1.      Facial image metamorphosis animation:

 

Image metamorphosis is a technique for creating a smooth transition between two given images. It plays an important role in a wide range of applications including remote sensing, medical imaging, and machine vision as well as in computer graphics. The problem in image metamorphosis is how to generate an in-between image from two given images and establish the correspondence between the features of them. I addressed such a challenge by proposing an optimization facial image metamorphosis algorithm for generating smooth in-between images. The proposed algorithm generates a smooth warp that reflects feature point correspondences and has a contribution in different applied areas like the interpolation of intermediate planar slices in medical data sets.

 

2.      Facial caricaturing animation:

 

The art of facial caricaturing is one of the most challenging tasks in computer graphics and other applied areas requiring modeling and rendering not only of face geometry but also of distinctive facial features.  For this application, I propose a new algorithm for implementing the theory of facial caricaturing as an automatic computer generator based on face anthropometrical theory.

 

3.      Human skin aging animation:

 

Reproducing visual aging effects by computer is a difficult and time-consuming   task because of the individual shape of the face and the subtle and spatially varying reflectance properties of skin. For this application, a novel facial animation algorithm has been proposed with three techniques based on researches specialized on the human texture perception, bi-directional reflectance distribution function BRDF and the multi-resolution analysis of wavelets.

The proposed algorithm has a contribution in different applied areas like multimedia titles, virtual reality VR systems, interactive games and criminal objects such as finding murders after number of years. 

 

4.      Subdivision surfaces for Modeling and Animation

 

Subdivision surfaces are rapidly gaining popularity in computer graphics, modeling, simulation, movie character creation and human character animation.  The problem with the subdivision algorithms is that after few subdivision steps, a number of generated meshes will become huge and the number of faces grows exponentially, consequently difficult to manipulate. Due to memory and time restrictions, the number of subdivision steps that can be performed is relatively small. I addressed such problems by proposing new algorithms as a key solution for such a challenge. The objective of the proposed technique is to reduce the huge number of the generated meshes and to manage the exponential growth of the number of new polygons created during the subdivision process.

 

5.      Fractal Geometry, Graphics Design, Arts and Photo-Realistic Rendering

 

Within the last ten years fractal geometry and its concepts have become central tools in most of natural sciences and engineering such as medical imaging, biology, geology, physiology, earth science, etc. Some mathematicians and computer scientists have used fractal geometry to generate study and analyze complex 2D images, while 3D extensions are still aspiring goals and challenging tasks. An extension algorithm for visualizing 3D fractal patterns is proposed. The proposed algorithm makes rendering 3D fractal patterns reliable for interactive machines and has potential to be practically useful tool for graphics applications.

 

6.      Multimedia and Broadcasting Applications

With rapid progress in communications technology led by the Internet and in the field of broadcasting centered on digital media broadcasting, users can now enjoy a variety of contents and media such as:

·         Web pages, E-mail, Mobile phone, Networked games,

·         Video conferencing which is done between two especially set-up rooms. In each room, one or more cameras are used, and the images are displayed on one or more monitors,

·         Interactive TV and video to the home which allow viewers to select, interact with and control video play on a TV set in real time,

·         Distance learning in which education takes place through a combination of stored multimedia presentations and participation of the students in which not all of them are in the same place during a class,  

·         Movies on demand in which a viewer can select from a large library of videos and then play, stop, or reposition the tape or change the speed,

·         Media enrichment which indicates the technology for converting various media contents such as text, voice, dynamic images, etc. to another media like Web pages to TV program, TV program to comics, and from chat data to other,

·         Virtual Reality which provides very realistic effect through sight and sound, which allowing the user to interact with the virtual world,

·         Digital interactive storytelling,

My research is focuses on studying and analyzing the principle theory underlying such different media topics and performs them practically. Therefore, we have to consider the following factors:

·         Make user more effective in their information or communication task.

·         Reducing learning time.

·         Speeding performance.

·         Facilitating retention.

·         Increasing subjective satisfaction.
