This project focused on creating high-quality annotated image datasets to support machine learning models for image classification in the healthcare sector. The primary objective was to label and categorize medical images—such as X-rays, CT scans, MRI images, or dermatological images—into clinically relevant classes (e.g., normal vs. abnormal, disease type, severity level). The annotations were designed to help train and validate AI models used for early detection, diagnosis support, and clinical decision-making. The project involved reviewing large volumes of anonymized medical images and applying standardized annotation guidelines developed in collaboration with domain experts. Labels were assigned based on visual indicators, predefined medical criteria, and metadata provided with each image. Multiple quality-control steps were implemented, including cross-review, consistency checks, and error correction, to ensure annotation accuracy and reduce bias.
