(1) plotsmithchart.m
Usage:
(1) plotsmithchart(Zl,Zo)
Where Zl is the Load Impedence (possibly complex) and Zo is the Characteristic Line Impedence. Plots a smith chart, along with the reflection coefficient circle and the line of intersection with resistive component equal to 1.
(2) plotsmithchart
Without any parameters draws a blank smith chart. Wavelengths toward the generator are labeled around the perimeter.
Example calls:
(1) plotsmithchart(25,50)
Draws a smithchart,calculates and plots the reflection coefficient for a characteristic impedence of 50 ohms and a load impedence of 25 ohms.
(2) plotsmithchart(50+50j,75)
Same as (1) with a load impedence of 50+50j ohms.
(3) plotsmithchart
Plots a blank Smith Chart.

Description: 基于Matlab平台实现目标信息提取。求未含噪声的原图像的周长需先对图像进行二值化，然后选择一种算法进行边缘检测，包含prewitt,canny,sobel等算法，再通过sum(sum())函数进行周长的计算并显示在相应的位置。为求包含特定目标的噪声污染图像的周长或面积，首先对图像进行去噪，再进行二值化，接着进行微小分割，实现边缘提取或者区域分割，进一步统计目标周长或者目标面积。-Based on Matlab platform to achieve the goal of information extraction. Perimeter need to seek not contain the original noise image binarized image, and then select an algorithm for edge detection, including prewitt, canny, sobel algorithm, the circumference of the sum (sum ()) function calculated and displayed in the appropriate location. Seeking to contain a specific target image the perimeter or area of noise pollution, the first image noise, and then binarized, followed by small split, edge detection or region segmentation, and further statistical target circumference or target area.
