SAMSUNG’s S3C2440A is
designed to provide hand-held devices and general applications with low-power, and high-performance microcontroller
solution in small die size. To reduce total system cost, the S3C2440A includes the following components.
This document contains a specification for a new low pin count bus interface, dubbed LPC, that will be added to
future Intel chip-sets. The target audience for this document are system and component designers.
This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture quality),
bit ratio etc. To get pq install pqs function .
