🧩 U-Net: Pixel-Perfect Image Segmentation

The simulation visualises image data flowing down through U-Net's contracting encoder and back up through its expanding decoder, showing the skip connections carrying detailed feature maps across the U in 3D.

🔬 What It Demonstrates

The simulation visualises image data flowing down through U-Net's contracting encoder and back up through its expanding decoder, showing the skip connections carrying detailed feature maps across the U in 3D.

🎮 How to Use

Pick a sample input image and press play to animate the forward pass layer by layer, or drag the speed slider and scrub manually to inspect how resolution and feature depth change at each stage.

💡 Did You Know?

The original 2015 U-Net paper won the ISBI cell tracking challenge by a large margin using only about 30 annotated training images, an astonishingly small dataset by deep learning standards.
