FaceDetect-IR Model Card

Model Overview

The model described in this card detects one or more faces in the given image / video. Compared to the PeopleNet model, this model gives better results detecting large faces, such as faces in webcam images.

Model Architecture

The model is based on NVIDIA DetectNet_v2 detector with ResNet18 as a feature extractor. This architecture, also known as GridBox object detection, uses bounding-box regression on a uniform grid on the input image. Gridbox system divides an input image into a grid which predicts four normalized bounding-box parameters (xc, yc, w, h) and confidence value per output class.

The raw normalized bounding-box and confidence detections needs to be post-processed by a clustering algorithm such as DBSCAN or NMS to produce final bounding-box coordinates and category labels.

Training

This model was trained using the DetectNet_v2 entrypoint in TAO. The training algorithm optimizes the network to minimize the localization and confidence loss for the objects. The training is carried out in two phases. In the first phase, the network is trained with regularization to facilitate pruning. Following the first phase, we prune the network removing channels whose kernel norms are below the pruning threshold. In the second phase the pruned network is retrained. Regularization is not included during the second phase.

Training Data

FaceDetectIR v1.0 model was trained on a proprietary dataset with more than 846K faces. The training dataset consists of images taken from cameras mounted at varied heights and angles, cameras of varied field-of view (FOV) and occlusions. While most training images are IR (gray) images, some color (RGB) images are added as seeded content to improve accuracy of the models.

Training Data Ground-truth Labeling Guidelines

The training dataset is created by labeling ground-truth bounding-boxes and categories by human labellers. Following guidelines were used while labelling the training data for NVIDIA FaceDetectIR model.

FaceDetectIR project labelling guidelines

Face bounding boxes should be as tight as possible.
Label each face bounding box with an occlusion level ranging from 0 to 9. 0 means the face is fully visible and 9 means the face is 90% or more occluded. For training, only faces with occlusion level 0-5 are considered.
The datasets consist of webcam images so truncation is rarely seen. If faces are at the edge of the frame with visibility less than 60% due to truncation, this image is dropped from the dataset.

Performance

Evaluation Data

The inference performance of FaceIR v1.0 model was measured against 16559 proprietary images across a variety of environments, occlusion conditions, camera heights and camera angles.

Methodology and KPI

The true positives, false positives, false negatives are 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 precision, recall and accuracy.

The key performance indicators (KPI) are calculated for IR images only. There are no color images in our evaluation set.

Real-time Inference Performance

The inference is run on the provided pruned model at INT8 precision. The inference performance is run using trtexec on Jetson Nano, AGX Xavier, Xavier NX and NVIDIA T4 GPU. On the Jetson Nano FP16 inference is run. The Jetson devices are running at Max-N configuration for maximum GPU frequency. The performance shown here is the inference only performance. The end-to-end performance with streaming video data might slightly vary depending on other bottlenecks in the hardware and software.

How to use this model

This model needs to be used with NVIDIA Hardware and Software. For Hardware, the model can run on any NVIDIA GPU including NVIDIA Jetson devices. This model can only be used with Train Adapt Optimize (TAO) Toolkit, DeepStream SDK or TensorRT.

The primary use case for this model is to detect faces from an IR (infrared) camera. The model can be used to detect faces from photos and videos by using appropriate video or image decoding and pre-processing. As a secondary use case the model can also be used to detect faces in RGB (color) images. However, this is not the main intended use for this model.

There are two flavors of the model:

unpruned
pruned

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

The pruned model is intended for efficient deployment on the edge using DeepStream SDK or TensorRT. This model accepts 384x240x3 dimension input tensors and outputs 24x15x4 bbox coordinate tensor and 24x15x1 class confidence tensor. DeepStream provides a toolkit to create efficient video analytic pipelines to capture, decode, and pre-process the data before running inference. DeepStream will then post-process the output bbox coordinate tensor and class confidence tensors with NMS or DBScan clustering algorithm to create appropriate bounding boxes. The sample application and config file to run this model are provided in DeepStream SDK.

The unpruned and pruned models are encrypted and will only operate with the following key:

Model load key: tlt_encode

Please make sure to use this as the key for all TAO commands that require a model load key.

Input

Gray Image whose values in RGB channels are the same. 384 X 240 X 3 (W x H x C)\nChannel Ordering of the Input: NCHW, where N = Batch Size, C = number of channels (3), H = Height of images (240), W = Width of the images (384)\nInput scale: 1/255.0\nMean subtraction: None

Output

Category labels (faces) and bounding-box coordinates for each detected face in the input image.

