This is a lab we did an experiment using matlab simulink, i did the work with my pear and i want you to fill the lab sheet. I am going to paste the procedure that we did to get an idea. Also, will attach the sheet, lecture notes and some figures.

Okay, so the process we follow is this:
1. Draw circles of the PCB layout over the video feed.
2. Use homographic projection to make the PCB line up with the green circles.
3. Use bottom-hat filtering to isolate the tracks and holes from the rest of the board. A structuring element is chosen that is the same size as a hole.
4. Use a histogram and floating bar plot to find a threshold value to completely separate the copper and holes from the rest of the board. The threshold is applied using a relational operator and constant block.
5. Blob analysis is performed to try and find circles as big as the holes and draw a red circle over them.
6. If the thresholding, blob and bottom-hat settings are set correctly then the red circles should identify all of the holes, and line up with the green circles from the ‘small holes’ draw file.

I’m not sure if we can draw the red circles on the same video viewer as the green ones, but if not we can still compare them side-by-side

my pear sent me these words so please paraphrase them.

ask me if you have any question.
please start with the first part and i am going to update some stuff within few hours after my demonstration.
