宽带聚焦的目的是通过一个聚焦变换矩阵，使得对应于不同频段的数据变换成同一个中心频率的数据，从而形成相关矩阵。这里的关键就在于聚焦矩阵的选取，不同的选择对应于不同的算法。(Focus on the purpose of broadband are focused through a transformation matrix which corresponds to a different band with the data converted into a center frequency of the data, to form the correlation matrix. The key here is to focus on the matrix selected, different options correspond to different algorithms.)

EZW (Embedded Zerotrees of Wavelet Transforms) is a lossy image compression algorithm. At low bit rates (i.e. high compression ratios) most of the coefficients produced by a subband transform (such as the wavelet transform) will be zero, or very close to zero. This occurs because "real world" images tend to contain mostly low frequency information (highly correlated). However where high frequency information does occur (such as edges in the image) this is particularly important in terms of human perception of the image quality, and thus must be represented accurately in any high quality coding scheme.
