<h1>Surface Roughness Image Analysis</h1>

<h2>Description</h2>
<p>Surface Roughness Image Analysis is a Python program developed for the analysis and processing of images related to surface roughness of microscopic specimens. It provides tools to calculate elements like waviness, roughness, and profile, enabling comprehensive information about the irregularity of the specimen's surface. This project was developed as part of a Ph.D. thesis in additive manufacturing.</p>
