Pomegranate Thermal Images
Description
This dataset includes thermal images of pomegranate. The dataset consists of thermal images of pomegranate taken post harvesting. The pomegranates are at first stored and ensured that they are brought to temperature below the ambience. The temperature difference is necessary to allow the thermal radiation between pomegranate and the atmosphere. The digital image and thermal image of the same fruit is taken by placing both cameras at same angle. The fruits with digital and thermal images are categorized in three parts viz. no defect, minor defect and major defect. This categorization is done manually.

Steps to reproduce
1. Refrigerate pomegranate for 60 minutes 2. Take out refrigerated pomegranates and keep it at room temperature for 10 minutes 3. Place the pomegranate on the table and click digital image, thermal image with full spectrum and black & white thermal image. 4. The fruit with internal defects shows dark spots on surface whose temperature is different as compared to healthy part of the fruit. 5. The internal defects are validated by cutting the fruit and visually inspecting internal structure.
