This week, I worked mainly on edge detection and color extraction. Both approaches were changed from initial plan: Classic edge detection methods and built in open cv libraries were not providing proper performance regardless of how well the image was taken and preprocessed. Switched to an approach which detects color changes in a linear scan across resistor body. This method is working much better, though is dependent on quality of color classification Color classification was originally going to be performed…

Well, as we all know, this week has been crazy due to the outbreak of COVID-19 as a global pandemic. In order to do my part in preventing a worse spread of this disease, after returning from Spring Break, I spent most of my time preparing for a 2 week self-quarantine. After receiving guidance from the course staff as to how to move forward, we had multiple team discussions in which we rescoped the project to accommodate remote work with…

This week, I finished working on the object detection pipeline. Last week, I was struggling to properly filter our the background resistor board. I figured out the appropriate HSV values to filter it out, which should stay the same under these lighting conditions across images. I used CLAHE to reduce the effect of reflections of the resistors, morphological closing to close any holes that appeared in the resistors, and contouring to find and draw edges around the resistors. I cleaned…

For this week, I focused on figuring out how to detect resistors on a breadboard and get their locations as accurately and efficiently as possible. I considered standard deep learning approaches that would find bounding boxes around resistors it found in a given image. The three alternatives for  this were Faster RCNN –> the most accurate but slow and takes up memory YOLO –> much faster and lightweight alternative but accuracy is lower With both of these options as back…
