Dataset論文：RP2K: A Large-Scale Retail Product Dataset for Fine-Grained Image Classification
(1) It is by far the largest scale dataset in terms of product categories.
(2) All images are captured manually in physical retail stores with natural lightings, matching the scenario of real applications.
(3) We provide rich annotations to each object, including the sizes, shapes and flavors/scents. We believe our dataset could benefit both computer vision research and retail industry.
