= Homomorphic filtering
{wiki=Homomorphic_filtering}
Homomorphic filtering is a signal processing technique used primarily in image enhancement. The main idea behind homomorphic filtering is to separate an image into its illumination and reflectance components, allowing for the manipulation of these components separately to improve image quality. \#\#\# How it Works: 1. **Logarithmic Transformation**: The first step in homomorphic filtering involves taking the logarithm of the image intensity values. This transformation effectively linearizes the multiplicative relationship between the illumination and reflectance in the image.
