Image classification, a fundamental annotation technique, involves categorizing medical images based on specific attributes or characteristics. This image annotation type empowers healthcare professionals and researchers to make informed decisions by quickly identifying and understanding key features of the image.
1.    Image Classification:
•    Image classification annotation involves labeling an image to categorize them into specific classes, such as normal and abnormal conditions.
2.    Object Detection:
•    Object detection annotation identifies and label the data of specific objects or anomalies within medical images, aiding in the localization of abnormalities.
3.    Medical Image Data Segmentation:
•    Medical image segmentation annotation involves delineating and labeling the boundaries of organs or structures within an image, providing a detailed understanding of the region of interest.
4.    Point Annotation:
•    Point annotation focuses on identifying specific points within an image, crucial for pinpointing anomalies at precise locations.
