The LTI-Lib Computer Vision Library

LTI-Lib is a cross-platform (Linux and Windows) computer vision and image processing library that was written in C++.

The library is divided into the following sections:

• Encapsulation of Windows/Linux functionality.
• Linear algebra.
• Classification and Clustering.
• Image Processing.
• Visualization and Drawing Tools.

The Conceptual Class Hierarchy document gives a much more detailed explanation of the library contents.

One interesting feature of LTI-Lib is a Perl language scripting system that can be used to generate template files, making use of the library straightforward. For details, see the LTI-Lib Architecture document, which is part of the Online Manual.

LTI-Lib Version Beta 1.9.3 was announced this week.

"This release provides new functors and features, many bug fixes and more documentation."

Dependencies include GCC 2.95.3 or newer, Perl, and the GTK libraries. LTI-Lib has been released under the GNU Lesser General Public License (LGPL). The code is available for download here.

Speex 1.0.1 Released

Version 1.0.1 of the Speex speech codec is available. "This release fixes several minor bugs that were found in version 1.0 as well as a major bug in the wideband encoding. This makes files encoded with 1.0 play with lower quality on 1.0.1 decoders. Upgrading to 1.0.1 is highly recommended, especially for wideband users. As such, reencode wideband files using a 1.0.1 encoder if you can."

It is a testament to the robustness of Firebird 1.0 that no major problems have been found that have required fixing. However, almost six months have passed since the Fb 1.0.2 and several bug fixes and enhancements have appeared. Rather than letting them molder indefinitely it is better to get them out into the big wide world."

Mozilla Firebird Raises the Browser Bar (DevX)

DevX reviews Mozilla's Firebird. "Although there are numerous popup-blocking add-ons for Internet Explorer, Mozilla has taken it one step further: popup-blocking capability is built into the browser. It's not an afterthought. If you have some sort of strange popup ad fetish or you visit sites that use popups for necessary functionality, you can turn the feature off (even for individual sites), but personally, I'm only sorry that the popup blocker doesn't also make the person responsible for the popup ad turn into a toad or something equally unpleasant. Popup blocking may not be a sufficiently persuasive reason to switch browsers, but tabbed browsing is a major advance."
