Exercise: Download a Pretrained Object Detection CNN

Explore how to download and utilize a pretrained Faster-RCNN convolutional neural network for object detection. Learn to create preprocessing pipelines, run inference on images, and annotate detected objects with bounding boxes, filtering results by confidence levels.

We'll cover the following...

Problem statement

In this lesson, we’ll download a pretrained CNN for object detection. We’ll test it with some images and filter the results by comparing the confidence level with a preset threshold.

Launch the Jupyter Notebook below and follow the instructions.

Instructions:

  • The comment lines starting with # >>> indicate that you must edit the cell.

  • Replace the None values with the correct function calls.

The main steps that you’ll have to complete are:
