Goal: detect the location of an object within an image. Fully supervised:. Training data labeled with object category and ground truth bounding boxes. Weakly supervised:. Only object category is known, no location info. Recognition(. 细粒度分类. ) . 沈志强. Datasets. . -- Caltech-UCSD Bird-200-2011. Number of categories: 200. Number of images: 11,788.
