Incorrect Coordinates When Creating Bounding Box in Custom Detection Application

• Function used to arrange the model architecture to generate bounding box with correct coordinates as below: 

  detections = result.reshape(-1, 5) 
       for i, detection in enumerate(detections): 
           xmin, ymin, xmax, ymax, confidence = detection 
           if confidence > 0.2: 
               xmin = int(max((xmin * image.shape[1]), 10)) 
               ymin = int(max((ymin * image.shape[0]), 10)) 
               xmax = int(min((xmax * image.shape[1]), image.shape[1] - 10)) 
                ymax = int(min((ymax * image.shape[0]), image.shape[0] - 10)) 

• Obtained incorrect coordinates of the bounding box. 

Set the margin at least ten pixels from the image edge when drawing the bounding box as below:

xmin = int(max(xmin, 10))

ymin = int(max(ymin, 10))

xmax = int(min(xmax, image.shape[1] - 10))

ymax = int(min(ymax, image.shape[0] - 10))
