Real-time Edge-Aware Image Processing with the Bilateral Grid (SIGGRAPH 2007)
Method
- Create a low-resolution 3D grid with axis (x, y, intensity).
- For an 8MP image, they claim a \(70 \times 70 \times 10\) grid is sufficient.
- This is called a bilateral grid.
- Place pixels for your 2D image into bins within the bilateral grid based on x, y position and intensity.
- When performing image effects, only change pixels within slices of the grid: pixels within a certain intensity.
