IBM Corp is going to distribute Excalibur Technologies Inc’s PixTex/EFS document imaging and information retrieval software on the RS/6000 through its direct sales force. Meanwhile, San Diego-based Excalibur last week announced its XRS multimedia information retrieval software tool kit, claiming it’s the first software designed to manage storage and retrieval of multimedia data such as text, image, video and signal data in its native digital form. With XRS technology, it will no longer be necessary manually to label every frame of a movie with a description of its contents. Based on the company’s Adaptive Pattern Recognition Processing, XRS uses an advanced technology to analyse patterns in digital data. The tool kit is a series of callable object libraries written in C that programmers can use to build multimedia indexing and retrieval capabilities directly into their applications. XRS was used to build PixTex/EFS.
