离散变换 meaning in English
discrete transform
Examples
- Currently , transforming coding is one of the most used approach for image coding , where the discrete cosine transform ( dct ) , the discrete wavelet transform ( dwt ) , and the lapped biorthogonal transform ( lbt ) are widely utilized . how to reduce the complexity of these discrete transforms , is the key technique to image compression . in this thesis , a type of lapped biorthogonal transform which can map integers to integers is considered
变换编码是图像压缩中的主流方法，其采用的主要变换有离散余弦变换、离散小波变换、双正交叠式变换，如何减少这些离散变换的计算复杂性，一直是图像压缩研究的重要课题。
