'Hass' Avocado Ripening Photographic Dataset

This dataset consists of 14,710 labeled photographs of Hass avocados (Persea Americana Mill. cv Hass), resized to 800 x 800 pixels and saved in the .jpg format, designed to facilitate the development of deep learning models for predicting ripening stages and estimating shelf-life.

A total of 478 Hass avocados were acquired three days post-harvest and categorized into three storage groups: T10 at 10 ºC with 85% relative humidity (RH); T20 at 20 ºC with 85% RH; and Tamb under ambient conditions.

The ripening process of these avocados was documented through daily photographs (2 of each sample of opposite sides), each linked to a detailed Ripening Index with five stages:
1 - Underripe;
2 - Breaking;
3 - Ripe (First Stage);
4 - Ripe (Second Stage);
5 - Overripe.

The fourth stage marked the end of the avocados' shelf-life, with any sample classified as stage 5 considered beyond its prime. Time stamps on each photograph enable the tracking of the duration from any photograph, to the point each avocado reached the end of its shelf-life.

Additionally, an Excel spreadsheet accompanies the dataset, listing all photograph filenames, their corresponding sample number, storage group, classification according to the 5-stage Ripening Index, the day the photograph was taken relative to the start of the experiment, and the side of the fruit photographed (a or b).
