In view of the problem of big memory requirement and high computational complexity in the traditional wavelet transform algorithm

a hybrid line-based 7/5 lifting scheme wavelet transform algorithm is proposed. In the proposed algorithm

the line-based wavelet transform is used to reduce requirement of buffer in image compression

and the lifting scheme which is implemented by BT7/5 filter is used to reduce computation complex. The experimental results show that the proposed algorithm has similar the quality of compression with JPEG2000 and requires smaller memory than the traditional wavelet transform algorithm. Meanwhile

the proposed algorithm has lower computational complexity than the lines-based wavelet algorithm variant.
