- Bounding box of ImageNet images
Annotation file format: Img_W Img_H xmin xmax ymin ymax
- Problems of Current Approach
- some images are too large
- the "null" string in result should be replaced by -1 -1 -1 -1
- the following plot is that, if each image has a certain number of annotations (x axis),
how many images can be inferred a true bounding box.
By the plot, we suggest using 6 annotations for each image to label.
