说明：  通过OpenGL实现一个简单的海洋模拟，不涉及光照。(A simple solution for ocean simulation)

EM算法。问题背景是，有N条长为L的DNA序列，每条序列里面有一条长尾K的目标序列，但不知道他的位置，目标序列内的核苷酸服从foreground product multinomial distribution，非目标序列服从background multinomial distribution，改程序意在求解两种分布的参数。(EM algorithm. Background to the issue is that there are N pieces of length L of DNA sequences, each sequence which has a target sequence Nagao K, but do not know his position, the target nucleotide sequence within obedience foreground product multinomial distribution, non-target sequence obey background multinomial distribution, the program is intended to change the parameters in solving the two distributions.)

基于DCT变换的图像压缩matlab实现（附测试图）(DCT-based image compression transform matlab realize (with the test chart))

说明：  计算图像直方图的统计特征，包括均值，方差，熵，三阶矩等。(image histogram calculated the statistical characteristics, including mean, variance, entropy, such as third-order moments.)

改进的LEE，FROST，KUAN滤波，适合于任何图像滤波，可作为参考滤波比较()

说明：  用matlab语言实现的图像平滑算法，效果较好，可设置不同的参数得到不同的平滑效果(Matlab language used to achieve the image smoothing algorithm, the effect is better, you can set different parameters of the smoothing effect of different)

数字图象处理算法的演示，包括：图象的DFT和逆DFT，图象的FFT和逆FFT，在图象中加入正弦噪声，图象的模板运算实现图象平滑和锐化等等。(digital image processing algorithms demo, including : Image DFT and inverse DFT, FFT image and inverse FFT, in the image by adding sinusoidal noise, the template image Operational Image sharpening and smoothing and so on.)

加权中值滤波,用于图像增强,只用于超声图像,对超声图像去噪有很好的效果(Weighted median filter is used for image enhancement, only for ultrasonic image, has the very good effect on the ultrasonic image denoising)
