Detecting Silver Balls on a white background

OpenMV Boards
1

Hi, can you please tell how to find silver balls on a white background without any AI model? We tried using blob detection but because the values are very similar it often tend to take the white backround as silver. We would appreciate an early response.

You need to add some feature tracking. See the circle detection method.

Otherwise, this is very hard as color tracking is all about contrast.

Thanks for an early response. We are new to OpenMV so can you please specify what you mean by feature tracking?

We have examples for feature tracking in the IDE. Features are like geometrical things. So, find_circles() will look for circular objects.
