A Panorama on Multiscale Geometric Representations, Intertwining Spatial, Directional and Frequency Selectivity
The richness of natural images makes the quest for optimal representations in image processing and computer vision challenging. The latter observation has not prevented the design...

Image interpolation with directionlets
We present a novel directionally adaptive image interpolation based on a multiple-direction wavelet transform, called directionlets. The algorithm uses directionlets to efficient...

Learning to Track: Conceptual Manifold Map for Closed-Form Tracking
Our objective is to model the visual manifold of object appearance corresponding to geometric transformation. We learn a generative model for object appearance where the appearanc...

Adaptive Spline-Wavelet Image Encoding and Real-Time Synthesis
A wavelet-based image-encoding is described which, when used in conjunction with the Di erence Engine (a customdesigned VLSI display processor) allows us to reconstruct an image i...

Proximity sensing with wavelet-generated video
In this paper we introduce wavelet video processing of proximity sensor signals. Proximity sensing is required for a wide range of military and commercial applications, including w...
