For the image datasets, there may be a bounding box for each image at the dataset. It is an annotation for an image. It is a rectangular box intended for focusing on something inside the image.
I read about the following two types of representations for a bounding box.
- using two points $(x_1, y_1)$ and $(x_2, y_2)$.
- Using a point $(x_1, y_1)$, width, and height. $$<x_1><y_1><width><height>$$
How do understand both the representations, Specifically, does the point $(x_1, y_1)$ used to denote the top right or top left or bottom right or bottom left in both cases?
