WitrynaIn this recipe, you are going to implement a feature-based image classifier using the scikit-image and scikit-learn library functions. A multiclass logistic regression (softmax regression) classifier will be trained on the histogram of oriented gradients ( HOG) descriptors extracted from the training images.
