Resource Overview
MATLAB-based image annotation tool for extracting and labeling regions of interest in images, facilitating subsequent analysis. The program includes functions for interactive region selection and annotation storage, with compatibility for various image formats.
Detailed Documentation
This documentation explains how to use MATLAB's image annotation capabilities to extract and label regions of interest in images, supporting subsequent analytical processes. The MATLAB implementation utilizes built-in functions like imrect, imfreehand, and insertShape for interactive region selection and visualization. Beyond basic annotation, the framework supports additional image processing operations including filtering techniques (medfilt2, imgaussfilt) and edge detection algorithms (Canny, Sobel through edge function). The code structure allows for batch processing through imread and imwrite functions, with annotation data exportable in MATLAB's native format or compatible with external analysis tools. By leveraging MATLAB's comprehensive image processing toolbox, users can perform end-to-end image analysis from preprocessing to advanced feature extraction.
