Thanks for the code!
In the detection method of the FaceDetection class you might want to crop out faces on the original image instead of img_with_detections:

def detection(self):
    faces_crop = []
    for (x, y, w, h) in self.faces:  
        obj = self.img_original[y:y + h, x:x + w]
        faces_crop.append(obj)
        cv2.rectangle(self.img_with_detections, (x, y), (x+w, y+h), (0, 255, 0), 2)
        
    return faces_crop

Otherwise in the case of overlapping boxes, you get cropped images containing lines from other detection boxes.

I want to ask that why the label y needs to substract 48 and divide by 48 like:
y = (y - 48) / 48
