Topic： Distance Metric Learning in Person Re-identification Abstract: Matching people across non-overlapping camera views at different locations and different time, known as person re-identification, is both a hard and important problem for associating behavior of people observed in a large distributed space over a prolonged period of time. Person re-identification is fundamentally challenging because of the large visual appearance changes caused by variations in view angle, gesture, lighting, background clutter, and occlusion. Due to these challenges, it is hard to extract distinctive and reliable visual features across camera views. Hence, seeking an optimal and robust similarity measure that quantifies a wide range of features against realistic viewing conditions is critically important for person re-identification. This talk will present our recent research works on distance metric learning for robust cross-view matching, including relative distance comparison model and its transfer extension for solving the open-world matching problem, an asymmetric view-transform distance model, a cross-scale subspace model, a cross-scenario transfer model, and a top-push distance metric learning for video re-id.
