• W4241328047 abstract "Event Abstract Back to Event Classification of Cells Based on Scale-space Measures and Semi-supervised Machine Learning Sumit K. Vohra1*, Laura Antanas1, Luc De Raedt1 and Dimiter Prodanov2* 1 KU Leuven, Department of Computer Science, Belgium 2 IMEC, Belgium Morphometric analysis and identification of different phenotypes of brain cells has become increasingly important. Accurate identification of individual cellular phenotypes can be obtained by combining automated microscopic acquisition with extensive morphological feature extraction and data mining strategies. In order to classify brain cells in a robust manner involving little human attention, there is a need for effective computational methods for quantification of the neuronal dendritic trees and glial cells. Thus, we propose a semi-supervised active learning-based and geometrical measures for confronting with image's jaggedness. In contrast to threshold based learning approaches, where the learning model is sensitive to global or a local threshold parameters, we evaluated the geometrical features using Laplacian of Gaussian operator (Duits 2003) and scale representation generated by Anisotropic decomposition of the Laplacian (Anisotropic filter, ALoG Filter (Weickert 1998) & (Lindberg 1994)). The learning is performed using active learning framework and Weka. We are implementing a generic tool in ImageJ Plugins for combining all the above computational methods. The technique is successfully applied to two-photon images where intensity threshold-based approaches did not perform adequately (Mols 2013). References Duits R, M. Felsberg, L. Florack, and B.
