Array indices must be positive integers or logical values in facial detection

3 Ansichten (letzte 30 Tage)
Good afternoon,
I am not sure why i am getting this error returned when i am using the following code;
faceDetector = 'vision.CascadeObjectDetector';
I = imread('INSERT PICTURE LOCATION HERE');
bboxes = faceDetector(I);
IFaces = insertObjectAnnotation(I,'rectangle',bboxes,'Face');
figure
imshow(IFaces)
title('Detected faces');
I am not sure what this error means as the pixel values i am using are all positive values so I am very confused. What can I do to achieve a successful output?
Thanks.

Hi Evan,
I think you got confused in defining a facedetector. Check out the following code, this might help you.
faceDetector = vision.CascadeObjectDetector(); % Correct way to define this object.
I = imread('INSERT PICTURE LOCATION HERE'); % Read an image.
bboxes = faceDetector(I); % call the function.
IFaces = insertObjectAnnotation(I,'rectangle',bboxes,'Face');
figure
imshow(IFaces)
title('Detected faces');
Also check out this resource page in case you stuck somewhere.
I hope this helps.
Cheers.
