-## 近期更新（2021.1.11）
+## 近期更新（2021.1.18）
-#### Q3.1.32 能否修改StyleText配置文件中的分辨率？
+#### Q2.3.18: 在PP-OCR系统中，文本检测的骨干网络为什么没有使用SE模块？
-**A**：StyleText目前的训练数据主要是高度32的图片，建议不要改变高度。未来我们会支持更丰富的分辨率。
+**A**：SE模块是MobileNetV3网络一个重要模块，目的是估计特征图每个特征通道重要性，给特征图每个特征分配权重，提高网络的表达能力。但是，对于文本检测，输入网络的分辨率比较大，一般是640\*640，利用SE模块估计特征图每个特征通道重要性比较困难，网络提升能力有限，但是该模块又比较耗时，因此在PP-OCR系统中，文本检测的骨干网络没有使用SE模块。实验也表明，当去掉SE模块，超轻量模型大小可以减小40%，文本检测效果基本不受影响。详细可以参考PP-OCR技术文章，https://arxiv.org/abs/2009.09941.
-#### Q3.1.33 StyleText是否可以更换字体文件？
+#### Q3.3.27: PaddleOCR关于文本识别模型的训练，支持的数据增强方式有哪些？
-**A**：StyleText项目中的字体文件为标准字体，主要用作模型的输入部分，不能够修改。
+**A**：文本识别支持的数据增强方式有随机小幅度裁剪、图像平衡、添加白噪声、颜色漂移、图像反色和Text Image Augmentation（TIA）变换等。可以参考[代码](../../ppocr/data/imaug/rec_img_aug.py)中的warp函数。
-StyleText的用途主要是：提取style_image中的字体、背景等style信息，根据语料生成同样style的图片。
-#### Q3.1.34 StyleText批量生成图片为什么没有输出？
+#### Q3.3.28: 关于dygraph分支中，文本识别模型训练，要使用数据增强应该如何设置？
-**A**：需要检查以下您配置文件中的路径是否都存在。尤其要注意的是[label_file配置](https://github.com/PaddlePaddle/PaddleOCR/blob/dygraph/StyleText/README_ch.md#%E5%BF%AB%E9%80%9F%E4%B8%8A%E6%89%8B)。
+**A**：可以参考[配置文件](../../configs/rec/ch_ppocr_v2.0/rec_chinese_lite_train_v2.0.yml)在Train['dataset']['transforms']添加RecAug字段，使数据增强生效。可以通过添加对aug_prob设置，表示每种数据增强采用的概率。aug_prob默认是0.4.由于tia数据增强特殊性，默认不采用，可以通过添加use_tia设置，使tia数据增强生效。详细设置可以参考[ISSUE 1744](https://github.com/PaddlePaddle/PaddleOCR/issues/1744)。
-如果您使用的style_image输入没有label信息，您依然需要提供一个图片文件列表。
-#### Q3.1.35 怎样把OCR输出的结果组成有意义的语句呢？
+#### Q3.4.28: PP-OCR系统中，文本检测的结果有置信度吗？
-**A**：OCR输出的结果包含坐标信息和文字内容两部分。如果您不关心文字的顺序，那么可以直接按box的序号连起来。
+**A**：文本检测的结果有置信度，由于推理过程中没有使用，所以没有显示的返回到最终结果中。如果需要文本检测结果的置信度，可以在[文本检测DB的后处理代码](../../ppocr/postprocess/db_postprocess.py)的155行，添加scores信息。这样，在[检测预测代码](../../tools/infer/predict_det.py)的197行，就可以拿到文本检测的scores信息。
-如果需要将文字按照一定的顺序排列，则需要您设定一些规则，对文字的坐标进行处理，例如按照坐标从上到下，从左到右连接识别结果。
-对于一些有规律的垂类场景，可以设定模板，根据位置、内容进行匹配。
-例如识别身份证照片，可以先匹配"姓名"，"性别"等关键字，根据这些关键字的坐标去推测其他信息的位置，再与识别的结果匹配。
-#### Q3.1.36 如何识别竹简上的古文？
+#### Q3.4.29: DB文本检测，特征提取网络金字塔构建的部分代码在哪儿？
-**A**：对于字符都是普通的汉字字符的情况，只要标注足够的数据，finetune模型就可以了。如果数据量不足，您可以尝试StyleText工具。
-而如果使用的字符是特殊的古文字、甲骨文、象形文字等，那么首先需要构建一个古文字的字典，之后再进行训练。
+**A**：特征提取网络金字塔构建的部分:[代码位置](../../ppocr/modeling/necks/db_fpn.py)。ppocr/modeling文件夹里面是组网相关的代码，其中architectures是文本检测或者文本识别整体流程代码；backbones是骨干网络相关代码；necks是类似与FPN的颈函数代码；heads是提取文本检测或者文本识别预测结果相关的头函数；transforms是类似于TPS特征预处理模块。更多的信息可以参考[代码组织结构](./tree.md)。

 **A**：StyleText模型生成的数据主要用于OCR识别模型的训练。PaddleOCR目前识别模型的输入为32 x N，因此当前版本模型主要适用高度为32的数据。
 建议要合成的数据尺寸设置为32 x N。尺寸相差不多的数据也可以生成，尺寸很大或很小的数据效果确实不佳。
+#### Q2.3.18: 在PP-OCR系统中，文本检测的骨干网络为什么没有使用SE模块？
+**A**：SE模块是MobileNetV3网络一个重要模块，目的是估计特征图每个特征通道重要性，给特征图每个特征分配权重，提高网络的表达能力。但是，对于文本检测，输入网络的分辨率比较大，一般是640\*640，利用SE模块估计特征图每个特征通道重要性比较困难，网络提升能力有限，但是该模块又比较耗时，因此在PP-OCR系统中，文本检测的骨干网络没有使用SE模块。实验也表明，当去掉SE模块，超轻量模型大小可以减小40%，文本检测效果基本不受影响。详细可以参考PP-OCR技术文章，https://arxiv.org/abs/2009.09941.

