TheUnscentedParticleFilter

High Accuracy Time Delay Measurements

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

人脸检测是人脸识别的重要组成，由于肤色具有相对稳定性切在恩踩空间上有一定的类聚性，基于肤色的人脸检测能够提高检测的准确性(Using skin color model image for testing, to determine the amount of the face region. Color with class cohesion in the color space can improve the efficiency of detection)
