Software that automatically fixes itself, without shutting down

Invariant DetectionThis is supposing that the software is simple enough to determine invariants and not block valid code paths that are infrequently used. It sounds a lot like applying design by contract after the fact.Software That Fixes Itself?The headline implies an application that fixes itself. The article describes and...

Detecting Image Spam Using Local Invariant Features and Pyramid Match Kernel

Image spam is a new obfuscating method which spammers invented to more effectively bypass conventional text based spam filters. This paper extracts local invariant features of images and runs a one-class SVM classifier which uses the pyramid match kernel as the kernel function to detect image spam. Experimental results demonstrate...

A Novel Feature Descriptor Invariant to Complex Brightness Changes

This paper describes a novel and robust feature descriptor called Ordinal Spatial Intensity Distribution OSID which is invariant to any monotonically increasing brightness changes. Many traditional features are invariant to intensity shift or affine brightness changes but cannot handle more complex nonlinear brightness changes, which often occur due to the...

Face Recognition Based on Statistical Moments 1 (Windows)

Face Recognition Based on Statistical Moments - Matlab source code. Moment based feature descriptors have evolved into a powerful tool for image analysis applications. Geometric moments present a low computational cost, but are highly sensitive to noise. We have developed a simple and efficient technique for face recognition that combines:...

StdMap 4.5 (Mac)

Area-preserving mappings model the dynamics of such systems as forced pendulums and the dynamics of stars in galacties and the flow of magnetic field lines. StdMap displays the orbits of 13 different such mappings which exhibit chaotic and regular dynamics. With the program you can find periodic orbits, stable manifolds...

Filtering Spam With Behavioral Blacklisting

Spam filters often use the reputation of an IP address or IP address range to classify email senders. This approach worked well when most spam originated from senders with fixed IP addresses, but spam today is also sent from IP addresses for which blacklist maintainers have outdated or inaccurate information...

Identifying fingerprints in seconds

Researchers at the University of Warwick, UK, say they have developed a technology to identify damaged fingerprints in just a few seconds. Their approach neglects surface marks and focuses on underlying patterns. The researchers claim that their technique is fast and 100% accurate -- at least it was on 500...

Self-Similar Properties Under the Bandwidth Restrainment

The scale-invariant burstiness or self-similarity has been found in real networks. Relation between self-similarity and networks and/or system parameter is the center of discussion in the context of application layer. This self-similarity is caused by the file size of Web servers or the duration of user sessions. In addition, self-similar...

Adaptive Correctness Monitoring for Wireless Sensor Networks Using Hierarchical Distributed Run-Time Invariant Checking

This paper presents a hierarchical approach for detecting faults in Wireless Sensor Networks WSNs after they have been deployed. The developers of WSNs can specify "Invariants" that must be satisfied by the WSNs. It presents a framework, Hierarchical SEnsor Network Debugging (H- SEND), for lightweight checking of invariants. H-SEND is...

Image Registration 1 (Windows)

Image Registration - Matlab source code. In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different coordinate systems. Image registration is the process of transforming the different sets of data into one coordinate system. ...
