Abstract: Data transforms suitable for transforming data, such as not necessarily limited to those suitable for transforming data from a spatial domain to a frequency domain, is contemplated. The data transforms may correspond with a discrete cosine transform (DCT), an inverse discrete cosine transform (IDCT), a discrete Fourier transform (DFT), an inverse DFT (IDFT), a modulated lapped transform (MLT), an inverse MLT, a modulated complex lapped transform (MCLT), an inverse MCLT, etc. where the corresponding basis functions are optimized depending on whether data being transformed is characterized as square and non-square.

Abstract translation: 预期适合于转换数据的数据变换，例如不一定限于适用于将数据从空间域变换到频域的数据变换。 数据变换可以对应于离散余弦变换（DCT），逆离散余弦变换（IDCT），离散傅里叶变换（DFT），反DFT（IDFT），调制重叠变换（MLT），反向MLT， 调制复合重叠变换（MCLT），反向MCLT等，其中相应的基函数根据被变换的数据是否被表征为正方形和非正方形来进行优化。
