Abstract

Integer based-matrix algorithms for discrete Haar transform and discrete wavelet transform are proposed with relation to the multiresolution representation. A recursive wavelet transform technique is used with a view to demonstrating simply lossy reconstructed images in contrast to an original image under the specified resolution size. A visual effect of reconstructed images with different appearance and image quality, caused by modifying or throwing away a part of the 2D evaluation such as similarity and/or modified similarity, and fidelity: RMSE and/or PSNR.
