Object Tracking Using Motion Direction Detection
We present an algorithm for tracking objects in a video sequence, based on a novel approach for motion detection. We do not estimate the velocity eld. Instead we detect only the direction of motion at edge points and thus isolate sets of points which are moving coherently. We use a Hausdor distance based matching algorithm to match point sets in local neighborhood and thus track objects in a vi...
متن کاملSelf-motion impairs multiple-object tracking.
Investigations of multiple-object tracking aim to further our understanding of how people perform common activities such as driving in traffic. However, tracking tasks in the laboratory have overlooked a crucial component of much real-world object tracking: self-motion. We investigated the hypothesis that keeping track of one's own movement impairs the ability to keep track of other moving obje...
متن کاملMultiple Object Tracking Using Local Motion Patterns
This paper presents an algorithm for multiple-object tracking without using object detection. We concentrate on creating long-term trajectories for unknown moving objects by using a model-free tracking algorithm. Each individual object is tracked by modeling the temporal relationship between sequentially occurring local motion patterns. The algorithm is based on shape and motion descriptors of ...
متن کاملConflicting motion information impairs multiple object tracking.
People can keep track of target objects as they move among identical distractors using only spatiotemporal information. We investigated whether or not participants use motion information during the moment-to-moment tracking of objects by adding motion to the texture of moving objects. The texture either remained static or moved relative to the object's direction of motion, either in the same di...
متن کاملDo distractors disrupt prediction in multiple object tracking?
Additional distractors are known to disrupt multiple object tracking (MOT) performance. Our previous work with motion-defined stimuli argues that increased errors cannot be entirely due to confusions between targets and distractors. Since distractors are known to disrupt motion extrapolation in a variety of tasks, from smooth pursuit to time-to-contact judgments, we suggest that distractors deg...
