This week I spent much time and made good progress on the computer vision portion of our project! Originally in our schedule, I am to first do the individual component detection, but this week I opted to complete the full circuit detection in which I parse the original input image to generate the sub images for each component. I opted to do this because this will make it easier for me to test the individual circuit detection because I can upload drawings of full circuits instead of having to take individual photos of components. Also, by doing this I generate photos of the components that are more appropriately sized.<\/p>\n

Here is the sub-image generation in action:<\/p>\n

First the original image is greyscaled:<\/p>\n

\"\"<\/p>\n

Then do some thresholding:<\/p>\n

\"\"<\/p>\n

Then apply a median blur (see how just the nodes are left!):<\/p>\n

\"\"\u00a0<\/span><\/p>\n

Then use Hough Circle transform to find all the nodes (circles in white):<\/p>\n

\"\"<\/p>\n

Then (skipping some steps here) generate individual component images by calculating bounding boxes for each edge (connection between nodes):<\/p>\n

\"\" \u00a0<\/span>\u00a0<\/span><\/p>\n

I also implemented the brute force feature matching to figure out the best matched component given an input image and a dataset of images. It actually worked better than I expected, successfully classifying 3\/3 sub images, but obviously I need to do more testing. There is definitely a lot of stuff I want to tune still, and I want to try adding some blurring and more image preprocessing to see if the results are more definitive.<\/p>\n

I am definitely on schedule. I purposely worked a lot this week because next week I have several midterms that will eat up my time, as well as the design report.<\/p>\n

My next steps are to integrate the sub image generation and component detection so that I can work on the full-circuit re-creation and netlist generation. After this infrastructure is completed, I will start to fine tune parameters and whatnot in each step of the process.<\/p>\n","protected":false},"excerpt":{"rendered":"
