Prepare noisy-clean pairs
Create a dataset of clean images and generate corrupted versions with realistic noise (Gaussian, salt-and-pepper, compression artefacts), then split into train/val/test.
Denoise images with an autoencoder. Assess reconstruction quality.
An image denoising autoencoder learns to reconstruct clean images from corrupted inputs by minimising a reconstruction loss. Key considerations include how to add realistic noise, choose an encoder–decoder architecture, measure reconstruction quality (PSNR, SSIM, MSE), and validate generalisation to unseen noise patterns.

A proposed application: a preprocessing service for scanned documents or low-light photos to improve downstream OCR or visual inspection. Any deployment should keep a human reviewer in the loop for critical outputs.
Create a dataset of clean images and generate corrupted versions with realistic noise (Gaussian, salt-and-pepper, compression artefacts), then split into train/val/test.
Define a small convolutional encoder–decoder in PyTorch or TensorFlow and train it with an L2 or SSIM-based loss on noisy-to-clean image pairs.
Report PSNR and SSIM on the test set, inspect qualitative examples, and check failure modes such as detail loss and hallucinated textures.
Export a lightweight inference model, add runtime input validation, and monitor reconstruction metrics and input-noise distribution drift.
The supplied starter loads scikit-learn's digits dataset, splits it, trains a RandomForestClassifier, prints a classification report, and shows a confusion matrix. It does not implement an autoencoder, does not corrupt images with noise, and performs classification rather than image 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 contains no autoencoder or neural-network training, it performs digit classification with RandomForest, and it never creates or removes noise — so it does not implement image denoising or reconstruction.
Proposed extension: replace the classifier with a small convolutional autoencoder trained to map noisy images to their clean counterparts, and evaluate with PSNR/SSIM and visual examples.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
