Workflow Monitoring based on Multi-view Reconstruction

Daniel Weinland

Activity recognition has primarily addressed the identification of either actions or well-defined interactions among objects in a scene. In this work, we extend the scope to the study of workflow monitoring. In a workflow, ordered groups of activities (pha ...

Who's Doing What: Joint Modeling of Names and Verbs for Simultaneous Face and Pose Annotation

Barbara Caputo, Jie Luo, Vittorio Ferrari

Given a corpus of news items consisting of images accompanied by text captions, we want to find out “who’s doing what”, i.e. associate names and action verbs in the captions to the face and body pose of the persons in the images. We present a joint model f ...

A collaborative approach to image segmentation and behavior recognition from image sequences

Laura Ioana Gui

Visual behavior recognition is currently a highly active research area. This is due both to the scientific challenge posed by the complexity of the task, and to the growing interest in its applications, such as automated visual surveillance, human-computer ...

Towards Robust Place Recognition for Robot Localization

Barbara Caputo, Jie Luo

Localization and context interpretation are two key competences for mobile robot systems. Visual place recognition, as opposed to purely geometrical models, holds promise of higher flexibility and association of semantics to the model. Ideally, a place rec ...

Calibration from statistical properties of the visual world

What does a blind entity need in order to determine the geometry of the set of photocells that it carries through a changing lightfield? In this paper, we show that very crude knowledge of some statistical properties of the environment is sufficient for th ...

A Web Survey for Facial Expressions Evaluation

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini

In the recent years, researchers have investigated several methods of facial expression analysis. Their interest has been to apply their algorithms to sets of images labelled by a restrained number of experts. In order to deal with the generalizability of ...

Préhenseurs, conditions et stratégies pour une micromanipulation de précision

Mélanie Dafflon

Currently microsystems consist of more and more functionalities in even smaller volumes. Components size has then to be reduced as well, coming through micro- and then nanoscale. The industrial equipments dedicated to their fabrication and assembly have co ...

Keypoint Signatures for Fast Learning and Recognition

Pascal Fua, Vincent Lepetit, Michael Calonder

Statistical learning techniques have been used to dramatically speed-up keypoint matching by training a classifier to recognize a specific set of keypoints. However, the training itself is usually relatively slow and performed offline. Although methods hav ...

Face Detection Using Discrete Gabor Jets and a Probabilistic Model of Colored Image Patches

Touradj Ebrahimi, Ashkan Yazdani, Ulrich Hoffmann

Face detection allows to recognize and detect human faces and provides information about their location in a given image. Many applications such as biometrics, face recognition, and video surveillance employ face detection as one of their main modules. The ...
