 * detail_method: Edge processing methods. provides VITMatte, VITMatte(local), PyMatting, GuidedFilter. If the model has been downloaded after the first use of VITMatte, you can use VITMatte (local) afterwards.
 * detail_erode: Mask the erosion range inward from the edge. the larger the value, the larger the range of inward repair.
