Pattern Matching and Automatic Photo-Identification of Individual Amphibians

AmphIdent


Automatic photo-identification and pattern matching software for Amphibians

The software AmphIdent allows to automate the photo-identifi­ca­tion process of distinct amphi­bian indivi­duals in capture-recapture studies. Hereby, specific patterns on digital photographs are analyzed and a pattern recognition and pattern matching process reveals recaptured individuals. Captured patterns are automatically managed in a database. AmphIdent offers a decent recognition rate and a simple operation. Currently, the following species are supported:
