Image Processing Basis

This repository provides basic image processing practice focusing on:

• 🚩 Image Rotation
• 🚩 Image Scaling

implemented in C++ for foundational understanding.

🚀 Quick Start

1️⃣ Clone Repository

git clone https://github.com/M-H482/image-processing-basis.git
cd image-processing-basis

2️⃣ Image Rotation

Rotates input images by a specified angle (in degrees), using the image center as the rotation center.

cd image_rotation
bash build.sh       # Build the rotation executable
bash run.sh         # Run the rotation demo

3️⃣ Image Scaling

Resizes input images to specified scales.

cd image_scaling
bash build.sh       # Build the scaling executable
bash run.sh         # Run the scaling demo

4️⃣ Affine Transformation

Implementing rotation of any angle around any center using an affine matrix

cd affine_transformation
bash build.sh       # Build the scaling executable
bash run.sh         # Run the scaling demo

🛠 Requirements

Linux with g++

OpenCV

📈 Future Plans

Add a demo of FFT.
