Algorithms of contour segmentation and pattern recognition for computer vision systems

A Review of Computer Vision Segmentation Algorithms

1 Introduction The remote sensing and computer vision communities share a common goal of extracting useful information from raw imagery. Both communities have exploited several trends that support the increasingly timely, cost effective, accurate, and effective automated extraction of information from raw imagery that include increasingly powerful, affordable, and available computer hardware; i...

Human Computer Interaction Using Vision-Based Hand Gesture Recognition

With the rapid emergence of 3D applications and virtual environments in computer systems; the need for a new type of interaction device arises. This is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. In other words, evolution of user interfaces shapes the change in the Human-Computer Interaction (HCI). In...

Convexity Analysis of Active Contour Problems - Computer Vision and Pattern Recognition, 1996. Proceedings CVPR '96, 1996 IEEE Computer Society Co

A general active contour formulation is considered and a convexity analysis of its energy function ispresented. Conditions under which this formulation has a unique solution are derived; these conditions involve both the active contour energy potential and the regularization parameters. This analysis is then applied to four particular active contour formulations, revealing important characteris...
