常规的中值滤波器,在噪声的密度不是很大的情况下效果不错。但是当概率出现的概率较高时,常规的中值滤波处理后,仍然具有噪声点,并丢失了细节和边缘,效果不是很好。
自适应中值滤波器可以尽可能的保护图像中细节信息,避免图像边缘的细化或者粗化。(The conventional median filter works well when the noise density is not very large. However, when the probability of probability is high, the conventional median filter still has noise points, and the details and edges are missing. The result is not very good.
The adaptive median filter can protect details in the image as far as possible and avoid thinning or coarsening of the image edges.)

特征选择之relief-F的MATLAB实现
Relief-F 算法是由 Kononenko 在 Relief 算法基础上扩展得到的,可以用来解决多分类与回归问题。 Relief-F 特征选择算法利用特征与类别间的相关程度判别特征的敏感程度,敏感的特征能使同类样本靠近,非同类样本远离。基本思想是: 先随机从总样本集 D中获取一个样本 R, 然后在 与 R 同类样本集中和与R 异类 样 本 集 中 各 获 取 k 个近 邻 样 本, 在 特 征 集 F中如果某个特征上异类样本的距离大于同类样本,则这个特征是有利于分类的,增加其权重,重复 n 次 取所有结果的均值作为每个特征的最终权重值.

Regularized_Newton_Residual_algorithm
一种使用牛顿迭代的超分辨算法,该算法以2的对数提高传统Landweber算法的运算速度,附带文章。(The problem of poor resolution of acquired image in the passive millimeter wave imaging stems mainly from antenna size limitations, thus necessitating efficient post-processing to achieve resolution improvements. A novel image super-resolution algorithm, Regularized-Newton-Residual (RNR) algorithm, is proposed for Passive Millimeter wave imaging (PMMW). First Newton inversion algorithm is introduced into the field of image restoration. The iterative scheme of Newton algorithm is deduced based on normal equation. Then, residual method is employed to achieve better performance and implement spectrum extrapolation. Experimental results demonstrate the algorithm is insensitive to noise distribution. Furthermore it has high super-resolution rate and fast convergence speed. )

SHAKE_PROOF
手持式摄像机在使用时常常会受到使用者有意无意抖动的影响,从而影响成像效果,造成录制视频的不稳定及跳动问题,尤其是在使用者在一场景中特写或者跟踪某一具体目标时,使用者通常不能准确定位到或者估计出运动目标的位置,从而造成目标在视频中位置的不稳定,造成视频的主观效果变得不理想。
为了解决这一问题,我们需要设计一种算法来识别这种无意义的运动并设法通过补偿的方式来使得场景中的目标物体保持位置稳定的状态。
手持式摄像机捕获的视频通常都会受到抖动的影响,这严重的影响视频的主观效果。
这里提出的算法可以可靠的用于数字视频的去抖动。这个算法通过识别这些意外的抖动并且利用运动补偿的方法来获得一个较好的视频输出。
这个系统可以分为三个模块:(1)运动估计模块;(2)抖动识别模块;(3)运动补偿模块。
注:代码在matlab 7.7.0(R2008b)运行通过

Digital image stabilization by adaptive block motion vectors filtering, IEEE Transactions on Consumer Electronics, 2002(Handheld cameras are often used by the user intentionally or unintentionally, the influence of jitter affect the imaging results, resulting in instability and beat the problem of recording video, and especially in the user in a scene close-up or tracking a specific target,users often can not accurately navigate to estimate the location of the moving target, resulting in the subjective effects of target location of the instability in the video, resulting in video not ideal.
In order to solve this problem, we need to design an algorithm to identify such a meaningless exercise and try to make the object in the scene to keep the position stable state by way of compensation.
The handheld camera captured video usually subject to the influence of jitter, the subjective effect of which seriously affect the video.
The algorithm proposed here can be reliably used for digital video to jitter. This algorithm by identifying the jitter of these accidents and the use of motion compensation m)
