Pseudo-random number sequences which using the form of elliptic curves can be generated efficiently in software or hardware by the same methods that are used for the implementation of elliptic curve (EC) public-key cryptosystems. In this paper, we proposed a secure image encryption scheme using key sequences generated from Chaos-Driven Elliptic Curve Pseudo-random Number Generator (C-D ECPRNG). This key sequences ... إقراء المزيد

Image-object extraction is one of the most important parts in the image processing. Object extraction is the technique of extracting objects from the pre-processed image in such a way that within–class similarity is maximized and between–class similarity is minimized. In this paper, a new method of extracting objects from grey scale static images using Fast Discrete Curvelet Transform (FDCT) via ... إقراء المزيد

This paper describes efficient object-based video coding schemes suitable for content-based multimedia streaming systems. Anew two video coding approaches are presented to study the effect of the object based motion estimation in video coding and the effect of the object based video coding on the compression quality, respectively. The first approach is based on a new motion estimation technique; based ... إقراء المزيد
