hi this folder contains five matlab codes for gray level image histogram processing i hope that you will accept me in your site

使用matlab语言编程求解一维热传导方程(Using the matlab programming language for solving one dimensional heat conduction equation)

基于SVPWM的三电平逆变的matlab仿真，包含收发两个客户端的链路级通信程序,包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角。( Based on SVPWM three-level inverter matlab simulation, Contains two clients receive link-level communications program, It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle.)

编写离散时间傅里叶变换子函数，并调用此函数求下列序列的离散时间傅里叶变换(The preparation of discrete-time Fourier transform subroutine, and call this function find the following sequence of discrete-time Fourier transform)

摘　要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在 色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积 统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2 tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)
