通用手写文字擦除A榜2，B榜第3方案

一、赛题背景

随着技术发展，OCR扫描在学习、办公等众多场景中被使用，通过技术和算法，对扫描获得的纸张文档上的手写笔迹还原修复，恢复文件本身的样子，使得人们的使用体验越来越便捷。上一期比赛，我们举办了试卷场景下的手写文字擦除，帮助学生党们擦除试卷上的笔迹。本次比赛，我们诚邀各位选手并拓宽场景：不限于试卷，对通用文件上的手写笔迹进行擦除后还原文件，帮助更多人解决扫描上的问题。

二、数据分析

本次比赛的数据集分别为两类，第一类是上期比赛使用的试卷类型图片1081张，第二类是包含手写字迹的类似PDF文档图片12万张左右。

缩减二类数据：
首先考虑到二类图片的数量巨大，在有限显存下过大的训练数据集对精度的提高是有限的，其次观测到测试数据集的试卷类型图片所占比重是0.4，所以为了平衡两类型的数据，因此二类图片只选取了二十分之一（6346张）用作训练。

扩增一类数据：
接着考虑到一类试卷类型图片的特征基本上都为边缘纹理信息（不管是印刷体，手写体还是批改符号），并且此类图片梯度计算对颜色的依赖性不强，而颜色本身，非常容易受到光照等因素的影响，同类的物体颜色有很多变化，所以颜色本身可能难以提供关键信息。所以将此类图片灰度化后加入原始数据集进行数据增强。最终训练集中此类图片总共是2162张图片（1081张原图+1081张灰度图）。也进一步的平衡了两类型的数据。一类图片的mask采用比赛baseline中mask.

三、模型设计

网络模型，是基于本次比赛的baseline进行了改进。

Refinement：
首先参考了上一期手写文字擦除第一名的方案，将Refinement部分替换成了基于Non-Local的深度编解码网络。

Coarse-erasure：
然后考虑到本次比赛有把推理时间算作指标，为了轻量化网络模型，所以在Coarse-erasure不再使用swin-T（经过对比swin-T的优化效果较小），而在最深层网络引入ASPP+CBAM，在skip connection处引入了SE attention,通过扩大感受野和注意力来增强特征提取。

模型：

四、调参优化策略

损失函数：L1 loss function + BCE loss function；

学习率调度：StepDecay

训练大致分为三阶段：

第一阶段先从512x512的patch_size开始训练500Epoch,batch_size=4,lr=1e-4；

第二阶段再从256x256的patch_size开始训练500Epoch,batch_size=16,lr=5e-5；

第三阶段再从512x512的patch_size开始训练500Epoch,batch_size=2,lr=1e-5；

由于网络较深，为了模型真正收敛，后期模型改进后又多次进行多阶段的训练，没有最好只有更好，就是练！

五、测试细节

测试trick：
分块测试，为了减少预测的时间，把图像切分为768x768的小块进行预测。
