videoFileReader = vision.VideoFileReader('h1.avi'); videoFrame = step(videoFileReader); figure, imshow(videoFrame) faceDetector = vision.CascadeObjectDetector; bbox = step(faceDetector, videoFrame); videoOut = insertObjectAnnotation(videoFrame,'rectangle',bbox,'Face'); figure, imshow(videoOut), title('Detected face')

Use an if statement to check if bbox is empty. If it is empty, then no face is detected. If not, then a face is detected.
