The CAPA Apple Quality Grading Multi-Spectral Image Database

Devrim Unay; Marie-France Destain; Bernard Gosselin; Olivier Kleynen; Vincent Leemans

The CAPA Apple Quality Grading Multi-Spectral Image Database consists of multispectral (450nm, 500nm, 750nm, and 800nm) images of health and defected apples of bi-color, manual segmentations of defected regions, and expert evaluations of the apples into 4 quality categories. The defect types consist of bruise, rot, flesh damage, frost damage, russet, etc.  The database can be used for academic or research purposes with the aim of computer vision based apple quality inspection.

The CAPA Apple Quality Grading Multi-Spectral Image Database is a propriety of ULG (Gembloux Agro-Bio Tech) - Belgium, and cannot be used without the consent of the ULG (Gembloux Agro-Bio Tech), Belgium.
