If `im` is 2D and the length of second dimension are 4 or 5, it will be viewed as bounding box data (x0, y0, w, h,

Users can also directly plot text
```python

Args:
axis: The matplotlib axis to plot on, or None for a new plot.
fig: A reference to the figure to plot on, or None if new plot.
im: The image (width X height) / bounding box / text to display.
title: A title for the image.
color_map: Which colormap to use for greyscale images.
stack_depth: Multiple images can be drawn onto the same axis. When stack depth is greater than zero, the `im`
will be alpha blended on top of a given axis.
Returns:
plotted figure. It will be the same object as user have provided in the argument.
