Technical Architecture
ESRGAN Neural Network
The Enhanced Super-Resolution Generative Adversarial Network architecture is optimized for edge-preservation. It uses residual blocks to focus on high-frequency details that are lost in traditional compression.
Hardware Accelerated Tensors
We use TensorFlow.js with the WebGL backend, allowing the upscaling math to run on your GPU. This provides a 10-20x speedup compared to standard CPU processing.
