Try vision.CascadeObjectDetector in the Computer Vision System Toolbox. If detecting the face does not work well because of the helmet, you can also try detecting the eyes and/or the nose. Some combination of these detectors may do the job. To increase sensitivity, you can try decreasing the 'ScaleFactor' parameter.
Alternatively, you can try to detect the faces using the color of the pixels.
