在本文中，我们将比较数字滤波器与模拟滤波器，讨论各种数字滤波器架构，并通过一个范例一步一步说明如何设计FIR(非递归)滤波器。(The design of FIR filter )

matlab code for kmeans image segmentation

This paper presents a novel algorithm of hiding secret messages by applying mathematical lemmas and information theory. The proposed algorithm can hide more information with acceptable embedded rate and achieves requirements of information hiding algorithm and simply information extracting. The main idea is applying modern algebra to solve the information hiding problem in multimedia. In order to prevent some attacks on stganography, hidden initial bits of image data pixels are chosen randomly. The extracted information are achieved without the reference of the original image and extracted keys. The experiment results show that our approach is effective and reliable.
