Subject: Numerical Methods Materials: Finite Difference Method Please build a program using python/other language for detecting the edge of objects in the black and white image. The edge detection must use the gradient with finite differences. Notes: Please give me the code & the results, as well as a detailed explanation of the code and detailed explanations of the result of edge detecting, so I could have understanding of the materials, thank you very much. Picture: I googled this picture below by writing "black and white picture "and "vase black and white still life
