+# [MaskRCNN Description](#contents)
+MaskRCNN is a conceptually simple, flexible, and general framework for object instance segmentation. The approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance. The method, called Mask R-CNN, extends Faster R-CNN by adding a branch for predicting an object mask in
+parallel with the existing branch for bounding box recognition. Mask R-CNN is simple to train and adds only a small overhead to Faster R-CNN, running at 5 fps. Moreover, Mask R-CNN is easy to generalize to other tasks, e.g., allowing to estimate human poses in the same framework.
+It shows top results in all three tracks of the COCO suite of challenges, including instance segmentation, boundingbox object detection, and person keypoint detection. Without bells and whistles, Mask R-CNN outperforms all existing, single-model entries on every task, including the COCO 2016 challenge winners. 
+
+# [Model Architecture](#contents)
+MaskRCNN is a two-stage target detection network. It extends FasterRCNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition.This network uses a region proposal network (RPN), which can share the convolution features of the whole image with the detection network, so that the calculation of region proposal is almost cost free. The whole network further combines RPN and mask branch into a network by sharing the convolution features.

+# [Dataset](#contents)

-## Requirements
+```bash
+pip install Cython
+pip install pycocotools
+pip install mmcv=0.2.14
+```
+  
+  
+# [Quick Start](#contents)
 
-- Install [MindSpore](https://www.mindspore.cn/install/en).
+1. Download the dataset COCO2017.
 
-- Download the dataset COCO2017.
+2. Change the COCO_ROOT and other settings you need in `config.py`. The directory structure should look like the follows:
+    ```
+    .
+    └─cocodataset
+      ├─annotations
+        ├─instance_train2017.json
+        └─instance_val2017.json
+      ├─val2017
+      └─train2017
+    ```
+     If you use your own dataset to train the network, **Select dataset to other when run script.**
+    Create a txt file to store dataset information organized in the way as shown as following:
+    ```
+    train2017/0000001.jpg 0,259,401,459,7 35,28,324,201,2 0,30,59,80,2
+    ```
+    Each row is an image annotation split by spaces. The first column is a relative path of image, followed by columns containing box and class information in the format [xmin,ymin,xmax,ymax,class]. We read image from an image path joined by the `IMAGE_DIR`(dataset directory) and the relative path in `ANNO_PATH`(the TXT file path), which can be set in `config.py`. 
 
-- We use coco2017 as training dataset in this example by default, and you can also use your own datasets.
+3. Execute train script. 
+    After dataset preparation, you can start training as follows:
+    ```
+    # distributed training
+    sh run_distribute_train.sh [RANK_TABLE_FILE] [PRETRAINED_CKPT]
+     
+    # standalone training
+    sh run_standalone_train.sh [PRETRAINED_CKPT]
+    ```
+    Note:
+    1. To speed up data preprocessing, MindSpore provide a data format named MindRecord, hence the first step is to generate MindRecord files based on COCO2017 dataset before training. The process of converting raw COCO2017 dataset to MindRecord format may take about 4 hours.
+    2. For distributed training, a [hccl configuration file](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/utils/hccl_tools) with JSON format needs to be created in advance.
+    3. PRETRAINED_CKPT is a resnet50 checkpoint that trained over ImageNet2012.
 
-    1. If coco dataset is used. **Select dataset to coco when run script.**
-        Install Cython and pycocotool, and you can also install mmcv to process data.
+4. Execute eval script.
+   After training, you can start evaluation as follows:
+   
+   ```bash
+   # Evaluation
+   sh run_eval.sh [VALIDATION_JSON_FILE] [CHECKPOINT_PATH]
+   ```
+   Note: 
+   1. VALIDATION_JSON_FILE is a label json file for evaluation.
 
-        ```
-        pip install Cython
+# [Script Description](#contents)
 
-        pip install pycocotools
+## [Script and Sample Code](#contents)
 
-        pip install mmcv
-        ```
-        And change the COCO_ROOT and other settings you need in `config.py`. The directory structure is as follows:
-
-
-        ```
-        .
-        └─cocodataset
-          ├─annotations
-            ├─instance_train2017.json
-            └─instance_val2017.json
-          ├─val2017
-          └─train2017
-    
-        ```
-        Notice that the coco2017 dataset will be converted to MindRecord which is a data format in MindSpore. The dataset conversion may take about 4 hours.
-    2. If your own dataset is used. **Select dataset to other when run script.**
-        Organize the dataset infomation into a TXT file, each row in the file is as follows:
-
-        ```
-        train2017/0000001.jpg 0,259,401,459,7 35,28,324,201,2 0,30,59,80,2
-        ```
-
-        Each row is an image annotation which split by space, the first column is a relative path of image, the others are box and class infomations of the format [xmin,ymin,xmax,ymax,class]. We read image from an image path joined by the `IMAGE_DIR`(dataset directory) and the relative path in `ANNO_PATH`(the TXT file path), `IMAGE_DIR` and `ANNO_PATH` are setting in `config.py`.

