ANALYSIS OF WAVELETS USED IN COMPRESSED SENSING FOR IMAGE COMPRESSION

Wavelet analysis has engrossed more researchers in the field because of its analyzing ability for fastly solving and altering transient signals. Wavelet investigates its capability to analyze locally i.e. localized area can be analyzed for any larger signal. Wavelet analysis is can reveal data aspects which other techniques for image analysis may fail to notice aspects such as tendency, discontinuities of higher derivatives, breakdown points, and self-similarity.

Wavelet Theory has significance in image analysis, signal processing, transient signal analysis, communication systems. Also wavelet has captivated interest of researchers in active area of signal processing, data compression, harmonic analysis, operator theory, fractals and quantum field theory. The wavelet transform for de-noise the color image signal is noteworthy footstep in handling noise. Wavelet employed for de-noising can be executed with no smoothing of sharp structures. Wavelet transform provides more stability in reconstruction of true color image signal. This paper presents the performance of DWT algorithms for compressing color image.
