Geometric Shape on Image via Open CV
For face detection, eyes detection or person or anything that is recorded on screen and if you want to detect it then you have to select particular ROI (Region of Interest) and for that we will draw a shape on image and that we can draw via Open CV.

Here in this publish we will understand how we can draw a geometric shape on blank image there are various kind of geometric shape we can draw with the help of Computer Vision.
Use of Geometric Shape :
- We can use Geometric Shape for detect face or draw a square on face for face detection.
- Draw user Detection
- Select Particular Area from image with help of Triangle, hexagonal, rectangle etc.
