wavelet basis的意思|示意

Then, it approximates the environment map in the same wavelet basis by keeping only the largest terms to get a non-linear approximation of the environment-map.

然后用相同的小波基对给定的环境光做小波变换，只保留其中绝对值较大的系数，从而得到环境光的非线性逼近。

Have analyzed properties of wavelet coefficients obtained from an image through wavelet transform, and discussed how to select wavelet basis to optimize wavelet coefficients.

分析了图像小波变换后小波系数的特征，讨论了优化小波系数的小波基选择问题。

By the family of wavelet basis function of wavelet Composition, it can describe the signal time (space) and frequency (scale) domain of the local characteristics.

小波由一族小波基函数构成，它可以描述信号时间(空间)和频率(尺度)域的局部特性。
