Real-Time Occlusion Handling in Augmented Reality Based on an Object Tracking Approach
To produce a realistic augmentation in Augmented Reality, the correct relative positions of real objects and virtual objects are very important. In this paper, we propose a novel real-time occlusion handling method based on an object tracking approach. Our method is divided into three steps: selection of the occluding object, object tracking and occlusion handling. The user selects the occludin...
متن کاملHandling occlusion in augmented reality systems: a semi-automatic method
We present a semi-automatic approach to solve occlusion in AR systems. Once the occluding objects have been segmented by hand in selected views called key-frames, the occluding boundary is computed automatically in the intermediate views. To do that, the 3D reconstruction of the occluding boundary is achieved from the outlined silhouettes. This allows us to recover a good prediction of the 2D o...
متن کاملMean Shift Object Tracking with Occlusion Handling
An object tracking algorithm using the Mean Shift framework is presented which is largely invariant to both partial and full occlusions, complex backgrounds and change in scale. Multiple features are used to gain a descriptive representation of the target object. Image moments are used to determine the scale of the target object. A kalman filter is used to successfully track the target object t...
متن کاملReal-Time Multi-object Tracking with Occlusion and Stationary Objects Handling for Conveying Systems
Multiple object tracking has a broad range of applications ranging from video surveillance to robotics. In this work, we extend the application field to automated conveying systems. Inspired by tracking methods applied to video surveillance, we follow an on-line trackingby-detection approach based on background subtraction. The logistics applications turn out to be a challenging scenario for ex...
متن کاملReal Time Tracking Using Stereo Vision for Augmented Reality
Correct tracking of the user position is crucial for an Augmented Reality (AR) application. For this reason, tracking became a very important research subject in the field of real-time AR. The most common solution to implement an AR system is based on the use of an Head Mounted Display (HMD) and two cameras for the stereoscopic video see-through visualization. Almost all the systems presented i...
