Find blob first then find circle

My use case is to have a mini rover chase after red ball (circle). I was using find blob to detect the red initially, and obviously it wasn’t good enough as it pick up so many other reds. So I decided to use two level detection: 1st check the red blob then windowing the blob ROI, 2nd check the circl...

Re: Template matching with framesize QVGA

Here you go. I wanted to post the *.pgm files but i don't know how to attach. As for the uart command from arduino, it's just a 2-bytes ASCII coming through uart to H7. I hope you can reproduce this issue as my code seems unstable, sometimes the snapshot() will take very long time to capture which r...

Template matching with framesize QVGA

I'm using the template matching example in IDE as reference for my application of H7 receiving command from arduino via uart. I had the sensor framesize set at QVGA and using search_DS for template. It works for some period of time until i disconnect the H7 (in the IDE) and reconnect trying to run a...
