Developed Softwares
• Solid Modeling (∼4000 lines): An Interactive Modeling, Animation and Rendering tool for 3D
Objects (cf. http://www-rocq.inria.fr/∼sahbi/Web/Memoire.html) conceived at the INI-institute,
Algiers, Algeria.
• Machine Learning (6360 lines): Package for quadratic programming using the interior point,
SVM training, regression, kernel PCA, kernel Fisher discriminant analysis conceived at INRIA,
France. KPCA and SVM softwares have been used in both the SAGEM and the priam MEDIAWORKS projects.
• Face Detection (15604 lines): A coarse-to-fine real time face detection software conceived and
evaluated at INRIA, France. This software has been used in the priam MEDIAWORKS project
for video annotation. It processes 5 frames per second.
• Face Recognition :
1. Dynamic space warping (1413 lines): a tool for face recognition based on the estimation of
a deformation pseudo-distance between two face images. This software has been used in
the priam MEDIAWORKS project for video annotation.
2. Face indexing (4112 lines): software for computing face signatures including entropy facial features, eigenfaces (with the kernelized version), Fisherfaces and wavelets (Haar and
Daubechies). This software has been used in the SAGEM industrial project.
3. The two previous tools have been integrated in the IKONA system for image retrieval (cf.
http://www-rocq.inria.fr/cgi-bin/imedia/ikona).
• Parallel programming using the PVM platform (1235 lines): A software for face detection
was developed at INRIA using Parallel Virtual Machine (PVM). The underlying master-slave
platform handles a cluster of computers (8 linux PCs in practice) and makes it possible to process
a scene with a high speed up factor proportional to the number of computers in the cluster.
