are provided computerized systems and methods for detection of objects in a one or more images or video frames, which require reduced power or computational cost compared to existing methods. The proposed approach uses a set of per frame detection anchors which are split into a primary sub-set and one or more secondary sub-sets. For each key frame a full detection process for each of the detection anchors in primary subset is performed, determining for each detection anchor whether it corresponds to a detected object, and updating a detected object data structure accordingly. For each non ‘key-frame’, a history based fast detection process for each of the detection anchors in the primary subset is performed, where it is first determined whether a criterion for temporal based early exit is met and whether the detection anchor corresponds to a detected object and updating the detected object data structure according to detection results. Then for each of the detection anchors in each of one or more secondary subsets, it is first determined whether a criterion for spatial early exit is met and whether the detection anchor corresponds to a detected object, and updating the data structure according to detection results.

Abstract: A video processor includes a memory and a processor. The processor is coupled to memory and is configured to store in the memory (i) multiple raw frames belonging to a Group of Pictures (GOP) to be processed, and (ii) one or more reference frames. The processor is further configured to select for multiple target blocks having a same block-location in respective raw frames associated with a common reference frame, a common search region in the common reference frame, and before selecting another search region, to apply at least two motion estimation operations using at least two of the target blocks and the common search region, to estimate respective at least two Motion Vectors (MVs).
