Open Computer Vision Library is a collection of algorithms and sample code for various computer vision problems. The library is compatible with IPL (Intel Image Processing Library) and utilizes Intel Integrated Performance Primitives for better performance.

Philosophy

Aid commercial uses of computer vision in human-computer interface, robotics, monitoring, biometrics and security by providing a free and open infrastructure where the distributed efforts of the vision community can be consolidated and performance optimized.

Computer History Graphing Project is a computer family tree.

The Computer History Graphing Project is an attempt to graph every computer standard, every piece of hardware, every OS, and every computer language in one big family tree.

Open Computer Forensics Architecture (OCFA) is a modular computer forensics framework built by the Dutch National Police Agency. The main goal is to automate the digital forensic process to speed up the investigation and give tactical investigators direct access to the seized data through an easy to use search and browse interface.
The architecture forms an environment where existing forensic tools and libraries can be easily plugged into the architecture and can thus be made part of the recursive extraction of data and metadata from digital evidence.
The Open Computer Forensics Architecture aims to be highly modular, robust, fault tolerant, recursive and scalable in order to be usable in large investigations that spawn numerous terabytes of evidence data and covers hundreds of evidence items.
Enhancements:
- This release fixes a memory leak in the evidence library and adds a workaround to limit the impact of a memory-hungry indexer module.

countertrace project is a userland, iptables QUEUE target handler for Linux 2.4 kernels running Netfilter, which attempts to give the illusion that there are multiple, imaginary IP hops between itself and the rest of the world.

The imaginary hops that countertrace projects also have the ability to introduce accumulative, imaginary latency.

How it works:

Netfilter provides a mechanism for passing packets for processing to a userland program, which can examine the packet and determine if it should be permitted through or dropped on the floor. countertrace utilizes this mechanism to drop received packets which have a TTL less than the number of hops its attempting to project, and then generates ICMP time-exceeded messages for those dropped packets with the source address of the bogus hop. If latency is also being simulated, the generated time-exceeded messages are queued for the specified period of time before being sent.

Requirements:

countertrace requires the NetPacket, Time::HiRes, and IPTables::IPv4::IPQueue perl modules, available from CPAN, the Net::RawSock and a Linux 2.4 kernel with iptables (CONFIG_IP_NF_IPTABLES) and QUEUE target (CONFIG_IP_NF_QUEUE) support. If latency is not being simulated, iptables TTL match support (CONFIG_IP_NF_MATCH_TTL) may also be useful.

Configuration:

The countertrace program takes only one command line argument, the name of its configuration file. To get started, the only configuration file command you need to know about is the "hop" command, which takes the form of "hop < address > [latency]". Hops must be added in the order in which they are to be simulated. Latency is accumulative -- at run time, the latency for each hop is determined by calculating the sum of all previously specified latency values. Additional configuration commands are available for specifying how much information is logged for each received packet; see the example-hops-configuration file for more information.

In addition to configuring countertrace itself, iptables must also be configured to pass packets to countertrace for processing using the iptables QUEUE target. If latency is not being simulated, the iptables TTL match support can be used to only pass packets to countertrace which have a TTL less than or equal to the number of hops being simulated. Otherwise, more than likely youll want all received packets to pass through countertrace, so that the latency will appear to be uniform when tracerouting, in addition to when transferring data. However, the danger is that if the countertrace program dies for any reason, iptables will drop any packets which would have been queued for userland processing, rendering the box unreachable to the outside world. To avoid the problem, it may be wise to specify at least one "backdoor" address from which packets will be accepted without passing through countertrace.
