This dataset contains 196 images of raccoons and 213 bounding boxes (some images have two raccoons). This is a single class problem, and images vary in dimensions. It's a great first dataset for getting started with object detection.
This dataset was originally collected by Dat Tran, released with MIT license, and posted here with his permission.
Per Roboflow's Dataset Health Check, here's how images vary in size:
This dataset is a great starter dataset for building an object detection model. Dat has written a comprehensive tutorial here.
