colour detection by wecam(color detection by wecam)

Image evaluation (mean, clarity, information entropy, standard deviation)

根据Richard.J.Cameron在论文综合N+2耦合矩阵的代码，主要的不同就是进行了去归一化，能够画出真实物理频率的频响曲线(Synthesis the N+2 coupled Matrix ,and which different from the former is thar I change the normalization frequency into reality frequency )

it is the modified header when simulate wireless mesh network in NS2

使用costas环实现载波同步，绘制出了载波频率跟踪曲线(Achieve carrier synchronization using the costas loop, draw the curve of the carrier frequency tracking)

a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery data and two bit Authentication data of the image block into the least significant bits (LSB) of its corresponding mapping block.The integrity of a test block is decided by comparing 2×2 non overlapping block of the test block with its corresponding mapping block. Experimental results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well as in tamper recovery of the image.
