Hello, thank you for translating this matlab eval_function into Python. I have some question about your edge_eval_python, how do I use this function to evaluate my dataset? I found that the GT files in the BSDS dataset are divided into 5 matrices, and in your edge_eval_python, five matrices are added up to make one matrix, as the final GT. But in my dataset, the GT files are just some png files, what should I do?
