edge detection using gabbis

这是一个SUSAN算法实现, 对图像处理中的边,角等特征保留和图像降噪方面有着重要的应用(SUSAN This is an algorithm for image processing side, angle and other characteristics of the retention and image denoising has important applications)

A signal is transmitted using a carrier frequency of 900 MHz. It is transmitted through a multipath channel which can be modelled as Rayleigh fading. Assumingthe Dopper spread as 10Hz and the number of multipaths as 10, generate the Rayleigh faded signal. Compute the outage rate (the probability of the signal falls below certain rate, say ?10 dB) of the signal. Using MATLAB, demonstrate the path loss as a function of loss parameter for distances ranging from 2 km to 40 km. Calculate the power loss in dB

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

This function is the function for the closed contour plot of the swing, then swing the plot padding made before the action, so the plot can take into account the entire swing closed contour, the program I used curvature scale space of his treatment another program curvature is used to calculate the location of high curvature points

here is a code for text to image compression. you can convert your .txt file to jpeg image
