This paper proposes a novel retinal vessel segmentatio n based on supervised method in color fundus images. To determine whether a pixel is the vessel pixel or not, 30 features are extracted for each pixel in the fundus image which consisting of features in Gaussian scale space, features by multi-scale Gabor filter and divergence of vector fields. Then we use the features obtained by the previous process to train the Support Vector Machine (SVM) Classifier. Finally, the image pixels are classified as vessels and non-vessels using a non-linear SVM Classifier. We report experimental results on a public retinal database DRIVE, demonstrated an outperformance in comparison with other supervised retinal vessel segmentation methods. It is suitable for computer aided diagnosis.

An on-demand weighed clustering algorithm is proposed against the limitation of wireless sensor network nodes with limited energy. This algorithm obtains more local network information by means of information interaction between nodes, and by comprehensively considering such factors as the current energy value, degree and transmission power, etc. of nodes, it makes different clustering decisions as per different application backgrounds of networks. Simulation results show that this algorithm has a more rational clustering by reducing energy consumption and lengthening network lifetime, compared to Low Energy Adaptive Clustering Hierarchy, a representative clustering algorithm.

This paper introduces the architecture of wireless sensor networks, compares several typical routing protocols of wireless sensor network, and focuses on the research of directed diffusion(DD) protocol and geograohic and energy aware routing(GEAR) protocol. GEAR selects the next hop nodes based on the neighbor node location information, limiting the information diffused in the network in the appropriate location of region, which can effectively reduce the maintaining routing information needed for overhead, and form the energy efficient data transmission path, to achieve the purpose of extending the life cycle of the network. Related research work provides the reference for the future network construction.
