经典的k均值聚类算法，用于无监督学习和数据分类，广泛应用于数据处理和模式识别领域(Classical k-means clustering algorithm for unsupervised learning and data classification, widely used in data processing and pattern recognition)

对随机序列进行（7,4）汉明码编码，经过bpsk调制解调，然后译码，最后绘出信噪比与误码率的关系曲线(Random sequences (7,4) hamming code encoding, after bpsk modem, and then decoding, and finally draw the signal to noise ratio and bit error rate curve)

Code to create bessel function in 2D. Arguments are: rad - radius amp - amplitude sat - saturation level (0 to 1) x, y - image dimensions

Make the Huffman-tree from the lengths of the Huffman codes. The Huffman codes are also needed, and if they are known, they can be given as an extra input argument.

可以将整幅图像分割成大小均一化的子图像，并将每幅子图像分割成单独的图像(Whole image can be divided into sub-image size of homogenization, and each piece of sub-image is divided into separate images)
