Web19 jun. 2024 · For each class, we first identify the indices of that class using pred_inds = (pred == sem_class) and target_inds = (label == sem_class). The resulting pred_inds and target_inds will have 1 at pixels labelled as that particular class while 0 for any other class. Then, there is a possibility that the target does not contain that particular class ...
