The most interesting dissimilarity between these two kinds of transforms is that individual wavelet functions are localized in space.Fourier sine and cosine functions are not.This localization feature,along with wavelets' localization of frequency,makes many functions and operators using wavelets "sparse" when transformed into the wavelet domain.This sparseness,in turn,results in a number of useful applications such as data compression,detecting features in images,and removing noise from time series.

这两类变换的最有趣的差异是小波函数各自在空间局域化（我想如果你对小波的原理有一定了解就会明白局域化的意思,所以就不在这里作注解了）,而傅里叶正弦和余弦函数则不是.该局域化特性以及小波的频率的局域化,使得很多采用小波的函数和运算子在变换至小波域的时候,都变得“稀疏”.该稀疏（给小波）带来很多有用的应用,比如数据压缩,图像特征检测,时序去噪.
in turn不是轮流和依次的意思,而是as a result of something.
