IMAGE COMPRESSION USING DCTWT & N-LEVEL-HYBRID TECHNIQUE
Journal Title: Indian Journal of Computer Science and Engineering - Year 2015, Vol 6, Issue 1
Abstract
As per the current position, the collective growing of knowledge and the arrival into the numerical age, we have to grip a huge quantity of info each period which frequently grants problems. So, the numeral info must be kept and recovered in an effectual and real method, in instruction for it to be place to applied custom. Compressing an image is meaningfully dissimilar than compressing fresh binary data. General resolution compression packages can be used to compress images, but the consequence is less than best. In this paper, an original system that indicates the Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT) and Nlevel hybrid DCTWT technique proposed. DCT has high energy compaction stuff and requires less computational capitals. On the additional pointer, DWT is multi-resolution transformation.
