MATLAB Implementation for Optical Flow Field Calculation

The following MATLAB code implements optical flow field calculation, which can be used to compute pixel motion in video sequences. Optical flow field computation represents a fundamental technique in computer vision and image processing, enabling analysis of object motion and behavior patterns. This method finds applications in video compression, motion estimation, and activity recognition systems. The implementation utilizes gradient-based approaches (such as Lucas-Kanade or Horn-Schunck algorithms) that calculate motion vectors by analyzing spatial and temporal intensity derivatives between consecutive frames. Key functions include frame differencing, gradient computation, and motion vector regularization to handle various motion patterns. This code provides a practical foundation for understanding optical flow calculation methodologies and principles, allowing researchers and developers to apply these techniques to their projects and research studies. The implementation includes parameter optimization suggestions for different video characteristics and motion scenarios.
