Real-time Mouse Coordinate Tracking on Images in MATLAB GUI

In MATLAB, through graphical user interface (GUI) development, real-time coordinate acquisition is achievable when moving the mouse over displayed images. This functionality is implemented using callback functions such as 'WindowButtonMotionFcn' or image-specific 'ButtonDownFcn' to track pointer movement. The coordinates can be extracted through the 'CurrentPoint' property of the axes object, which returns the (x,y) position relative to the image data units. This feature significantly enhances workflow efficiency by enabling precise localization of specific image points. Beyond basic coordinate tracking, developers can extend this functionality for advanced image processing tasks - such as marking regions of interest using bounding boxes, implementing click-and-drag selection tools, or calculating distances between points using Euclidean distance algorithms. The coordinate data can be seamlessly integrated with image processing functions like 'imcrop' for region extraction or 'impixel' for color value retrieval. This capability forms the foundation for interactive image analysis applications, making complex operations more intuitive and accessible.
