    Abstract: There is provided a computerized method and system of controlling a video content system based on an input video bitstream, the input video bitstream including encoded data encoded from one or more input frames of a video sequence, the method comprising: extracting, from the input video bitstream, encoding information associated with each input frame of said one or more input frames, the encoding information being used in an encoding process of the input frame to encode pixels included in the input frame into corresponding section of the input video bitstream; calculating one or more intricateness values each for a respective input frame based on the encoding information associated therewith, each intricateness value being indicative of encoding difficulty of the respective input frame in the encoding process; and providing a configuration instruction for controlling a video content system by using the one or more intricateness values.

    Abstract: A method, comprising obtaining a first plurality of decode-independent segments corresponding to an original video bit-stream, re-encoding each one of the first plurality of decode-independent segments according to a quality criterion, giving rise to a second plurality of decode-independent segments; and generating an output video bitstream comprising a third plurality of decode-independent segments, wherein each segment in the third plurality of decode-independent segments is selected from either the first plurality of decode-independent segments or from the second plurality of decode-independent segments using a selection criterion that is related at least to a segment's bit-rate.

    Abstract translation: 一种方法，包括获得与原始视频比特流相对应的第一多个解码独立片段，根据质量标准对所述第一多个解码独立片段中的每一个进行重新编码，从而产生第二多个解码 独立细分; 以及生成包括第三多个解码独立片段的输出视频比特流，其中所述第三多个解码独立片段中的每个片段从所述第一多个解码独立片段中或从所述第二多个解码独立片段中选择 使用至少与段的比特率相关的选择标准。

    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: There are provided computerized systems and methods for video quality assessment, the system including a server including a database configured to store pointers to a plurality of video clip pairs and a processor operatively connected thereto, configured to store pointers to a plurality of video clip pairs to be used in one or more test sessions performed by one or more users. The processor is configured to create, for each test session performed by a respective user: a test set, a display order and display positions of the each video in each video clip pairs in the set, and is further configured to send the one or more test sets to the one or more users for assessing quality and to receive feedback regarding the assessed quality, wherein the feedback is usable for providing subjective quality evaluation of the plurality of video clip pairs.
