We had learned from the non-ML-based ball detection algorithm that a color-and-contour-based algorithm cannot always detect the ball with enough accuracy. As a result, I have been developing an ML-based platform for training a model with multiple images of the ball and identifying a bounding box aro...

The ball detection algorithm (without the use of a trained model) has been completed. Following the work posted in the last blogpost, I realized that it may be a better idea to isolate the ball away from its environment and determine its bounding box in the cropped image. The first analysis of the b...

Over the last two weeks, I have been working on the existing code by Parth Agrawal for the estimation of the location of the green ball from images that were shot at different angles. The code had estimated the position of the ball quite well for the hi-def images but not so for the 800x600 images:...

Recently, I've been looking into methods to potentially improve the depth map produced by an Intel RealSense D435i, and OpenCV's disparity filter ([1], [2], [3]) seemed like a good initial starting point. At a high level, after generating a disparity map between left and right camera images vi...
