I'm trying to detect silver coins on a carpet (I know what the carpet looks like). The camera is going to be mounted to an iRobot Create. I took 20 pictures of the coins (quarters, nickels and dimes) at approximately the angle the camera will be mounted at on the Create (it isn't mounted yet). I also took 20 pictures of the carpet without the coins to use as the negative images. I ran the command: Then I ran: It only completed three stages then said the max false alarm rate had been reached. When I used opencv's facedetect to test the .xml file, there were many circles where there we no coins: Am I taking the right approach to trying to detect coins on a carpet? Thanks! |
