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 . (This program compress and recostruct using wavelets.

The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high
conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum
Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion
system. The generator considered is a wound rotor induction machine whose stator is connected directly
to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator
flux-oriented vector control is applied to control the active and reactive current loops independently. The
MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control
solution aims at driving the position of the operating point near to optimality. This is a very important
aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD
program which is interfaced with the Real Time Digital Simulator (RTDS).
