Pretty interesting talk on how to prevent squirrels from stealing bird food using python and computer vision.
Steps to recognize a squirrel on a picture:
- Subtract background.
- Compute average value of each pixel over time to build a background profile.
- Detect blobs.
- Discriminate blobs. Distinguish between squirrels from other things. The
author used support vector machines.
- Blob size
- Color histograms
- Entropy detection (squirrel tail)
