用两种向量化和一种循环的思路计算水仙花数，并给出所需时间比较 水仙花数是指一个三位数,其各个数的立方和等于该数(Quantified in two and a loop to the idea of calculating the number of daffodils and narcissus are given the time required for comparison is a three-digit number, the individual cubes, and equal to the number of)

改进的分水岭算法，实现了分水岭变换，能很好的抑制过分割现象，初学者可以做参考。(Improved watershed algorithm and watershed transformation and inhibition of over-segmentation, a beginner can do a reference.)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)
