ARCHITECTURE FOR DUAL TREE COMPLEX WAVELET TRANSFORM

摘要

The present inventions disclose six level of decomposition using DTCWT, with each level comprising of 12 filter banks, each filter bank realized suing hybrid logic. Hybrid logic is design with combination of multiplexer based multiplier and distributive arithmetic algorithm. The distributive arithmetic algorithm is designed to improve throughput by 50%. The method comprises of pipelined stages for computing DTCWT, the DTCWT filters banks are reusable for computing inverse DTCWT. The 2D DTCWT is scalable and can operate on images of size ranging from N x N to N/32 x N/32. The method comprises of capturing two digital images from two different sources, six levels of decomposition is computed and from the sub bands appropriate ones are selected for image fusion.
