Two-dimensional signals are normally processed as rectangularly sampled arrays; i.e., they are periodically sampled in each of two orthogonal independent variables. Another form...
This paper proposes a framework for segmenting different textured areas over synthetic or real textured frames by curves propagation. We assume that the system has the ability t...
Consider classes of signals that have a finite number of degrees of freedom per unit of time and call this number the rate of innovation. Examples of signals with a finite rate ...
We present methods of estimating displacements of moving objects from one frame to the next in a television scene and using such displacements for frame-to-frame prediction. Dis...
Recently a rapid imaging method was proposed [1] that exploits the fact that sparse or compressible signals, such as MR images, 3D randomly under-sampled Cartesian trajectory ca...
