The Data Base
The GroZi-120 is a multimedia database of 120 grocery products. The objects belonging to it vary in color, size, opacity, shape and rigidity.
Every product has two different representations in the database: one captured in vitro and another in situ. The in vitro images are isolated and captured under ideal imaging conditions (e.g. stock photography studio or a lab).
On the other hand, in situ representations come from natural environments (real world). We shot 29 videos on the same day. Such videos include every product present in the in vitro part of the dataset. These images were selected every 5 frames and were stored together with their location in the video. These images present variations in scale, illumination, reflectance, color, pose and rotation, while the video frames provide a cluttered background.
