How to load Matlab .mat files in Python

Matlab is a really popular platform for scientific computing in the academia. I’ve used it my throughout my engineering degree and chances are, you will come across .mat files for datasets released by the universities.

This is a brief post which explains how to load these files using python, the most popular language for machine learning today.

The data

I wanted to build a classifier for detecting cars of different models and makes and so the Stanford Cars Dataset appeared to be a great starting point. Coming from the academia, the annotations for the dataset was in the .mat format. You can get the file used in this post here.

Loading .mat files

Scipy is a really popular python library used for scientific computing and quite naturally, they have a method which lets you read in .mat files. Reading them in is definitely the easy part. You can get it done in one line of code:

from scipy.io import loadmat
annots = loadmat('cars_train_annos.mat')

Well, it’s really that simple. But let’s go on and actually try to get the data we need out of this dictionary.

Formatting the data

The loadmat method returns a more familiar data structure, a python dictionary. If we peek into the keys, we’ll see how at home we feel now compared to dealing with a .mat file:

annots.keys()
> dict_keys(['__header__', '__version__', '__globals__', 'annotations'])

Looking at the documentation for this dataset, we’ll get to learn what this is really made of. The README.txt gives us the following information:

This file gives documentation for the cars 196 dataset.

Descriptions of the files are as follows:
-cars_meta.mat:
Contains a cell array of class names, one for each class.
-cars_train_annos.mat:
Contains the variable ‘annotations’, which is a struct array of length
num_images and where each element has the fields:
bbox_x1: Min x-value of the…
