target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

this article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. it is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...

1 This paper gives an automatic method for online video stream styl2 ization, producing a temporally coherent output video stream. Our 3 system transforms video into an abstract style with large regions of 4 constant color and highlighted bold edges. Our system includes two 5 novel components. Firstly, to provide coherent and simplified out6 put, we segment frames, and use optical flow to propa...

e-Frame Lab Frame The LCLS, a Free-Electron Laser (FEL) designed for Operation at a first harmonic energy of 300 eV (A ~4081) in the Self-Amplified Spontaneous Emission (SASE) regime, will utilize electron bunches compressed down to durations of <OSps, or lengths of <150 cc. It is natural to inquire whether coherent radiation of this (and longer) wavelength will constitute a significant compone...

This thesis deals with the question of how to produce non-photorealistic stippling animations of 3Dmodels. Non-photorealistic animation techniques ought to take into account three important issues that arise when applying 2D drawing styles to 3D model rendering: frame-coherence, scalability and view-dependance, and rendition of animated models. To deal with these issues, the author proposes poi...

In this paper we propose an interpolation method to produce a sequence of plausible intermediate frames between two input images. The main feature of the proposed method is the handling of occlusions using a time coherent video segmentation into spatio-temporal regions. Occlusions and disocclusions are defined as points in a frame where a region ends or starts, respectively. Out of these points...

Flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. They have played an important role in understanding the physics of the coherent structures' formation and evolution in the transitional as well as the turbulent regions of the flow fields. Howev...
