New Image Enhancement Method Based on Multi-wavelet Transform
Wavelet analysis is the latest international wide time-frequency analysis tool,which is the most powerful tool for image de-nosing.Through wavelet transform can separate signals into the different distinct block signal which have the same frequency.Multi-wavelet has some very important properties such as orthogonality,symmetry,and short support,which makes up for the shortcoming of scalar wavelet.Propose a new image enhancement method which based on.multi-wavelet transform.Carry on the different enhancement with the change of multi-scale.The results show that the new method can obtains high enhancement effect.
