- 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...

The power of sparse signal coding with learned overcomplete dictionaries has been demonstrated in a variety of applications and fields, from signal processing to statistical infe...
In this paper we propose the use of intra-frame prediction with lapped transforms for image coding. Both lapped transforms and intra prediction exploit the redundancies of neighbo...
The design of a class of wavelet filters and its application in Scalable Video Coding (SVC) is discussed in detail in this paper. The design method uses maximal flat wavelet filte...
In this paper, a lapped orthogonal transform adapted for local directionality of an image is proposed and its application in adaptive image coding is presented. First, we address ...
