OpenCV with Python Blueprints

Putting it all together

To run our app, we will need to execute the main function routine (in chapter6.py). It loads the data, trains the classifier, evaluates its performance, and visualizes the result.

But first, we need to import all the relevant modules and set up a main function:

import numpy as np

import matplotlib.pyplot as plt
from datasets import gtsrb
from classifiers import MultiClassSVM


def main():

Then, the goal is to compare classification performance across settings and feature extraction methods. This includes running the task with both classification strategies, one-vs-all and one-vs-one, as well as preprocessing the data with a list of different feature extraction approaches:

 strategies = ['one-vs-one', 'one-vs-all']features = [None, ...
