In this paper, we present a scheme for embedding data in copies (color or monochrome) of predominantly text pages that may also contain color images or graphics. Embedding data im...
The quadtree data structure is widely used in digital image processing and computer graphics for modeling spatial segmentation of images and surfaces. A quadtree is a tree in whic...

Synthetic aperture radar SAR systems are mounted on airplanesand satellites, which have limited downlink and storage capacity, yet SAR image sequences may be produced at rates of ...
The vast majority of copied documents generally consist of text, and the copy quality mostly depends on the text's reproduction quality. A new technique to enhance dark text ...
The factorization method [1] is a feature-based approach to recover 3D rigid structure from motion. In [2], we extended their framework to recover a parametric description of the ...
Pseudo-semantic labeling represents a novel approach for automatic content description of video. This information can be used in the context of a video database to improve browsin...
This paper describes a computational method for estimating the body reflectance function of color surfaces. The experimental apparatus consists of a vision system having seven spe...
