Petroglyphs (rock engravings) have been pecked and engraved by humans into natural rock surfaces thousands of years ago and are among the oldest artifacts that document early human life and culture. Some of these rock engravings have survived until the present and serve today as a unique document of ancient ...

Publisher: IEEE Computer Society
Bibliometrics:
Citation Count: 0

In this paper, we present a novel object detection approach that is capable of regressing the aspect ratio of objects. This results in accurately predicted bounding boxes having high overlap with the ground truth. In contrast to most recent works, we employ a Random Forest for learning a template-based model ...

Robust multi-object tracking-by-detection requires the correct assignment of noisy detection results to object trajectories. We address this problem by proposing an online approach based on the observation that object detectors primarily fail if objects are significantly occluded. In contrast to most existing work, we only rely on geometric information to ...

Citation Count: 17

Online learning has shown to be successful in tracking-by-detection of previously unknown objects. However, most approaches are limited to a bounding-box representation with fixed aspect ratio and cannot handle highly non-rigid and articulated objects. Moreover, they provide only a limited foreground/background separation, which in turn, increases the amount of noise ...

Highlights� We introduce a novel method to fuse arbitrary single target tracking approaches. � We show how to transform diverse tracking outputs to a common representation. � Object segmentations are iteratively computed from the fused tracking outputs. � Performance based weighting of the trackers further increases the accuracy. � We ...

In this paper we present an approach for visualizing time-oriented data of dynamic scenes in an on-site AR view. Visualizations of time-oriented data have special challenges compared to the visualization of arbitrary virtual objects. Usually, the 4D data occludes a large part of the real scene. Additionally, the data sets ...

In this paper, we introduce a formulation for the task of detecting objects based on the information gathered from a standard Implicit Shape Model (ISM). We describe a probabilistic approach in a general random field setting, which enables to effectively detect object instances and additionally identifies all local patches contributing ...

We present a variational segmentation method which exploits color, edge and spatial information between an arbitrary number of views. In contrast to purely image based information like color and gradient, spatial consistency is a new cue for segmentation, which originates from the field of 3D reconstruction. We show that this ...

In this paper we propose a novel, game-theoretic approach for finding multiple instances of an object category as sets of mutually coherent votes in a generalized Hough space. Existing Hough-voting based detection systems have to inherently apply parameter-sensitive non-maxima suppression (NMS) or mode detection techniques for finding object center hypotheses. ...

We propose a novel formulation to express the attachment of a polygonal surface to a skeleton using purely linear terms. This enables to simultaneously adapt the pose and shape of an articulated model in an efficient way. Our work is motivated by the difficulty to constrain a mesh when adapting ...

Fully automatic localization of anatomical structures in 2D and 3D radiological data sets is important in both computer aided diagnosis, and the rapid automatic processing of large amounts of data. We present a simple, accurate and fast approach with low computational complexity to find anatomical landmarks, based on a multi-scale ...

Highlights� Classifier grids showed excellent detection results for stationary cameras. � On-line adaptive classifiers reduce the complexity of the classification task. � Fixed update strategies allow long-term stability. � Short-term stability through proposed inverse multiple instance learning.

The goal of our work is to incrementally reconstruct terrestrial city models from standard digital camera images contributed by multiple users. Hence, the Wiki principle well known from textual knowledge databases is transferred to 3D computer vision. Many state-of-the-art computer vision methods must be applied and modified according to the ...

In this paper we introduce a novel real-time method to track weakly textured planar objects and to simultaneously estimate their 3D pose. The basic idea is to adapt the classic tracking-by-detection approach, which seeks for the object to be tracked independently in each frame, for tracking non-textured objects. In order ...
