Hi,
I am working on an Image Processing project where wesort the objects depending on their shapes on a conveyor.
The acquisition and the process is done however right now i put the object right in front of the camera and then acquire and process the image and i get the shape of the object.
Now what I want to do is to start moving the conveyor and MATLAB to understand when the object has arrived and when the object arrives to process the image
How can I detectthe new coming object to the image ?
p.s:
the conveyor is black. when there arent any objects on the conveyor what the camera gets is a black plain surface
Thanks

There are several ways:

- Use an independent detection system, e.g. a laser, weight or
something like that, and detect when an object is in the correct
position to be imaged.

- Take several images and estimate the position, size and
characteristics
of any objects present. Make the reject / accept decision only on
the
information from images where the object is at the centre of the
image.
