Automate Image Cropping in Python

Are you looking to crop specific images in a folder continuously while maintaining the same size settings? If you’re dealing with multiple images and need to automate the process, you’re in the right place! This guide will guide you step-by-step on how to do just that using Python and OpenCV.

The Problem

Many users, especially those new to programming, face challenges when trying to manipulate multiple images in a directory. The common issues encountered include:

Needing to manually edit paths for each image.

Only previewing output images without saving them.

Not having a clear understanding of how to apply a consistent cropping size across several images.

If you've experienced these problems, don't worry! Below, we’ll outline a solution that will make your life much easier.

The Solution

Requirements

Before we start, ensure you have Python and OpenCV installed on your machine. You can install OpenCV via pip if you haven’t already:
