comparisions of texture and colour features for image retrival

实现双边带抑制载波调幅信号的时域波形和频域波形的仿真，采样点数默认为2^18。(achieve bilateral suppression of carrier signal amplitude of the time-domain and frequency-domain waveform simulation, The default sampling point to 2 ^ 18.)

说明：  数字信号的产生和DTFT运算，及各种图形的比较(Digital signal generation and DTFT computation)

说明：  统计中的COSSO方法,一种很有效的方法(cosso with adaptive models)

恢复清晰图像的一种方法，达到了比较好的效果。(A way to restore a clear image, reached a relatively good results.)

FFT变换以及IFFT变换 基于matlab编程 (Based on the FFT and IFFT transform matlab programming)

人工加入椒盐噪声，进行中值滤波去噪,可以自己加入不同密度的椒盐(Artificial adding salt and pepper noise, median filtering denoising, you can add your own salt and pepper different densities)

粒子群代码,是一个简单的例子群算法，maltab。可以根据需要进行修改，亲测过可以运行(Particle swarm code)

KDE for segmentation such as how to locate the person from the envrionment(KDE for segmentation)

this is a program code for rotation using GUI
