Beat-Event Detection in Action Movie Franchises
Danila Potapov, Matthijs Douze, Jerome Revaud +2
While important advances were recently made towards temporally localizing and recognizing specific human actions or activities in videos, efficient detection and classification of…
Semi-proximal Mirror-Prox for Nonsmooth Composite Minimization
Niao He, Zaid Harchaoui
We propose a new first-order optimisation algorithm to solve high-dimensional non-smooth composite minimisation problems. Typical examples of such problems have an objective that d…
DeepMatching: Hierarchical Deformable Dense Matching
Jerome Revaud, Philippe Weinzaepfel, Zaid Harchaoui +1
We introduce a novel matching algorithm, called DeepMatching, to compute dense correspondences between images. DeepMatching relies on a hierarchical, multi-layer, correlational arc…
A Universal Catalyst for First-Order Optimization
Hongzhou Lin, Julien Mairal, Zaid Harchaoui
We introduce a generic scheme for accelerating first-order optimization methods in the sense of Nesterov, which builds upon a new analysis of the accelerated proximal point algorit…
Label-Embedding for Image Classification
Zeynep Akata, Florent Perronnin, Zaid Harchaoui +1
Attributes act as intermediate representations that enable parameter sharing between classes, a must when training data is scarce. We propose to view attribute-based image classifi…
EpicFlow: Edge-Preserving Interpolation of Correspondences for Optical Flow
Jerome Revaud, Philippe Weinzaepfel, Zaid Harchaoui +1
We propose a novel approach for optical flow estimation , targeted at large displacements with significant oc-clusions. It consists of two steps: i) dense matching by edge-preservi…
