TEMA AIIA_wildfire Dataset

General description of the dataset

The TEMA AIIA_wildfire dataset is a collection of 2,236 natural disaster images designed for semantic segmentation, focusing on burnt areas, smoke, and fire. It aggregates and standardizes images from three distinct sources: the BLAZE classification dataset (https://aiia.csd.auth.gr/blaze-fire-classification-segmentation-dataset/), Finland’s wildfire dataset  and Sardegna’s wildfire dataset. If one uses any part of these datasets in his/her work, he/she is kindly asked to cite the following paper:

Dataset Structure

The dataset is organized by source, each with standard train/validation splits containing .jpg images and corresponding .png label masks. The corresponding folder for each source are BLAZE (BLAZE1), Finland’s (KAHY) and Sardegna’s (RAS). Labels follow a four-class hierarchy (0: background, 1: burnt, 2: smoke, 3: fire). The final composition is 984 images from BLAZE ( 584 from KAHY, and 668 from RAS, split into 1,527 training and 655 validation images almost a 70 – 30% split.
