Some algorithms have been proposed but they still show some limitations. Recent approaches u Weighted pca regression to recover missing markers in human motion datased Principal Component Analysis (PCA) to create a single basis system from the unmissing frames in the motion sequence. However, we are aware that thWeighted pca regression to recover missing markers in human motion data
ose approaches of PCA have limitations in case of missing multiple gaps with a very long sequence. With the rising amount of Motion data, we question VIETNAM NATIONAL UNIVERSITY, HANOI UNIVERSITY OF ENGINEERING AND TECHNOLOGYKieu Hai DangWeighted PC A Regression To RecoverMissing Markers [n Human Mo Weighted pca regression to recover missing markers in human motion datant methods that could utilize the available Mocap dataset to enhance the performance of the current state-of-the-art algorithm. We first applied PCA into a collection of samples extracted from the Mocap dataset to gain a set of basis systems. Then, We further used least square method to compute a we Weighted pca regression to recover missing markers in human motion dataight vector for the basis systems. Finally, interpolation is the synthesis of the basis systems with their weight. To test the performance, we analyzeWeighted pca regression to recover missing markers in human motion data
