Add a detector to Simulink Model

Hi guys , i need to integrate this function in Simulink and i neet 2 inputs , one is a picture and second one is a detector to detect the stop sign in the picture but i coundn't add the Yolo detector to the simulink model , how can i do it if it's possible?

Thanks in advance!

function y = fcn(picture,detectorYolo2_stop)

[bboxes1,scores1,labels1] = detect(detectorYolo2_stop,picture);

picture = insertObjectAnnotation(picture,'Rectangle',bboxes1,cellstr(labels1));

y = picture;
