The researchers studied different edge detection algorithms in MATLAB and found that Roberts, Sobel, and Kirsch operators are the most accurate. To enhance real-time performance, they designed an FPGA-based system with image buffer, operator calculation, and threshold processing modules. Testing showed that the Sobel operator performs best on limited hardware resources.
