MaskRCNN Description
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
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.
This network uses MobileNetV1 as the backbone of the maskrcnn_mobilenetv1 network.

Dataset
Note that you can run the scripts based on the dataset mentioned in original paper or widely used in relevant domain/network architecture. In the following sections, we will introduce how to run the scripts using the related dataset below.
-
COCO2017 is a popular dataset with bounding-box and pixel-level stuff annotations. These annotations can be used for scene understanding tasks like semantic segmentation, object detection and image captioning. There are 118K/5K images for train/val.
-
Dataset size: 19G
- Train: 18G, 118000 images
- Val: 1G, 5000 images
- Annotations: 241M, instances, captions, person_keypoints, etc.
-
Data format: image and json files
- Note: Data will be processed in dataset.py
Environment Requirements
-
Hardware（Ascend/CPU）
- Prepare hardware environment with Ascend or CPU processor or GPU.
-
Framework
-
For more information, please check the resources below:
-
third-party libraries
pip install Cython
pip install pycocotools
pip install mmcv=0.2.14
Quick Start
-
Download the dataset COCO2017.
-
Change the COCO_ROOT and other settings you need in
default_config.yaml. The directory structure should look like the follows:. └─cocodataset ├─annotations ├─instance_train2017.json └─instance_val2017.json ├─val2017 └─train2017If 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 0,30,59,80,2Each 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 inANNO_PATH(the TXT file path), which can be set indefault_config.yaml. -
Execute train script.
After dataset preparation, you can start training as follows:On Ascend: # distributed training bash run_distribute_train.sh [RANK_TABLE_FILE] [DATA_PATH] [PRETRAINED_CKPT(optional)] # example: bash run_distribute_train.sh ~/hccl_8p.json /home/DataSet/cocodataset/ # standalone training bash run_standalone_train.sh [DATA_PATH] [PRETRAINED_CKPT(optional)] # example: bash run_standalone_train.sh /home/DataSet/cocodataset/ On CPU: # standalone training bash run_standalone_train_cpu.sh [PRETRAINED_PATH](optional) On GPU: # distributed training bash run_distribute_train_gpu.sh [DATA_PATH] [PRETRAINED_PATH] (optional)Note:
- 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.
- For distributed training, a hccl configuration file with JSON format needs to be created in advance.
- For large models like maskrcnn_mobilenetv1, it's better to export an external environment variable
export HCCL_CONNECT_TIMEOUT=600to extend hccl connection checking time from the default 120 seconds to 600 seconds. Otherwise, the connection could be timeout since compiling time increases with the growth of model size.
-
Execute eval script.
After training, you can start evaluation as follows:
# Evaluation on Ascend bash run_eval.sh [ANN_FILE] [CHECKPOINT_PATH] [DATA_PATH] [DEVICE_TARGET] # example: bash run_eval.sh /home/DataSet/cocodataset/annotations/instances_val2017.json /home/model/maskrcnn_mobilenetv1/ckpt/mask_rcnn-5_7393.ckpt /home/DataSet/cocodataset/ "Ascend" # Evaluation on CPU bash run_eval_cpu.sh [ANN_FILE] [CHECKPOINT_PATH] # Evaluation on GPU bash run_eval.sh [ANN_FILE] [CHECKPOINT_PATH] [DATA_PATH] [DEVICE_TARGET]Note:
- VALIDATION_JSON_FILE is a label json file for evaluation.
-
Execute inference script.
After training, you can start inference as follows:
# inference bash run_infer_310.sh [MODEL_PATH] [DATA_PATH] [ANN_FILE_PATH]Note:
- MODEL_PATH is a model file, exported by export script file.
- ANN_FILE_PATH is a annotation file for inference.
-

As for PRETRAINED_MODEL, if not set, the model will be trained from the very beginning. Ready-made pretrained_models are not available now. Stay tuned.
This is processor cores binding operation regarding thedevice_numand total processor numbers. If you are not expect to do it, remove the operationstasksetinscripts/run_distribute_train.sh
- Run
run_distribute_train_gpu.shfor distributed training of Mask model on GPU.

Training Result
Training result will be stored in the example path, whose folder name begins with "train" or "train_parallel". You can find checkpoint file together with result like the following in loss_rankid.log.

EXPORT_FORMAT should be in ["AIR", "MINDIR"]
Inference Process
Before inference, please refer to Environment Variable Setting Guide to set environment variables.
Inference
Before performing inference, we need to export model first. Air model can only be exported in Ascend 910 environment, mindir model can be exported in any environment.
Current batch_ Size can only be set to 1. The inference process needs about 600G hard disk space to save the reasoning results.

Inference result
Inference result is saved in current path, you can find result like this in acc.log file.
