本文件将普通RGB图像转化成二值图像，方便后续处理(This document will be an ordinary RGB image into binary image, to facilitate follow-up treatment)

Quaternion library for inertial navigation system

contrast enhancement method is applicable for fog image

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

it is matlab code about buffer.it is very useful for electrical students . it is about how buffer works and its visulasation
