① About the App This is an app that extracts edges from images and calculates approximations for straight lines. It's available on Streamlit, so please give it a try. https://imageline-rcqzybrulvdkugwmjmz4gp.streamlit.app/
② Notes 1:To extract edges cleanly, please use images with transparent backgrounds. 2:The algorithm for calculating the approximation formula is created using ChatGPT. 3:Although Fourier series transformation is desired, the app calculates approximations for straight lines due to the heavy computational load of the process.
