从结果中可以看到对预训练模型不做修改，只根据场景下的具体情况进行后处理的修改就能大幅提升端到端指标到78.27%，在CCPD数据集上进行 fine-tune 后指标进一步提升到87.14%, 在经过量化训练之后，由于检测模型的recall变高，指标进一步提升到88%。但是这个结果仍旧不符合检测模型+识别模型的真实性能(99%*94%=93%)，因此我们需要对 base case 进行具体分析。

在PP-StructureV2中，我们发布基于PP-PicoDet的轻量级版面分析模型，并针对版面分析场景定制图像尺度，同时使用FGD知识蒸馏算法，进一步提升模型精度。最终CPU上`41ms`即可完成版面分析过程(仅包含模型推理时间，数据预处理耗时大约50ms左右)。在公开数据集PubLayNet 上，消融实验如下：
