## Overview

This is a desktop chest-X-ray pneumonia classifier. The user selects an image, the app loads the saved model, preprocesses the image, predicts a class, and announces the result through speech. A separate notebook-derived script trains and saves the model. The README gives only the project title, so these capabilities and connections are inferred from the supplied source; the generated model file and dataset are not in the tree.

Main entry points: [`chest_xray.py`](https://github.com/chando0185/chest_x_ray_detection/blob/master/chest_xray.py) (Image selection), [`Untitled.py`](https://github.com/chando0185/chest_x_ray_detection/blob/master/Untitled.py) (VGG16 training)
