Скачать или смотреть I made my GPU edge faster with this one simple trick.

Bilinear edge detection is a relatively obscure topic. However, developers such as Timothy Lottes, Jorge Jimenez, and Dmitry Andreev, authors of FXAA, SMAA, and DLAA, respectively, use bilinear interpolation for robust edge detection.

Key Takeaways
• The Sobel filter is a popular edge detection algorithm
• We optimize the Sobel filter with bilinear interpolation
• We optimize by sampling between pixels, not on the pixel
• We have the same results because the center pixels cancel out
