otsu s method used to find the threshold for bi-model histogram image.

contains Rectifier circuits for both single phase and three phase with various types of switches, pulse generator input remains same for all, an additional circuit with an active filter which can be used to reduce harmonics if the pulses are given by a paticular procedure.

面接触滑块润滑基于有限差分法，用于求解面接触滑块润滑的油膜厚度、油膜压力等(Lubricating surface contact with the slider based on the finite difference method for solving the contact surface of the slider lubrication film thickness, film stress, etc.)

用matlab实现的非线性动态范围调整算法，采用对数函数对图像进行增强，对低照度图像有一定效果(Nonlinear dynamic range adjustment algorithm matlab implementation, using a logarithmic function of image enhancement, image has a certain effect on the illumination)
