1. Consider a circle and an ellipse that might be viewed by a vision system. The circle has a 4” radius, whereas the ellipse has a minor and major radius of 2” and 4”. Compare the two definitions using form factors (compactness and thickness) and show how they differ.
ans. Resolution of a video image describes the number of rows and columns of pixels in a video image. A higher resolution means that there are more rows of pixels in the images, and therefore we can distinguish smaller details.
4. We have four part shapes (as listed below) that will be arriving on a conveyor. We want to develop a decision tree for the vision system to tell them apart. We also need to find their centroids relative to the top left of the image so that a robot may pick them up.
