Pandemic Objects: Photographs

Real-world objects are more memorable than photographs of objects

Research studies in psychology typically use two-dimensional (2D) images of objects as proxies for real-world three-dimensional (3D) stimuli. There are, however, a number of important differences between real objects and images that could influence cognition and behavior. Although human memory has been studied extensively, only a handful of studies have used real objects in the context of memor...

Dynamic Insertion of Virtual Objects in Photographs

Introducing virtual objects in photographs or video sequences presents several challenges, such as the pose estimation and the visually correct interaction boundaries of such objects. In this article a framework for the introduction of virtual objects in user-captured photos is discussed. Furthermore, the introduced virtual objects should be interactive and respond to real physical environments...

ReferItGame: Referring to Objects in Photographs of Natural Scenes

In this paper we introduce a new game to crowd-source natural language referring expressions. By designing a two player game, we can both collect and verify referring expressions directly within the game. To date, the game has produced a dataset containing 130,525 expressions, referring to 96,654 distinct objects, in 19,894 photographs of natural scenes. This dataset is larger and more varied t...

Reality: An Interactive Reconstructiuon Tool of 3D Objects from Photographs

Modeling of complex 3D objects is a painful and timeconsuming task. The work presented here focuses on the reconstruction of a 3D model of existing objects starting from photographs, using a paradigm called ImageBased Modeling. Automatic approaches for Image-Based Modeling, as developped in Computer Vision for instance, have shown their limits, as some ambiguities can only be solved by a human ...
