Directional motion-compensated spatio-temporal fuzzy filtering for quality enhancement of compressed video sequences
We propose a directional fuzzy lter to enhance the quality of compressed video sequences. A motion compensated spatiotemporal lter (MCSTF) is applied to intra-frame and inter-fram...

Directionality measurement and illumination estimation of 3D surface textures by using mojette transform
This paper presents a new approach to measure texture directions and estimate illumination tilt angle of 3D surface textures by using mojette transform. Feature vectors are genera...

Fast Scene Change Detection Using Direct Feature Extraction from MPEG Compressed Videos
In order to process video data efficiently, a video segmentation technique through scene change detection must be employed. Many of advanced video applications require manipulatio...

Good vibrations: Asymmetric vibrations for directional haptic cues
In this paper we present a new concept for haptic guidance in multiple dimensions, in the form of asymmetric vibrations. We show that by adding asymmetry, vibrations from a single...

Video denoising using 3-D Hybrid Wavelets and Directional filter banks
We propose a new family of nonredundant 3-D directional transforms that are useful for video signals. In our construction, taking into account the correlation amongst frames of vi...