+# [WarpCTC Description](#contents)
 
-## Requirements
+This is an example of training WarpCTC with self-generated captcha image dataset in MindSpore.
 
-- Install [MindSpore](https://www.mindspore.cn/install/en).
+# [Model Architecture](#content)
 
-- Generate captcha images.
+WarpCTC is a two-layer stacked LSTM appending with one-layer FC neural network. See src/warpctc.py for details.
 
-> The [captcha](https://github.com/lepture/captcha) library can be used to generate captcha images. You can generate the train and test dataset by yourself or just run the script `scripts/run_process_data.sh`. By default, the shell script will generate 10000 test images and 50000 train images separately.
-> ```
-> $ cd scripts
-> $ sh run_process_data.sh
-> 
-> # after execution, you will find the dataset like the follows:
-> .  
-> └─warpctc
->   └─data
->     ├─ train  # train dataset
->     └─ test   # evaluate dataset
->   ...
+# [Dataset](#content)
+
+The dataset is self-generated using a third-party library called [captcha](https://github.com/lepture/captcha), which can randomly generate digits from 0 to 9 in image. In this network, we set the length of digits varying from 1 to 4.
+
+# [Environment Requirements](#contents)
+
+- Hardware（Ascend/GPU）
+  - Prepare hardware environment with Ascend or GPU processor. If you want to try Ascend, please send the [application form](https://obs-9be7.obs.cn-east-2.myhuaweicloud.com/file/other/Ascend%20Model%20Zoo%E4%BD%93%E9%AA%8C%E8%B5%84%E6%BA%90%E7%94%B3%E8%AF%B7%E8%A1%A8.docx) to ascend@huawei.com.

-## Structure
+# [Quick Start](#contents)
+
+- Generate dataset.
+
+    Run the script `scripts/run_process_data.sh` to generate a dataset. By default, the shell script will generate 10000 test images and 50000 train images separately.
+ 
+    ```
+     $ cd scripts
+     $ sh run_process_data.sh
+     
+     # after execution, you will find the dataset like the follows:
+     .  
+     └─warpctc
+       └─data
+         ├─ train  # train dataset
+         └─ test   # evaluate dataset
+    ```
+
+- After the dataset is prepared, you may start running the training or the evaluation scripts as follows:
+
+    - Running on Ascend
+    ```
+    # distribute training example in Ascend
+    $ bash run_distribute_train.sh rank_table.json ../data/train
+  
+    # evaluation example in Ascend
+    $ bash run_eval.sh ../data/test warpctc-30-97.ckpt Ascend
+    
+    # standalone training example in Ascend
+    $ bash run_standalone_train.sh ../data/train Ascend
+    ```
+    For distributed training, a hccl configuration file with JSON format needs to be created in advance.
+
+    Please follow the instructions in the link below:
+
+    https://gitee.com/mindspore/mindspore/tree/master/model_zoo/utils/hccl_tools.
+    
+    - Running on GPU
+    
+    ```
+    # distribute training example in GPU
+    $ bash run_distribute_train_for_gpu.sh 8 ../data/train
+    
+    # standalone training example in GPU
+    $ bash run_standalone_train.sh ../data/train GPU
+  
+    # evaluation example in GPU
+    $ bash run_eval.sh ../data/test warpctc-30-97.ckpt GPU
