OCDNet Model Overview

Model Overview

The model described in this card is an optical characters detection network, which aims to detect text in images. Trainable and deployable OCDNet models are provided. These are trained on Uber-Text dataset and ICDAR2015 dataset respectively.

Terms of use

License to use these models is covered by the Model EULA. By downloading the unpruned or pruned version of the model, you accept the terms and conditions of these licenses.

Model Architecture

This model is based on a relatively sophisticated text detection network called DBNet. DBNet is a network architecture for real-time scene text detection with differentiable binarization. It aims to solve the problem of text localization and segmentation in natural images with complex backgrounds and various text shapes.

Training

The training algorithm inserts the binarization operation into the segmentation network and jointly optimizes it so that\nthe network can learn to separate foreground and background pixels more effectively. The binarization threshold is learned by minimizing the IoU loss between the predicted binary map and the ground truth binary map.

Training Data

The trainable models were trained on the Uber-Text dataset and ICDAR2015 dataset respectively. The Uber-Text dataset contains street-level images collected from car mounted sensors and truths annotated by a team of image analysts--including train_4Kx4K, train_1Kx1K, val_4Kx4K, val_1Kx1K, test_4Kx4K as the training datasets and test_1Kx1K as the validation dataset. The dataset was constructed with 107812 images for training and 10157 images for validation. The ICDAR2015 dataset contains 1000 training images and 500 test images. The deployable models were ONNX models that were exported using the trainable models.

Performance

Evaluation Data

Real-time Inference Performance

The inference uses FP16 precision. The input shape is <batch>x3x640x640. The inference performance runs against an OCDNet-deployable model with trtexec on AGX Orin, Orin NX, Orin Nano, NVIDIA L4, NVIDIA L4, and NVIDIA A100 GPUs. The Jetson devices run at Max-N configuration for maximum system performance. The data is for inference-only performance. The end-to-end performance with streaming video data might vary slightly depending on the application's use case.

How to Use This Model

This model needs to be used with NVIDIA Hardware and Software: The model can run on any NVIDIA GPU, including NVIDIA Jetson devices, with TAO Toolkit, DeepStream SDK or TensorRT.

The primary use case for this model is to detect text on images.

There are two types of models provided (both unpruned).

trainable
deployable

The trainable models are intended for training with the user's own dataset using TAO Toolkit. This can provide high-fidelity models that are adapted to the use case. A Jupyter notebook is available as a part of the TAO container and can be used to re-train.

The deployable models share the same structure as the trainable model, but in onnx format. The deployable models can be deployed using TensorRT, nvOCDR, and DeepStream.

Input

Images of C x H x W (H and W should be multiples of 32.)

Output

BBox or polygon coordinates for each detected text in the input image

For more information on the experiment spec file, refer to the [TAO Toolkit User Guide](https://docs.nvidia.com/tao/tao-toolkit/index.html).\n\nTo use trainable_resnet18_v1.0 model:\n```yaml\nmodel:\n load_pruned_graph: False\n pruned_graph_path: '/results/prune/pruned_0.1.pth'\n pretrained_model_path: '/data/ocdnet/ocdnet_deformable_resnet18.pth'\n backbone: deformable_resnet18\n```\nTo use trainable_ocdnet_vit_v1.0 model:\n```yaml\nmodel:\n load_pruned_graph: False\n pruned_graph_path: '/results/prune/pruned_0.1.pth'\n pretrained_model_path: '/data/ocdnet/ocdnet_fan_tiny_2x_icdar.pth'\n backbone: fan_tiny_8_p4_hybrid\n enlarge_feature_map_size: True\n activation_checkpoint: True\n```\n\n### Instructions to deploy the model with DeepStream\n\nTo create the entire end-to-end video analytic application, deploy this model with [DeepStream SDK](https://developer.nvidia.com/deepstream-sdk). DeepStream SDK is a streaming analytic toolkit to accelerate building AI-based video analytic applications. DeepStream supports direct integration of this model into the Deepstream sample app.\n\nTo deploy this model with [DeepStream](https://developer.nvidia.com/deepstream-sdk), follow [these instructions](https://docs.nvidia.com/tao/tao-toolkit/text/ds_tao/nvocdr_ds.html).\n\n## Limitations \n\n### Restricted Usage in Different Fields\n\nThe NVIDIA OCDNet trainable model is trained on Uber Text, ICDAR2015 and PCB text dataset, which contains street-view images only. To get better accuracy in a specific field, more data is usually required to fine tune the pre-trained model with TAO Toolkit.\n\n## Model versions:\n\n- **trainable_resnet18_v1.0** - Pre-trained models with deformable-resnet18 backbone, trained on Uber-Text dataset.\n- **trainable_resnet50_v1.0** - Pre-trained models with deformable-resnet50 backbone, trained on Uber-Text dataset.\n- **trainable_ocdnet_vit_v1.0** - Pre-trained models with fan-tiny backbone, trained on ICDAR2015 dataset.\n- **trainable_ocdnet_vit_v1.1** - Pre-trained models with fan-tiny backbone, trained on Uber-Text dataset.\n- **trainable_ocdnet_vit_v1.2** - Pre-trained models with fan-tiny backbone, trained on PCB dataset.\n- **trainable_ocdnet_vit_v1.3** - Pre-trained models with fan-tiny backbone, trained on ImageNet2012 dataset.\n- **trainable_ocdnet_vit_v1.4** - Pre-trained models with fan-tiny backbone, trained on ICDAR2015 dataset and model are pruned.\n- **deployable_v1.0** - Model deployable with deformable-resnet backbone.\n- **deployable_v2.0** - Model deployable with fan-tiny backbone, trained on ICDAR2015.\n- **deployable_v2.1** - Model deployable with fan-tiny backbone, trained on Uber-Text.\n- **deployable_v2.2** - Model deployable with fan-tiny backbone, trained on PCB dataset.\n- **deployable_v2.3** - Model deployable with fan-tiny backbone, trained on ICDAR2015 and model are pruned.\n\n## Reference\n\n### Citations \n\n- Liao M., Wan Z., Yao C., Chen K., Bai X.: Real-time Scene Text Detection with Differentiable Binarization (2020).\n- Dai, J., Qi, H., Xiong, Y., Li, Y., Zhang, G., Hu, H., and Wei, Y: Deformable convolutional networks.
