请问大佬mean和norm怎么获得呀

yolov5.register_custom_layer("YoloV5Focus", YoloV5Focus_layer_creator); yolov5.opt.num_threads = ncnn::get_big_cpu_count(); yolov5.opt.blob_allocator = &blob_pool_allocator; yolov5.opt.workspace_allocator = &workspace_pool_allocator;

char parampath[256];
char modelpath[256];
sprintf(parampath, "%s.param", modeltype);
sprintf(modelpath, "%s.bin", modeltype);

yolov5.load_param(parampath);
yolov5.load_model(modelpath);

target_size = _target_size;

mean_vals[0] = 1 / 255.f;
mean_vals[1] = 1 / 255.f;
mean_vals[2] = 1 / 255.f;
norm_vals[0] = 0;
norm_vals[1] = 0;
norm_vals[2] = 0;

还有就是这一段的mean和norm我看没有别的地方引用，是不是没啥用处呀

是这个，默认使用ncnn的固定参数
