Hello, I am required to able to detect a pattern, which is made of three round colored circle made up of green red and blue. The position of the circle will determine the name of the pattern. hence, if the video cam goes over pattern 1, which consists of only 3 red circles, it will be able to detect and display in the console pattern 1. I have complete the detect color but not yet able to detect the pattern of the color. I know I have to create a template of the pattern, but I am not sure where to start. Is there any simple examples of pattern recognition, I can try that later I may be able to modify to fit my code?
