Wavelet Based Image Coding
Overview and Logistics
 Last Time:
– Transform coding
 Today:
– JPEG compression standard: Baseline block-DCT based algorithm
u lossy part: quantization with different step size for each coeff. Band
u lossless part: differential coding, run-length coding, Huffman
=> Continued with the class notes handed out in last lecture
– Subband and Wavelet based compression

ABSTRACT:
In this paper, we propose a simple and efficient technique for embedded color image coding. The proposed algorithm exploits inter- and intra-sub band correlations of the wavelet transformed luminance (Y) and chrominance (U and V) planes as well a ....etc

Abstract
This paper presents a sufficiently low bit rate Hi-Fi
audio coding technique with low computation designed
for transmitting real-time high-quality audio signal over
wireless channel. This technique applies wavelet packet
transform to decompose audio signal into subbands to
eliminate redundant data using spectral and temporal
masking properties. The encoded audio data is framed
with some critical field is protected by channel coding to
improve noise immunity when frames are transmitted
wirelessly. Experimental results s ....etc
