Detailed Documentation
Interactive image point selection can be implemented using MATLAB, where users obtain coordinate points through mouse clicks. This process enables precise identification of key points on images and plays a crucial role in subsequent analysis and processing workflows. The implementation typically utilizes MATLAB's built-in functions such as ginput() for coordinate collection, which returns the (x,y) coordinates of mouse clicks on the displayed image. Additional image processing algorithms and techniques can be integrated based on specific requirements, including coordinate validation, point filtering, or automatic point refinement algorithms to optimize the accuracy of selected coordinates. The collected points can be stored in arrays for further geometric analysis, measurement calculations, or as reference points for image registration and transformation operations.
