图像清晰度评价指标Matlab
图像清晰度评价函数说明
1、熵: 表示图像所包含的平均信息量的多少,嫡值越大则所含信息量越多。
文件名：entropy.m 结果：EN
2、交叉嫡：反映两幅图像的差异,交叉嫡越小,则融合图像和原图像的差别越小。
文件名：cross_entropy.m 结果：平均交叉嫡MCE，均方根交叉嫡RCE
3、峰值信噪比: PSNR越高,说明融合效果与质量越好。
文件名：psnr.m 结果：PSNR
4、Qabf: 评价边缘或梯度质量，越大边缘越明显
文件名：Qabf.m 结果：Qabf（QAB/F)
5、平均梯度（Average Gradient）:也称为清晰度，反映了图像中的微小细节反差与纹理变化特征，同时也反映了图像的清晰度，越大越好。
文件名：avg_gradient 调用：outval = avg_gradient(img)
6、结构相似性指数： SSIM指原图像和融合图像的相似程度,值越大越相似
文件名：ssim.m 结果：SSIM
7、互信息：MI(mutual information)
8、NMI: Normalized mutual information(Image sharpness evaluation function)

TRAOD_Algorithm
基于轨迹划分的异常轨迹检测方法。首先采用两种分段粒度将每条轨迹分为若干子轨迹线段，然后，在基于距离的异常检测方法的基础上，引入调整系数的概念，采用密度与距离相结合的方法进行异常轨迹检测。
(Abnormal trajectory detection method based on trajectory partition.Firstly each trajectories should be divided into several substrajectories using two granularities. Then the notion of adjustment coefficient is introduced on the basis of distance based anomaly detection method, and the abnormal trajectories are detected combining density and distance.
