Image Progressions for the Little Target

Gillian Rosen / gtr / 16-311: Intro to Robotics

These are the image progressions for the 5" tennis ball target, the littler of the two. Images for each distance are ordered as follows: base image, thresholded, dilated/cleaned up, segmented, centroids found.
Centroids are marked as orange-and-blue crosses in each blob. Centroids are only found for the tennis balls.
