A warning signal from the system which indicates high EC or EC ratio of a dairy cow is used to inform the milker to pay attention to the suspected cow. The detection thresholds of EC and ECR to determine whether a quarter or a dairy cow is infected with mastitis correspond with the criterion of SCC = 500×103 cells/ml for quarter foremilk of a dairy cow. The performance of online system for mastitis detection in dairy cows is evaluated with several methods, such as the detection thresholds, running analysis and discrimination analysis.

Firstly, DWT is applied to the image, and moment invariants is extracted on fixed-size blocks of low-frequency component in wavelet sub-band to yield a reduced dimension representation.

然而，许多实际情况是要求在不依赖任何预签名提取或预嵌入信息的前提下，对图像的真伪和来源进行鉴别，这就是图像盲取证技术，也叫被动取证技术，它是一种新的图像鉴别分析思路。

In this paper, a novel two-dimensional kernel maximum scatter difference discriminant analysis (2D-KMSDA) is developed for the extraction of nolinear feature by using the well-known "kernel trick". It extracts much more effective nolinear feature and made the true recognition rate raise saliently. What's more, it also offers a unified framework for two-dimensional nolinear discriminant analysis.

As a result, it is convenient for the recognition system to use the simple linear classifier to segment the sample space, so that the accuracy and distortion invariant ability can be easily achieved. The classification structure of a bifurcating tree is utilized to decompose the classification problem of multi-classes to the multi-stage classification of two classes, which simplifies the design of the classifier, and improves the searching efficiency as well. A gray-scale analysis based method for extracting features from optical correlation result is proposed.
