Abstract
This paper proposes architecture for IDWT (Inverse Discrete Wavelet Transform) in spatial domain. The architecture is based on MATLAB results of IDWT. The reconstruction of compressed image has been done using fixed point, floating point methods & standard IDWT function in MATLAB. The comparison between results was made based on standards like SNR (Signal to Noise Ratio), MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio).
