Try running stdfilt() to look for smooth regions. limit the region(s) it finds to the area within some reasonable sized region right above the eyes. Why do you need the forehead?

在 MATLAB Online 中打开

this is the code

   rgbImage =imread('6.jpg');
% imshow(rgbImage);
faceDetector = vision.CascadeObjectDetector;
faceDetector.MergeThreshold=16; 
  bboxes = step(faceDetector, rgbImage);
  IFaces = insertObjectAnnotation(rgbImage, 'rectangle', bboxes, 'Face');
   figure, imshow(IFaces), title('Detected faces');
      faceimage = imcrop(rgbImage,bboxes);
        imshow(faceimage);
