在orl库上实现PCA，初学者的重要资料！(Important information in the the orl library PCA, beginners!)

In this project, Brain tumor in MRI is detected using image segmentation techniques. There are number of image segmentation techniques available but watershed segmentation is considered to be best among all. First of all prep-processing is to be done on MRI image followed by Segmentation. During pre-processing, MRI is first converted into gray scale image then salt and pepper noise is removed using median filter. Image is then enhanced using Histogram Equalization then Image segmentation is performed on image. In image segmentation, image is segmented into its constituent parts. In this way, brain tumor is detected.

无线传感器网络RSSI定位算法的研究与应用,提出了理论上的改进算法，并且有MATLAB实现，另外有硬件实现，具体是在MICA2上，基于tinyos操作系统，根据测得的RSSI值算出距离(RSSI location algorithm for wireless sensor networks for research and application, Tichu a theoretical 改进 algorithms and You MATLAB implementation, there are other hardware Shi Xian, Juti yes Zai MICA2 Shang, tinyos-based operating system, according to the measured RSSI Zhi calculated Juli)
