This model presents how one may be able to detect whether an image is in or out of focus using the FFT. Stateflow® is used to manage state behavior; the model also makes use of Embedded MATLAB and integration of legacy C code. When running the model, you may need to configure the Image Acquisition block to operate with your camera. If you do not have a camera but would like to experiment with the out-of-focus detection model, you can use the included video file.
