discrete transform meaning in Chinese

离散变换

The data processing system further includes a discrete transforming means for performing a discrete transform on the input data at the first sampled frequency for trans forming the input data to a discrete function in a second - variable - domain at the first sampling frequency
此资料处理系统也包含一个离散转换装置，用来对以第一个取样频率所取样的输入资料作离散转换，也就是将输入资料转换成以第二个取样频率为频率及第二个变数为定义领域的离散函数。
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。
