Fine-tuning Data

This model is fine-tuned on about 600 real proprietary images from 6 different real environments. In each environment, only 1 image per item is collected.

The fine tuning data are captured under random camera heights and field of views. All fine tuning data were collected indoor, having retail items placed at the checkout counter, shelf, baskets, and conveyor belt. The camera is typically set up at approximately 10 feet height, 45-degree angle off the vertical axis and has close field-of-view. This content was chosen to decrease the simulation-to-reality gap of the model trained on synthetic data, and to improve the accuracy and the robustness of the model. The logos on retail items were smudged.

Fine-tuning Data Ground-truth Labeling Guidelines

The fine tuning data are created by labeling ground-truth bounding-boxes and categories by human-labelers. The following guidelines were used while labeling the training data for NVIDIA Retail Detection models. If you are looking to transfer-learn or to fine-tune the models to adapt to your target environment and classes, please follow the guidelines below for better model accuracy.

All objects that fall under the definition of retail items and are larger than the smallest bounding-box limit for the corresponding class (height >= 10px OR width >= 10px) are labeled with the appropriate class label.
Occlusion: For partially occluded objects that are visible approximately 60% or are marked as visible objects with a bounding box around the visible part of the object. These objects are marked as partially occluded. Objects under 60% visibility are not annotated.
Truncation: An object, at the edge of the frame, which is 60% or more visible is marked with the truncation flag.
Each frame is not required to have an object.

Evaluation Dataset:

Data Collection Method by dataset:

Automatic/Sensors

Labeling Method by dataset:

Human

Properties:
\n15,000 proprietary real-world images of objects found in retail settings.

Methodology and KPI

AP50 is calculated using intersection-over-union (IOU) criterion greater than 0.5. The KPI for the evaluation data are reported in the table below. Model is evaluated based on AP50 and AR0.5:0.95. Both AR and AP numbers are based on 100 maximum detections each image. Please note that “unseen items” measurements are irrelevant to the 100-class detection model.

Ethical Considerations:

NVIDIA Retail Object Detection model detects retail items. However, no additional information such as people and other distractors in the background are inferred. Training and evaluation dataset mostly consists of North American content. An ideal training and evaluation dataset would additionally include content from other geographies.

NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications. When downloaded or used in accordance with our terms of service, developers should work with their internal model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse. For more detailed information on ethical considerations for this model, please see the Model Card++ Promise and the Explainability, Bias, Safety & Security, and Privacy Subcards.

\n* Automatic/Sensors
\n\n**Labeling Method by dataset:**
\n* Human
\n\n**Properties:**
\n320,000 proprietary synthetic images of objects found in retail settings randomizing several simulation domains including:\n- light types, light intensities\n- object sizes, orientations, and locations\n- camera locations\n- background textures\n- flying distractors\n\nThe background textures are real images sampled from:\n\n- Proprietary real images \n- images taken from a retail checkout counter \n- HDRI texture maps create by NVIDIA Omniverse\n\nEach synthetic image contains 1 target retail item. This dataset is set up to simulate the diverse environments in the real world and to have the detector learn to extract retail items from noisy backgrounds. The logos on retail items were smudged.\n\n

\n\n| dataset | total #images | train #images | val #images |\n| ------------------------------------------------- | ------------- | ------------- | ----------- |\n| Synthetic data | 1,500,000 | 1,425,000 | 75,000 |\n| Real data - checkout counter 45 overhead | 107 | 85 | 23 |\n| Real data - shelf | 107 | 85 | 22 |\n| Real data - conveyor belt | 106 | 84 | 22 |\n| Real data - basket | 106 | 84 | 22 |\n| Real data - checkout counter barcode scanner view | 125 | 100 | 25 |\n| Real data - checkout counter overhead | 98 | 80 | 18 |\n\n#### Fine-tuning Data\n\nThis model is fine-tuned on about 600 real proprietary images from 6 different real environments. In each environment, only 1 image per item is collected. \n\nThe fine tuning data are captured under random camera heights and field of views. All fine tuning data were collected indoor, having retail items placed at the checkout counter, shelf, baskets, and conveyor belt. The camera is typically set up at approximately 10 feet height, 45-degree angle off the vertical axis and has close field-of-view. This content was chosen to decrease the simulation-to-reality gap of the model trained on synthetic data, and to improve the accuracy and the robustness of the model. The logos on retail items were smudged.\n\n

\n\n#### Fine-tuning Data Ground-truth Labeling Guidelines\n\nThe fine tuning data are created by labeling ground-truth bounding-boxes and categories by human-labelers. The following guidelines were used while labeling the training data for NVIDIA Retail Detection models. If you are looking to transfer-learn or to fine-tune the models to adapt to your target environment and classes, please follow the guidelines below for better model accuracy.\n\n1. All objects that fall under the definition of retail items and are larger than the smallest bounding-box limit for the corresponding class (height >= 10px OR width >= 10px) are labeled with the appropriate class label.\n2. Occlusion: For partially occluded objects that are visible approximately 60% or are marked as visible objects with a bounding box around the visible part of the object. These objects are marked as partially occluded. Objects under 60% visibility are not annotated.\n3. Truncation: An object, at the edge of the frame, which is 60% or more visible is marked with the truncation flag.\n4. Each frame is not required to have an object.\n\n## Evaluation Dataset:\n**Data Collection Method by dataset:**
