We can build a CNN that has 2 branches: one of them performs a classification of the object and one of them finds the specifications of the bounding box. This architecture won't be good when we have multiple objects in the photo, and this is why we move to YOLO architectures where each part of the image would be studied alone in order to detect the different objects.

Mask R-CNN:

Extension of Faster R-CNN.
Adds a mask prediction branch for instance segmentation.
High accuracy and versatility.

YOLO (You Only Look Once):

Single-stage detector.
Real-time detection.
Unified detection and classification.

    For object detection we can use the following architectures:

    • You only look once (YOLO)
    • single shot detector (SSD) like mobilenet
    • RCNN like InceptionResNet

        How does YOLO perform object detection?

        Select one of the following options:
        • A.

          By using a cascade of classifiers to refine the detection

        • B.

          By dividing the image into a grid and predicting bounding boxes and probabilities for each grid cell

        • C.

          By scanning an image with a sliding window

        • D.

          By first identifying objects then dividing the image into a grid