By downloading the unpruned or pruned version of the model, you accept the terms and conditions of these [licenses](https://www.nvidia.com/en-us/data-center/products/nvidia-ai-enterprise/eula/).\n\n## Ethical Considerations \n\nNVIDIA FaceIR model detects faces. However, no additional information such as race, gender, and skin type about the faces is inferred.\n\nNVIDIA’s platforms and application frameworks enable developers to build a wide array of AI applications. Consider potential algorithmic bias when choosing or creating the models being deployed. Work with the model’s developer to ensure that it meets the requirements for the relevant industry and use case; that the necessary instruction and documentation are provided to understand error rates, confidence intervals, and results; and that the model is being used under the conditions and in the manner intended.","displayName","FaceDetectIR",["D",1731434401235],"publisher","NVIDIA","latestVersion","versions","collectionCounts","imageUrl","/api/image/nvidia/tao/models/facedetectir","rawImageUrl","https://raw.githubusercontent.com/kbojo/images/master/Nvidia-Centric-TAO.png","canGuestDownload","latestVersionSizeInBytes",9532530,"licenseTerms","isMultinodeEnabled","isMultiArchitecture","bias","explainability","privacy","safetyAndSecurity","featureLabels",[316],"displayLabels",[257,258,259,260,261,262,263,264,265,266,267,268,269,270],"policyLabels",[],"systemLabels",[],"products",[],"hasNimMetadata",{"_224":314,"_272":314,"_273":315,"_275":276},{"_224":311,"_272":312,"_273":313,"_275":276},{"_224":309,"_272":309,"_273":310,"_275":276},{"_224":306,"_272":307,"_273":308,"_275":276},{"_224":304,"_272":304,"_273":305,"_275":276},{"_224":300,"_272":301,"_273":302,"_275":276},{"_224":298,"_272":298,"_273":299,"_275":276},{"_224":294,"_272":295,"_273":296,"_275":276},{"_224":290,"_272":291,"_273":292,"_275":276},{"_224":288,"_272":288,"_273":289,"_275":276},{"_224":285,"_272":286,"_273":287,"_275":276},{"_224":281,"_272":282,"_273":283,"_275":276},{"_224":279,"_272":279,"_273":280,"_275":276},{"_224":271,"_272":271,"_273":274,"_275":276},"TAO Toolkit","value","filter",{"_277":278,"_272":271},"category","label","field","framework","Smart Infrastructure",{"_277":276,"_272":279},"Smart Cities / Spaces","indus_smart_cities_spaces",{"_277":284,"_272":282},"industry","Retail","indus_retail",{"_277":284,"_272":286},"Public Safety",{"_277":276,"_272":288},"Object Detection","uscs_object_detection",{"_277":293,"_272":291},"application","NVIDIA AI","soln_nvidia_ai",{"_277":297,"_272":295},"technology","NSPECT-1DBQ-GZ4A",{"_277":276,"_272":298},"Metropolis","pltfm_metropolis",{"_277":303,"_272":301},"platform","IR",{"_277":276,"_272":304},"Healthcare","indus_healthcare",{"_277":284,"_272":307},"DetectNet_v2",{"_277":276,"_272":309},"DeepStream","pltfm_deepstream",{"_277":303,"_272":312},"CV",{"_277":276,"_272":314},{"_224":317,"_272":317,"_273":318,"_275":319},"NVIDIA AI Enterprise Supported",{"_277":276,"_272":317},"feature",{"_118":1492,"_120":1493},"ngcApps",[1445],"csaApiBaseUrl","https://www.nvidia.com/ai-agents/csa-agent/dcsm","datadogRum",{"_1426":1427,"_1428":1429,"_1430":1431,"_1432":1433,"_1434":331,"_149":355,"_1435":1436,"_1437":56,"_1438":97,"_1439":97,"_1440":1441,"_1442":97,"_1443":1444},"amplitude",{"_1423":1424,"_1026":-7,"_1425":32},"disableJs","environment","prod","featureFlagsBlob","JTdCJTIydGVzdEZsYWclMjIlM0FmYWxzZSUyQyUyMnNob3dTZWFyY2hMYWJlbFNldEZpbHRlcnMlMjIlM0FmYWxzZSUyQyUyMmNoaW5hTmltRGlzdHJpYnV0b3JzUmVkZXNpZ24lMjIlM0F0cnVlJTJDJTIyZW5hYmxlQ3NhV2lkZ2V0JTIyJTNBZmFsc2UlMkMlMjJlbmFibGVQcm9kdWN0R3JvdXBpbmdCeVN1YnNjcmlwdGlvbiUyMiUzQWZhbHNlJTJDJTIyY29udGFpbmVyU2Nhbm5pbmdSZWRlc2lnbk0xJTIyJTNBdHJ1ZSU3RA==","featureFlagsGuarded","isDevLikeEnv","isPlaywright","isMobileDevice","categorizedOrgs",{"_1417":1418,"_1419":1420,"_1421":1422},"currentOrgContext","currentContextRoles",[],"enterpriseOrgs",[],"locale","en","ngcApiOrigin","ngcHelmOrigin","origin","https://catalog.ngc.nvidia.com","usesMocks","theme","year",2026,"1.7.3","defaultSearchSuggestions",{"_1301":179,"_1302":1303,"_1304":1305,"_1306":1307},"announcements",[],"consentState",{"_392":1291,"_1292":97,"_1293":32,"_1294":32,"_1295":1296},"consentConfig",{"_374":375,"_376":377,"_378":379,"_380":381,"_382":383,"_384":385,"_386":387,"_388":389,"_390":391,"_392":393},"showContactAdmin",1783933066842,[],[],[369,370,371,372,373],{"_46":60,"_48":71,"_50":113,"_52":-5,"_54":-5,"_55":56},{"_46":60,"_48":69,"_50":113,"_52":-5,"_54":-5,"_55":56},{"_46":60,"_48":61,"_50":113,"_52":-5,"_54":-5,"_55":56},{"_46":57,"_48":58,"_50":113,"_52":-5,"_54":-5,"_55":56},{"_46":47,"_48":49,"_50":113,"_52":-5,"_54":-5,"_55":56},"mainInfoText","We and our third-party partners (including social media, advertising, and analytics partners) use cookies and other tracking technologies to collect, store, monitor, and process certain information about you when you visit our website.
