[article]
2020
arXiv
pre-print

Associating the unique ID with metadata for memory objects, obtaining and managing the pointer graph metadata can be efficiently. ...
Coupled with the Address Tagging architecture on an ARM64 system, our experiments show that the DangKiller can eliminate use-after-free vulnerabilities at only 11% and 3% runtime overheads for the SPEC ...
The pointer tracking module tracks the locations of dangling pointer candidates;and the delayed free module frees the object when it has no references. ...

Model-free tracking aims identify the location of particular objects or object parts in each frame of a video based on a single positive example. ...
Together with other recent advances in object detection and tracking, we believe these developments will ultimately contribute to solving the long-term tracking problem. ...
We propose a new tracking algorithm, called structure-preserving object tracking (SPOT), that uses a part-based appearance model based on pictorial structures. ...

We demonstrate the effectiveness of the approach in a state-of-the-art object detector based on deformable template models, the parameters of which are adapted online using an online structured SVM. ...
A major limitation of such an approach is that a single, generic detector is used to track specific objects; the additional information on the visual appearance of the particular object under consideration ...
Many prior studies in model-free tracking focus on exploring different feature representations for the target object, including feature representations based on points [27] , [28] , [29] , contours ...

In our approach, we generate state-chart graphs by tracking data on the atomic instructions invoked on the concurrent object during model checking and represent the atomic instructions as states in a state-transition ...
A set of operations are commutative if changing the order of their execution on an object does not affect the abstract state of the object and returns the same response. ...
Commuter and our tool are both based on conditional states, but Commuter does not track object-level model checking data. ...
