Most models use external data format (
.onnx+.onnx.data). Both files must be in the same directory for loading.

| Model | Normalization | Notes |
|---|---|---|
| DBCNN, HyperIQA, TReS | ImageNet: mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225] | Standard ImageNet |
| MANIQA | Inception: mean=[0.5, 0.5, 0.5], std=[0.5, 0.5, 0.5] | |
| MUSIQ | [-1, 1]: (x - 0.5) / 0.5 | Equivalent to Inception |
| CLIPIQA | CLIP: mean=[0.48145466, 0.4578275, 0.40821073], std=[0.26862954, 0.26130258, 0.27577711] | |
| LIQE | CLIP: same as CLIPIQA | Two-stage: CLIP encoder → LIQE scorer |
For multi-crop inference (recommended for HyperIQA, MANIQA, TReS), extract multiple 224×224 crops from the full-resolution image and average the scores.
LIQE requires a two-stage pipeline:
import json
import onnxruntime as ort
import numpy as np
# Load both models and text features
clip_sess = ort.InferenceSession("clip_model.onnx")
liqe_sess = ort.InferenceSession("liqe_model.onnx")
with open("text_features.json") as f:
text_features = np.array(json.load(f), dtype=np.float32)
# Step 1: Extract image features with CLIP
img_input = preprocess_clip(image) # (1, 3, 224, 224)
img_features = clip_sess.run(None, {"input": img_input})[0]
# Step 2: Score with LIQE
score = liqe_sess.run(None, {
"image_features": img_features,
"text_features": text_features
})[0]
