# 🍓 The RaspGrade Dataset: Towards Automatic Raspberry Ripeness Grading with Deep Learning
This research investigates the application of computer vision for rapid, accurate, and non-invasive food quality assessment, focusing on the novel challenge of real-time raspberry grading into five distinct classes within an industrial environment as the fruits move along a conveyor belt. 
To address this, a dedicated dataset of raspberries, namely RaspGrade, was acquired and meticulously annotated. 

Instance segmentation experiments revealed that accurate fruit-level masks can be obtained; however, the classification of certain raspberry grades presents challenges due to color similarities and occlusion, while others are more readily distinguishable based on color
