Collect multiview data
Capture many overlapping images with known intrinsics or run structure-from-motion (COLMAP) to estimate camera poses; avoid blurred or moving frames.
Reconstruct 3D scenes with NeRF. Assess view synthesis quality.
Neural radiance fields (NeRF) learn a continuous 3D scene representation from many calibrated 2D images so you can synthesise novel views. Success depends on camera calibration, diverse viewpoints, sufficient overlap, and handling reflective or dynamic surfaces. Common failure modes include floaters (spurious geometry), view-dependent artefacts, and overfitting to few viewpoints.

A proposed application: create navigable 3D previews for small-object e-commerce or cultural-heritage digitisation, with a human in the loop to approve reconstructions before publishing. This extension is not implemented in the supplied starter code.
Capture many overlapping images with known intrinsics or run structure-from-motion (COLMAP) to estimate camera poses; avoid blurred or moving frames.
Undistort images, crop consistently and split data into training and held-out cameras for quantitative evaluation of novel-view synthesis.
Implement or reuse a NeRF training loop (positional encoding, volumetric rendering) and monitor PSNR, SSIM and training loss on held-out views.
Report PSNR/SSIM on held-out views, visualise novel-view renders and inspect geometry (depth maps) for floaters and missing surfaces.
The supplied starter does not implement NeRF. It loads scikit-learn's digits dataset, trains a RandomForestClassifier on flattened digit images, prints a classification report and plots a confusion matrix — a supervised image-classification baseline unrelated to multi-view 3D reconstruction.
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(PROJECT_NAME)
print(classification_report(y_test, predictions))
The starter uses the sklearn digits dataset and a RandomForest classifier for 2D digit recognition. It contains no NeRF model, no multiview geometry, no camera-pose handling and no volumetric rendering, so it cannot train or evaluate a radiance field or produce novel-view renders.
A proposed extension: build a small NeRF pipeline that consumes COLMAP camera poses and multiview images, trains a compact radiance-field model, and provides an interface to render held-out viewpoints for reviewer approval.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
