Introduction

In today’s competitive stone industry, efficiency and precision are key to staying ahead. Manual sorting of stone tiles, especially mint sandstone from Gwalior, is time-consuming, error-prone, and costly. Enter the PHP Color Sorter – an AI-powered web application that revolutionizes how stone businesses handle color classification and defect detection.
