Abstract: Provided are a method and an apparatus for implementing batch extraction of human anatomical feature parameters. The method includes: obtaining a to-be-measured sample; generating an average model; calculating a point correspondence of a spatial location formed by the average model and each to-be-measured sample; measuring each to-be-measured sample on the average model; and outputting feature parameter data of each to-be-measured sample in batch. Calculation time is reduced by combining feature point extraction with affine transformation, and corresponding points are calculated through a non-rigid registration method to achieve batch and quick measurement.

Abstract: Provided are a method and apparatus for evaluating anatomical adaptation of an implantable orthopedic medical device. The method includes: obtaining an anatomical adaptation region of a to-be-evaluated bone with the implantable orthopedic medical device; determining a baseline of the anatomical adaptation region and a baseline of the implantable orthopedic medical device for position registration, and conducting the position registration for the anatomical adaptation region and the implantable orthopedic medical device based on the baselines; and evaluating adhesion of the to-be-evaluated bone to the implantable orthopedic medical device by calculating a distance from each point on an inner curved surface of the implantable orthopedic medical device to the anatomical adaptation region.

Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.

Abstract: The present disclosure provides a distortion-free boundary extension method for online wavelet denoising. The method includes: S1: acquiring a signal segment xn, and performing a distortion-free boundary extension on the signal segment to obtain M+N+L data; S2: decomposing a lifting wavelet of the N data to be denoised into j layers to acquire approximation coefficients and detail coefficients; S3: calculating a threshold of each layer of the lifting wavelet; S4: thresholding the detail coefficients of each layer to obtain estimated values of the detail coefficients; S5: performing wavelet reconstruction by the approximation coefficients and the estimated values of the detail coefficients obtained by thresholding to obtain a reconstructed signal after denoising; and S6: outputting data.
