Description: Based on the real number of binary notation, the CDF (Cohen, Daubechies and Feauveau) 9/7 Biorthogonal wavelet enhancement factor into the binary, using a simple shift operation in place of one plus the complex structure of floating-point multiplier, in order to achieve the JPEG2000 9/7 discrete wavelet transform the fixed-point calculation. Compared with the floating-point calculations, shift operation of one plus the biggest advantages is the calculation is simple, especially vulnerable to the realization of ultra-large-scale integrated circuits, making real-time image processing hardware signal possible
