Abstract EN

This paper introduces, firstly, a proposed method of computing one and two-dimensional wavelet transform .

The proposed method reduces heavily processing time for decomposition of image keeping or overcoming the quality of reconstructed images.

Also, the inverse procedures of all the transformations for multi- dimensional cases verified.

Secondly, computes quantization and run length encoder.

Different types of quantization are presented in this paper with effects of these differences on Compression Ratio (CR).

Thirdly, compute PSNR, RMSE, CR, and size.

The effect noted this difference in levels of FLWT on same picture, where PSNR, MSRE, SIZE, and CR different from one level to another.
