Part 4: Practical Implementation – Running the Model

You do not need a deep learning researcher to use this model. Here is a Python implementation using onnxruntime and opencv.

1. TensorRT Conversion (NVIDIA GPUs)

Convert the ONNX to TensorRT for 0.5ms inference latency.

trtexec --onnx=w600k-r50.onnx --saveEngine=w600k-r50.engine --fp16

How to inspect the ONNX model (Python)

import onnx
model = onnx.load("w600k-r50.onnx")
print(model.graph.input)
print(model.graph.output)
for vi in model.graph.value_info[:10]:
    print(vi)

Or use onnxruntime to run a shape/profile pass:

import numpy as np
import onnxruntime as ort
sess = ort.InferenceSession("w600k-r50.onnx")
print([i.name + " " + str(i.shape) for i in sess.get_inputs()])
print([o.name + " " + str(o.shape) for o in sess.get_outputs()])
# dummy inference
N, C, H, W = 1, 3, 224, 224
dummy = np.random.rand(N, C, H, W).astype(np.float32)
out = sess.run(None, sess.get_inputs()[0].name: dummy)
print(type(out), [o.shape for o in out])

Option 3: Short Description (Readme/Snippet)

File: w600k-r50.onnx Type: Face Recognition Model

This file is an ONNX export of a ResNet-50 model trained on 600,000 identities (w600k). It is optimized for generating high-quality face embeddings. The model accepts a pre-processed face crop and outputs a dense vector suitable for cosine similarity matching. It is recommended for production environments requiring a balance between inference speed and recognition accuracy.

1. The Architecture: R50 (ResNet-50)

The "R50" stands for ResNet-50. ResNet (Residual Network) was a breakthrough architecture introduced by Microsoft Research in 2015. Before ResNet, training very deep neural networks was difficult due to the "vanishing gradient" problem.

  • Why 50 layers? ResNet-50 has 50 layers deep (48 convolutional layers + 1 max pooling + 1 average pooling). This is the "sweet spot." Models like ResNet-18 are too shallow for high-accuracy face embeddings, while ResNet-101 or 152 are too slow for real-time inference.
  • The "Residual Block" Magic: ResNet-50 uses skip connections (identity shortcuts) that allow gradients to flow directly through the network. This enables the model to learn subtle facial features like the distance between eyes or the curve of the jawbone without overfitting.

Normalization Parameters

The model expects specific preprocessing:

  • Mean: [0.5, 0.5, 0.5]
  • Standard Deviation: [0.5, 0.5, 0.5]
  • Formula: input = (pixel / 255.0 - mean) / std

Expected I/O details (assumptions + checks to run)

  1. Input tensor:
    • dtype: float32
    • shape: [N, 3, H, W] (N = batch size)
    • pixel range: either [0, 1] or [0, 255] — most ResNet ONNX models expect [0,1] after mean/std normalization.
    • normalization: common ImageNet normalization: mean = [0.485, 0.456, 0.406], std = [0.229, 0.224, 0.225]. Some models use BGR order and mean [103.53,116.28,123.675] with scale 1.0.
  2. Output tensor:
    • name: something like "output", "features", or "fc1"
    • shape: [N, D] where D might be 2048 (pooled features) or smaller if a projection head applied.
  3. Optional additional outputs:
    • logits/class scores if trained for classification
    • intermediate tensors if exported with names
