Upgrading

Upgrading to Face Matcher 3.0

In order to utilize the great accuracy benefits from Face Matcher 3.0, any templates and enrolled caches must be discarded and rebuilt. Any existing caches will need to be deleted or moved while Face Matcher is not running, so that it can create new ones with the updated configuration.

Upgrading without rebuilding cache

If you have an existing cache and are unable to re-generate your templates and cache, you can still upgrade the software without losing your cache.

First, note that Face Matcher will never delete your cache. If you have an invalid configuration, it will simply fail to start.

What determines the compatibility of templates from 2.X versions using F500 and 3.0 is the “F500_general.bin” file. The “F500_general.bin” that is shipped with 3.0 is not compatibile with 2.X templates. Thus, if you use the “F500_general.bin” that your existing 2.X Knomi Face Matcher, it will still continue to load and generate 2.X templates. This will allow you to keep your existing templates and caches, however you will not be able to benefit from the increased accuracy of the 3.0 release.
