Image Compression With Downsampling And Overlapped Transform At Low Bit Rates
This paper proposes an image coding method based on adaptive downsampling which not only uses the pixel redundancy but also considers visual redundancy. At the encoder side, codec...

An Algorithm for Low Memory Wavelet Image Compression
As wavelet-based image coding is set to become more widely used (e.g. with the completion of the JPEG2000 standard), memory efficiency for wavelet-based coding is becoming an incr...

Memory Architecture Exploration for Power-Efficient 2D-Discrete Wavelet Transform
The Discrete Wavelet Transform (DWT) forms the core of the JPEG2000 image compression algorithm. Since the JPEG2000 compression application is heavily data-intensive, the overall ...
