Exemplar-based Linear Discriminant Analysis for Robust Object Tracking

Tracking-by-detection has become an attractive tracking technique, which treats tracking as a category detection problem. However, the task in tracking is to search for a specific object, rather than an object category as in detection. In this paper, we propose a novel tracking framework based on exemplar detector rather than category detector. The proposed tracker is an ensemble of exemplar-based linear discriminant analysis (ELDA) detectors. Each detector is quite specific and discriminative, because it is trained by a single object instance and massive negatives. To improve its adaptivity, we update both object and background models. Experimental results on several challenging video sequences demonstrate the effectiveness and robustness of our tracking algorithm.Comment: ICIP201

Massimiliano Balduzzi: Research in Physical Training for Performers

This essay begins the process of contextualizing and analyzing Massimiliano Balduzzi’s solo physical training practice by introducing six newly created video documents. It locates Balduzzi’s work in a wider historical and artistic context – touching upon the work of Konstantin Stanislavski, Jerzy Grotowski, and Eugenio Barba, as well as acrobatics, martial arts, and Balinese dance – while arguing that the documented physical training constitutes an original research contribution to the field of embodied technique. The essay has three main purposes: First, to give verbal articulation to some important aspects of Balduzzi’s practice, as he begins to teach more widely in New York City and beyond. Second, to test and develop a theoretical framework that conceives of embodied technique as a field of knowledge in which rigorously framed research can and does give rise to new knowledge in the form of new technique. Third, to explore the epistemological status of multimedia documentation through a focused case study. Each of these goals has the potential to expand and clarify current discussions of actor and performer training, movement analysis and documentation, and practice-as-research
