A Specific Algorithm Based on Motion Direction Prediction
Complexity, Volume 2021, Issue 1, 2021., 2021 In this paper, we study the estimation of motion direction prediction for fast motion and propose a threshold‐based human target detection algorithm using motion vectors and other data as human target feature information. The motion vectors are partitioned into regions by normalization to form a motion vector field, which is then preprocessed, and then

Early CU Depth Decision and Reference Picture Selection for Low Complexity MV-HEVC [PDF]
Symmetry, 2019 The Multi-View extension of High Efficiency Video Coding (MV-HEVC) has improved the coding efficiency of multi-view videos, but this comes at the cost of the extra coding complexity of the MV-HEVC encoder. This coding complexity can be reduced by efficiently reducing time-consuming encoding operations. In this work, we propose two methods to reduce the

Video processing for panoramic streaming using HEVC and its scalable extensions [PDF]
, 2016 Panoramic streaming is a particular way of video streaming where an arbitrary Region-of-Interest (RoI) is transmitted from a high-spatial resolution video, i.e. a video covering a very “wide-angle” (much larger than the human field-of-view – e.g.
