This paper introduces a simple though effective strategy to learn a distance metric from equivalence constraints, based on a statistical inference perspective, which is orders of magnitudes faster than comparable methods.
Person Re-identification by Descriptive and Discriminative Classification
The proposed approach is demonstrated on two datasets, where it is shown that the combination of a generic descriptive statistical model and a discriminatively learned feature-based model attains considerably better results than the individual models alone.

AFLW provides a large-scale collection of images gathered from Flickr, exhibiting a large variety in face appearance as well as general imaging and environmental conditions, and is well suited to train and test algorithms for multi-view face detection, facial landmark localization and face pose estimation.
The Visual Object Tracking VOT2016 Challenge Results
The Visual Object Tracking challenge VOT2016 goes beyond its predecessors by introducing a new semi-automatic ground truth bounding box annotation methodology and extending the evaluation system with the no-reset experiment.
Real-Time Tracking via On-line Boosting
A novel on-line AdaBoost feature selection algorithm for tracking that allows to adapt the classifier while tracking the object and selects the most features for tracking resulting in stable tracking results.
A Duality Based Approach for Realtime TV-L1 Optical Flow
This work presents a novel approach to solve the TV-L1 formulation, which is based on a dual formulation of the TV energy and employs an efficient point-wise thresholding step.

This work formulate a convex optimization problem using higher order regularization for depth image up sampling, and derives a numerical algorithm based on a primal-dual formulation that is efficiently parallelized and runs at multiple frames per second.
On-line Boosting and Vision
This paper proposes a novel on-line AdaBoost feature selection method and demonstrates the multifariousness of the method on such diverse tasks as learning complex background models, visual tracking and object detection.
Semi-supervised On-Line Boosting for Robust Tracking
The main idea is to formulate the update process in a semi-supervised fashion as combined decision of a given prior and an on-line classifier, without any parameter tuning, which significantly alleviates the drifting problem in tracking applications.
