Nowadays, photos associated with spatiotemporal references are available widely on computers as well as on the Internet. There exist several tools for the exploration of photos with regard to their geographical and/or temporal structures. However, communicating spatial and temporal contents of photos remains a challenging task. In this paper, we follow Peuquet’s triad framework in visually comb...

CNNs have massively improved performance in object detection in photographs. However research into object detection in artwork remains limited. We show state-of-the-art performance on a challenging dataset, People-Art, which contains people from photos, cartoons and 41 different artwork movements. We achieve this high performance by fine-tuning a CNN for this task, thus also demonstrating that ...

Users can explore the world by viewing place related photos on Google Maps. One possible way is to take the nearby photos for viewing. However, for a given geo-location, many photos with view directions not pointing to the desired regions are returned by that world map. To address this problem, prior know the poses in terms of position and view direction of photos is a feasible solution. We can...

ecause digital cameras are so easy to use, consumers tend to take and accumulate more and more digital photos. Hence they need effective and efficient tools to organize and access photos in a semantically meaningful way without too much manual annotation effort. We define semantically meaningful as the ability to index and search photos based on the purposes and contexts of taking the photos. F...

A variety of forensic methods have been developed to identify falsified photos, each unified by the ability to estimate and detect properties of a photo that are perturbed by forgery. There exist, however, many photos in which the required properties cannot be estimated. We present an approach to detect forgery in these photos. We use this approach to detect physically inconsistent shadows and ...
