Using MATLAB, I designed and implemented a subband (wavelet) image coding system, building my own mini JPEG2000. By developing the encoder and decoder, optimizing PSNR and implementing user-defined ...

Subband coding is a technique that divides a signal into several frequency bands and compresses each band separately. This can reduce the bit rate and improve the quality of the signal.

Subband coding has become quite popular for the source encoding of speech. This paper presents a simple yet efficient extension of this concept to the source coding of images. We specify the ...
