## Description

BioLeaf - Foliar Analysis™ is a professional mobile application designed for automatic and accurate assessment of leaf damage caused by insect herbivory. Using images captured directly from your phone or selected from the gallery, it identifies injured leaf regions and calculates the percentage of defoliation relative to the total leaf area.

Key features include an interactive interface with zooming and curve-based leaf edge reconstruction, four available languages (English, Portuguese, Spanish, and Russian), and suitability for multiple agricultural crops. This non-destructive tool supports plant resistance evaluation and has been developed by researchers from the Federal University of Mato Grosso do Sul and Dom Bosco Catholic University. BioLeaf is ideal for agricultural professionals, researchers, and anyone involved in crop health monitoring.
