The problem with this is that it brings to the table all the minuses of the c language.

Opencv python is a library of python bindings designed to solve computer vision problems cv2 puttext method is used to draw a text string on any image.
The class mat represents an n dimensional dense numerical single channel or multi channel array.
The functions ellipse with less parameters draw an ellipse outline a filled ellipse an elliptic arc or a filled ellipse sector.
Welcome the podcast from the opencv team.
Opencv support about 3 types subtraction algorithm.
In those days the library was built around a c interface and to store the image in the memory they used a c structure called iplimage.
If you need more control of the ellipse rendering you can retrieve the curve using ellipse2poly and then render it with polylines or fill it with fillpoly.
It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat.
Background subtraction bs is a common and widely used technique for generating a foreground mask namely a binary image containing the pixels belonging to moving objects in the scene by using static cameras.
