Bounding box Label
- Annotation file format:
Img_W Img_H xmin xmax ymin ymax
- Problems of Current Approach
- some images are too large to be displayed within the screen, so have bad annotation.
- 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.
View Point Label
- Ask labelers to do a selection question with each branch to be a frame sampled from video sequences. We plan to sample those frames from equally distributed angles.
