In lifting-based directional wavelet transforms, different subsampling patterns may show significant difference for directional signals in image coding. This paper investigates t...
Traditional 2D DCT implemented by separable 1D transform in horizontal and vertical directions does not take image orientation features in a local window into account. To improve ...
- In this report, we investigate the application of Direction Adaptive-Partitioned Block Transform (DA-PBT) to color images and propose a basic framework for DA-PBT Color Image Cod...

— This paper presents a novel 3-D direction aligned wavelet transform for scalable video coding. A new generalized 3D directional threading technique is seamlessly incorporated i...
Error correction codes of suitable redundancy are used for ensuring perfect data recovery in noisy channels. For iterative decoding based methods, the decoder needs to be initiali...
