Image Processing Filters Collection

This repository contains a collection of Python scripts for popular image enhancement and pansharpening filters, tested on Image_HW2.tif.

Main Filters

• Edge Enhancement: laplacian_enhancement.py, sobel_enhancement.py, advanced_edge_filters.py, highpass_filter.py
• Noise Reduction: gaussian_blur_filter.py, median_filter.py, bilateral_filter.py
• Contrast Enhancement: histogram_equalization.py, adaptive_histogram_equalization.py, contrast_stretching.py
• Brightness: gamma_log_transforms.py
• Sharpening: highboost_unsharp.py, highpass_filter.py
• Pansharpening: pansharpening_methods.py

Usage

Run all filters:

python run_all_filters.py

Run a single filter:

python gaussian_blur_filter.py
python laplacian_enhancement.py
# ...

Requirements

numpy
rasterio
scipy

Install:

pip install numpy rasterio scipy

Notes

• All scripts use Image_HW2.tif as input.
• Output files: Image_HW2_[filter]_[params].tif
• See each script for parameter options.
• run_all_filters.py runs all and summarizes results.
