CIARP 2009 - Report

After having returned from CIARP2009 in Guadalajara, MX in which I present in poster modality the paper Visual Pattern Analysis in Histopathology Images Using Bag of Features and then to return to work and academic activities (including assisting the SIB-SIPAIM 2009) I describe what I'm experience both academically and personally in my first trip abroad.

Feedback

I must thank in first place to Francisco Gomez for preparation before of poster presentation in 30 seconds, it was really useful to present the idea in such a short time. Moreover, in the poster session I present on several occasions this work (I was lucky that everyone were from hispanoamerica, so it was in Spanish jeje: P). The main remarks were about the possibility of building the visual vocabulary automatically by a method of unsupervised clustering, as control or linking semantic information and the magnification of the images, and finally on the methodology designed for automatic annotation tasks.

Works of interes

• Texture analysis methods and applications. Prof. Maria Petrou University of Cambridge, UK. This was an interesting tutorial about texture analysis and description methods, also she shows your book about this. This is very important for the relationship with histology images for tissue description.
• We are Building a Topological Pyramid. Prof. Walter G. Kropatsch. Vienna University of Technology, Viena. This was other interesting tutorial about graph representation of objects in image processing for segmentation and others using topological and connectivity information in order to reduce this representation.
• Randomized Probabilistic Latent Semantic Analysis for Scene Recognition. Erik Rodner and Joachim Denzler. This was an interesting work that use bag of feature and pLSA for image categorization in natural scene images.
• Classifier Selection in a Family of Polyhedron Classifiers. Tetsuji Takahashi, Mineichi Kudo and Atsuyoshi Nakamura. An interesting paper where the authors proposed a classifiers for SVM where choose the decision space with polyhedrons that reduce the convex hull with relative better results.
• Clustering Ensemble Method for Heterogeneous Partitions. Sandro Vega-Pons and José Ruiz-Shulcloper. This work is about clustering method addressed to ensemble for heterogeneous partitions. The application in hierarchical clustering can be explored.
• Improved Online Support Vector Machines Spam Filtering Using String Kernels. Ola Amayri and Nizar Bouguila. Good paper about machine learning using string kernels and Transductive Support Vector Machines. The more interesting of this work is the exhaustive experimentation and configuration setup.
• A New Incremental Algorithm for Overlapped Clustering. Airel Pérez Suárez, José Fco. Martínez Trinidad, Jesús A. Carrasco Ochoa, and José E. Medina Pagola. This is a good work about incremental clustering, very useful when we have large datasets and when a new data arrive, we don't want the clustering again. Closely related with our work and maybe a collaborative work is possible.

Contacts

Ioannis A. Kakadiaris, Ph.D. He is Director of Computational Biomedicine Laboratory and Division of Bioimaging and Biocomputation Institute for Digital Informatics and Analysis at University of Houston, Houston, Texas, USA. He was the only keynote speaker who works in biomedical imaging. We spoke about cardiac image problems in 4D (spatial and time resolution trade-off) and the possibility of collaborative work and an invitation to Bioingenium Reseach Group for similiar research topics, to which he showed interest and possibilities under its schedule.

Lic. Airel Perez Suarez. He is a reseacher in computer science of Centro de Aplicaciones de Tecnologías Avanzadas (CENATAV). He works in data minning and information retrieval. He shows a paper about incremental algorithm for overlapped clustering and he is interested in test your algorithm with our histology images dataset and visual words for collaborative works.

Dr. José Ruiz Shulcloper. He is Director of Centro de Aplicaciones de Tecnologías Avanzadas (CENATAV) and president of the Cuban Association for Pattern Recognition. He invite us to start the fundation of Colombian Association for Pattern Recognition in order to enter at International Association of Pattern Recognition (IAPR). For this, he said that we can to start from an actual association related with pattern recognition (for example, Sociedad Colombiana de Computación), only we must send the information request for this purpose to your mail.

Erik Rodner. He is rearcher in chair of computer vision from Institute of Computer Science at University of Jena. He shows two works, one about image categorization using Bag of Features in natural scene images and object recognition using a visual feature combination with bag of features from 2D and 3D images.

Note: For future conferences is very important to carry presentation cards.
