Chapter 10

Support code for Chapter 10: Pattern Recognition & Computer Vision

Data

This chapter relies on a publicly available dataset (which can be downloaded using the download.sh script inside the data/ directory) as well the dataset that is packaged with the repository at ../SimpleImageDataset/.

Running download.sh will retrieve the other dataset into a directory AnimTransDistr/.

Scripts

figure10.py

Just paste two images next to each others

features.py

Contains the color histogram function from the book as well as a simple wrapper around mahotas.texture.haralick

simple_classification.py

Classify SimpleImageDataset with texture features + color histogram features

large_classification.py
