function displayTrackingResults()
        % Convert the frame and the mask to uint8 RGB.
        frame = im2uint8(frame);
        mask = uint8(repmat(mask, [1, 1, 3])) .* 255;

        minVisibleCount = 8;
        if ~isempty(tracks)

            % Noisy detections tend to result in short-lived tracks.
            % Only display tracks that have been visible for more than
            % a minimum number of frames.
            reliableTrackInds = ...
                [tracks(:).totalVisibleCount] > minVisibleCount;
            reliableTracks = tracks(reliableTrackInds);

            % Display the objects. If an object has not been detected
            % in this frame, display its predicted bounding box.
            if ~isempty(reliableTracks)
                % Get bounding boxes.
                bboxes = cat(1, reliableTracks.bbox);

                % Get ids.
                ids = int32([reliableTracks(:).id]);

                % Create labels for objects indicating the ones for
                % which we display the predicted rather than the actual
                % location.
                labels = cellstr(int2str(ids'));
                predictedTrackInds = ...

            end
        end

        % Display the mask and the frame.
        obj.maskPlayer.step(mask);
        obj.videoPlayer.step(frame);

hello , i fund this error

Undefined function or variable 'frame'.

Error in displayTrackingResults (line 4)

frame = im2uint8(frame);

When it says

        % Convert the frame and the mask to uint8 RGB.
        frame = im2uint8(frame);

frame is not defined at that point. It looks like it's supposed to be an RGB image that was passed in. I think mask and tracks were also supposed to be passed in.

You can try this deep learning based face detector: https://github.com/matlab-deep-learning/mtcnn-face-detection

It outputs the location of eyes, nose and mouth corners as well as the face bounding box.
