请问作者,Parsing YOLO Region output在树莓派上耗时达到65ms左右,严重干扰了实时检测效果,请问这部分是解析推理后的数据吗,有没有什么简化的方法呢?

对,Parsing YOLO Region output是将神经网络的输出进行后处理,得到最终的检测框。 这个是挺难优化的。耗时的主要是NMS非极大值抑制,你可以看看有没有效率更高的NMS算法 。 另外C++的推理会比python快些。

作者大哥,这个Parsing YOLO Region output貌似不包含NMS,是对图像划分为13×13个网格进行分析,单纯是循环次数太多13×13×3导致我耗时过大。在电脑CPU上处理还好,在嵌入式上就很慢了。
