- Image processing is widely used in many fields,in image enhancement processing,traditional image enhancement method,such as histogram equalization, wavelet coefficient enhancement,and so on.Although these methods achieved good image enhancement performance,however,noise is amplified during image enhancement processing.In this paper,aiming at the problem,image enhancement algorithm based on dual tree complex wavelet transform(DT-CWT) is proposed.Firstly,image signal is decomposed by using DT-CWT,real tree and imaginary tree are obtained.And then the threshold processing of high frequency coefficients is performed.Finally,image signal is reconstructed by using DT-CWT.Experimental results show that the proposed method has better effect for image enhancement.
