Noise Reduction in Rendering

Noise reduction in rendering is a process used in computer graphics to minimize unwanted visual artifacts, known as noise, that can occur during the rendering of an image. Noise can manifest as random, grainy patterns that degrade the overall quality of the final image. By reducing noise, the final image appears smoother and more visually appealing.

There are several techniques used for noise reduction in rendering, including:

  1. Sampling Techniques: Increasing the number of samples taken per pixel can help reduce noise by averaging out inconsistencies in the image.

  2. Filtering Algorithms: Applying filters to the image can help smooth out noise while preserving important details.

  3. Adaptive Sampling: Focusing sampling efforts on areas of the image that are most likely to contain noise can help reduce overall noise levels.

  4. Overall, noise reduction in rendering is an important step in the rendering process to ensure that the final image is of high quality and visually appealing.
