Simple bounding box operations

Project description

Package bbx

Simple operations over bounding boxes. The package provides a class Boxes encapsulating a set of bounding boxes. Internally, the boxes are represented in an Nx4 matrix with x1,y1,x2,y2 coordinates. Instances of Boxes support arbitraty user-defined fields which can hold other properties of boxes like e.g. score.

import bbx

B = bbx.Boxes([0,0,10,10])  # New instance
B.set_field("score", [1])  # Set the field
B.width()  # [10]
C = bbx.resize(B, 2)  # Resize and make new instance
C.get() # [[-5,-5,15,15]]
C.get_field("score")  # [1]
C.area()  # [400]

But why?

... for the glory of s... But seriously, I use bounding boxes in every other project and there is no decent small package for this. Yes I can use TF obj detection api (and I did for a while, this pkg have similar interface to it) or structures from imgaug or others. I did not find anything that suits my needs (if you know about something just let me know). You either install a big non-standard package with tons of functionality you do not need or you implement it by yourself. So I decided to make a very small package that does precisely what I need and nothing more, is portable (just numpy needed, and you already have it!).

Yes, I just implemented a non-standard package, so I so not need to use other non-standard packages... yes, I know...


The package is in PyPI so just use pip

pip install bbx
