说明：  特征检测，Loy and Zelinski s fast radial feature detector.(Loy and Zelinski s fast radial feature detector.)

说明：  Converting an image into blocks of 8 x 8 and apply DCT on any one of the blocks

零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)

Matlab多级非线性加权平均中值滤波算法代码，能解决一般的问题(Matlab nonlinear weighted average multi-level median filtering algorithm code, can solve the general problem)

说明：  matlab有关绘图命令介绍资料，希望给大家带来帮助。(Matlab orders about drawing introduced material, hope to bring you help.)

粒子图像分割及匹配均为自行编制的子例程，详细画出了时域和频域的相关图，采用的是脉冲对消法。( Particle image segmentation and matching subroutines themselves are prepared, Correlation diagram shown in detail the time domain and frequency domain, It uses a pulse of consumer law.)

A simple ASK, PSK and FSK codings

说明：  matlab实现几类简单机器学习算法，具有注解，易于理解(Matlab implements several types of simple machine learning algorithms, with annotations, easy to understand)

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.
