- you are assuming two objects, yet, this line: if (size(BBox,1)> 2) requires more than two objects; I think that you meant to write: if (size(BBox,1) >= 2)
- I assume that you have hshapeins configured to draw lines; if that's correct then your code should work
Display changing lines using Computer Vision Toolbox. PLEASE HELP!

I am writing a program using the Computer Vision Toolbox. My program detects two objects by thresholding and then using Blob analysis to place bounding boxes around the objects. I would like to insert a line between the bounding boxes and eventually find the distances between the objects. However, the bounding boxes are only present when the objects are in the video and therefore the lines will not always be present. I have tried this:
if (size(BBox,1)> 2)
pts = [BBox(1,1) BBox(1,2) BBox(2,1) BBox(2,2)];
Imr = step(hshapeins, Imr, pts);
If anyone has any idea how to do this please comment!!! Thanks.

This would connect upper left corners of the bounding boxes. What you are doing makes sense. What is the exact problem that you are running into?
I see some issues in the code above:
