This project builds artificial neural network in Python using NumPy from scratch in order to do an image classification application for the Fruits360 dataset. Just 4 classes are used from such a dataset which are Apple Braeburn, Lemon Meyer, Mango, and Raspberry.

At first, features are extracted from the dataset using the extract_features.py script. This file is expected to be located at a directory in which there are 4 folders holding the images of the 4 classes. The folders are named apple, lemon, mango, and raspberry. The script loops through the images within the 4 folders for calcualting the features which are the color histogram of the hue channel of the HSV color space. The script saves 2 files. The first one holds the features of all samples and the second one is the class labels of the samples.

After preparing the training data (inputs features and class labels), next is to implement the ANN and train it according to such data. This is done using the ann_numpy.py script.
