Mean Oriented Riesz Features for Micro Expression Classification

Carlos Arango Duque, Olivier Alata, Rémi Emonet +2

Micro-expressions are brief and subtle facial expressions that go on and off the face in a fraction of a second. This kind of facial expressions usually occurs in high stake situat…

Wavelet-based Reflection Symmetry Detection via Textural and Color Histograms

Mohamed Elawady, Christophe Ducottet, Olivier Alata +2

Symmetry is one of the significant visual properties inside an image plane, to identify the geometrically balanced structures through real-world objects. Existing symmetry detectio…

Multiple Reflection Symmetry Detection via Linear-Directional Kernel Density Estimation

Mohamed Elawady, Olivier Alata, Christophe Ducottet +2

Symmetry is an important composition feature by investigating similar sides inside an image plane. It has a crucial effect to recognize man-made or nature objects within the univer…

Joint Color-Spatial-Directional clustering and Region Merging (JCSD-RM) for unsupervised RGB-D image segmentation

Md. Abul Hasnat, Olivier Alata, Alain Trémeau

Recent advances in depth imaging sensors provide easy access to the synchronized depth with color, called RGB-D image. In this paper, we propose an unsupervised method for indoor R…

Information Criteria and Arithmetic Codings : An Illustration on Raw Images

Guilhem Coq, Olivier Alata, Marc Arnaudon +1

In this paper we give a short theoretical description of the general predictive adaptive arithmetic coding technique. The links between this technique and the works of J. Rissanen…

An improved method for model selection based on Information Criteria

Guilhem Coq, Olivier Alata, Marc Arnaudon +1

Information criteria are an appropriate and widely used tool for solving model selection problems. However, different ways to use them exist, each leading to a more or less precise…
