# Canny Edge Detection — Step by Step

Upload any image to see all seven stages of the Canny edge detector — grayscale,
Gaussian blur, Sobel gradients (magnitude + direction), non-maximum suppression,
double threshold, and hysteresis.

This Space runs the **NumPy reference implementation**. The full project also
includes a **custom CUDA pipeline (6 kernels) that runs 5–11× faster** than
NumPy on the same workloads, validated to a pixel-for-pixel match (IoU = 1.0000).
