optic disc localisation using L1 minimisation algorithm

As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.

LDA线性判别分析是一种经典的提取特征的算法，它的基本思想是通过样本的类内离散度和类间离散度，寻找由最佳投影矢量构成的投影矩阵。将原始的样本数据投影到特征子空间中，实现数据分类。由于在人脸识别时常常会遇到小样本问题，因此在本次代码中，先用PCA主成分分析的方法降低样本维数，再用线性判别分析提取特征。最后，使用最小距离分类器判别分类，得到一个投影维度和识别率的曲线图。
