%X In order to improve the recognition rate of image characteristic,an image characteristic recognition system based on Q-shift dual tree complex wavelet transformation algorithm is studied and designed.The advantages of com- plex wavelet are reserved in this design.It satisfies the entire reconstruction conditions and has favourable symmetry. The image of downy mildew of cucumber is used as experiment sample.The training and learning simulation experi- ments are done on Visual C++ software platform.The result...
