In this first part of this talk, I will present a hybrid parametric and nonparametric algorithm,exemplarcut, for generating class-specific object segmentation hypotheses. For the parametric part, we train a pylon model on a hierarchical region tree as the energy function for segmentation. For the nonparametric part, we match the input image with eachexemplarby using regions to obtain a score which augments the energy function from the pylon model. Our method thus generates a set of highly plausible segmentation hypotheses by solving a series ofexemplaraugmented graphcuts. Experimental results on the Graz and PASCAL datasets show that the proposed algorithm achieves favorable segmentation performance against the state-of-the-art methods in terms of visual quality and accuracy.
In the second part, I will present arecentbenchmark on online objecttrackingalgorithms (29 methods on 50 sequences). While much progress has been made inrecentyears with efforts on sharing code and datasets, it is of great importance to develop a library and benchmark to gauge the state of the art. After briefly reviewingrecentadvancesof online objecttracking, we carry out large scale experiments with various evaluation criteria to understand how these algorithms perform. The test image sequences are annotated with different attributes for performance evaluation and analysis. By analyzing quantitative results, we identify effective approaches for robusttrackingand provide potential future research directions in this field.