 **A**：cosine_decay表示在训练的过程中，学习率按照cosine的变化趋势逐渐下降至0，在迭代轮数更长的情况下，比常量的学习率变化策略会有更好的收敛效果，因此在实际训练的时候，均采用了cosine_decay，来获得精度更高的模型。
+#### Q3.3.27: PaddleOCR关于文本识别模型的训练，支持的数据增强方式有哪些？
+**A**：文本识别支持的数据增强方式有随机小幅度裁剪、图像平衡、添加白噪声、颜色漂移、图像反色和Text Image Augmentation（TIA）变换等。可以参考[代码](../../ppocr/data/imaug/rec_img_aug.py)中的warp函数。
+#### Q3.3.28: 关于dygraph分支中，文本识别模型训练，要使用数据增强应该如何设置？
+**A**：可以参考[配置文件](../../configs/rec/ch_ppocr_v2.0/rec_chinese_lite_train_v2.0.yml)在Train['dataset']['transforms']添加RecAug字段，使数据增强生效。可以通过添加对aug_prob设置，表示每种数据增强采用的概率。aug_prob默认是0.4.由于tia数据增强特殊性，默认不采用，可以通过添加use_tia设置，使tia数据增强生效。详细设置可以参考[ISSUE 1744](https://github.com/PaddlePaddle/PaddleOCR/issues/1744)。

 正常来说，python端预测和C++预测文本是一致的，如果预测结果差异较大，
 建议首先排查diff出现在检测模型还是识别模型，或者尝试换其他模型是否有类似的问题。
 其次，检查python端和C++端数据处理部分是否存在差异，建议保存环境，更新PaddleOCR代码再试下。
 如果更新代码或者更新代码都没能解决，建议在PaddleOCR微信群里或者issue中抛出您的问题。

+```bash
+# 该代码需要在指定目录运行
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+python3 generate_multi_language_configs.py --help
+```
+下面以生成意大利语配置文件为例：
+##### 1. 生成意大利语配置文件测试现有模型
+如果您仅仅想用配置文件测试PaddleOCR提供的多语言模型可以通过下面命令生成默认的配置文件，使用PaddleOCR提供的小语种字典进行预测。
+```bash
+# 该代码需要在指定目录运行
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+# 通过-l或者--language参数设置需要生成的语种的配置文件，该命令会将默认参数写入配置文件
+python3 generate_multi_language_configs.py -l it
+```
+##### 2. 生成意大利语配置文件训练自己的数据
+如果您想训练自己的小语种模型，可以准备好训练集文件、验证集文件、字典文件和训练数据路径，这里假设准备的意大利语的训练集、验证集、字典和训练数据路径为：
+- 训练集:{your/path/}PaddleOCR/train_data/train_list.txt
+- 验证集:{your/path/}PaddleOCR/train_data/val_list.txt
+- 使用PaddleOCR提供的默认字典：{your/path/}PaddleOCR/ppocr/utils/dict/it_dict.txt
+- 训练数据路径:{your/path/}PaddleOCR/train_data
+使用以下命令生成配置文件：
+```bash
+# 该代码需要在指定目录运行
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+# -l或者--language字段是必须的
+# --train修改训练集，--val修改验证集，--data_dir修改数据集目录，-o修改对应默认参数
+# --dict命令改变字典路径，示例使用默认字典路径则该参数可不填
+python3 generate_multi_language_configs.py -l it \

 #### Multilingual Recognition Model（Updating...）
+**Note：** The configuration file of the new multi language model is generated by code. You can use the `--help` parameter to check which multi language are supported by current PaddleOCR.
+```bash
+# The code needs to run in the specified directory
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+python3 generate_multi_language_configs.py --help
+```
+Take the Italian configuration file as an example：
+##### 1.Generate Italian configuration file to test the model provided
+you can generate the default configuration file through the following command, and use the default language dictionary provided by paddleocr for prediction.
+```bash
+# The code needs to run in the specified directory
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+# Set the required language configuration file through -l or --language parameter
+# This command will write the default parameter to the configuration file.
+python3 generate_multi_language_configs.py -l it
+```
+##### 2. Generate Italian configuration file to train your own data
+If you want to train your own model, you can prepare the training set file, verification set file, dictionary file and training data path. Here we assume that the Italian training set, verification set, dictionary and training data path are:
+- Training set:{your/path/}PaddleOCR/train_data/train_list.txt
+- Validation set: {your/path/}PaddleOCR/train_data/val_list.txt
+- Use the default dictionary provided by paddleocr:{your/path/}PaddleOCR/ppocr/utils/dict/it_dict.txt
+- Training data path:{your/path/}PaddleOCR/train_data
+```bash
+# The code needs to run in the specified directory
+cd {your/path/}PaddleOCR/configs/rec/multi_language/
+# The -l or --language parameter is required
+# --train modify train_list path
+# --val modify eval_list path 
+# --data_dir modify data dir
+# -o modify default parameters
+# --dict Change the dictionary path. The example uses the default dictionary path, so that this parameter can be empty.
+python3 generate_multi_language_configs.py -l it \
+--train {path/to/train_list} \
+--val {path/to/val_list} \
+--data_dir {path/to/data_dir} \
