求信噪比的MATLAB源代码 很实用的函数(Signal to noise ratio for the MATLAB source code is very useful function)

ACE算法 对图像进行增强，能完成对雾天图像，低照度图像的增强处理(automatic colour enhance)

利用非线性结构张量处理一些图形问题，能够有效的解决和优化现成的处理方法(In this article, we introduce nonlinear versions of the popular structure tensor, also known as second moment matrix. These nonlinear structure tensors replace the Gaussian smoothing of the classical structure tensor by discontinuity-preserving nonlinear diffusions)

说明：  内含多种图像去噪的方法，包括高斯，椒盐噪声等问题(Contains a variety of image denoising methods, including Gaussian, salt and pepper noise and other issues)

区域生长法的图像分割，可以较好地提取脑部图像。(The region growing method can extract brain image well.)

说明：  雷达模拟LFM脉冲信号，模拟目标回波（目标距离50km，速度100m/s）和噪声信号（信噪比）(Radar simulated LFM pulse signal, simulated target echo (target distance 50km, speed 100M / s) and noise signal (signal-to-noise ratio))

改进的水平集方法，采用C_V模型进化。为多相位(improve the level set method, C_V evolutionary model. For the multi-phase)

里面包含kalman，扩展kalman，无迹kalman，粒子滤波，无迹粒子滤波等源码的实现。(upf--The Unscented Particle Filter )

高斯平滑滤波的matlab程序，对于初学者很有帮助(Gaussian smoothing filter matlab program, useful for beginners)

此程序计算的是两幅图像的峰值信噪比，运行流畅(This program calculates the peak signal to noise ratio of the two images, run smoothly)
