Denoise
The “Value Domain” slider refers to the range that the software uses to analyze the neighboring pixels to an
area suspected of noise. The higher this is, the longer the image will take to process, as it averages a larger
area per pixel. Too large may cause strange artifacting, so it’s best to keep it near the mid point of the slider
and adjust in small increments as needed.
The “Space Domain” slider refers to how strong the denoising effect will be. The higher this value, the more
aggressively the software will detect rogue pixels as noise. Best kept to the lower end of the spectrum as too
high, and many items in your image that are as pictured correctly may be averaged out, losing out on image
quality.
Non Local Means - This method uses a weighted average of pixels over a given area to extrapolate what is
noise and what is not over a separate area not adjacent to the search area. This allows a user to denoise more
accurately than only denoising over a local area via the adjacent pixels, and provides greater flexibility in repro -
ducing accurate to object images.
The “Strength” slider refers to the aggressiveness of the software’s noise removal. The higher this is, the more
noise will be removed, however too high and detail will be lost beyond jut noise.
The “Template Window” slider refers to the template block size, and is used to calculate the weight at which
the pixels will be averaged when a noisy pixel is detected based on the template area.
The “Search Window” slider is used to calculate how large of an area will be averaged when a noisy pixel is
found in the target area for denoising.
When finished adjusting the sliders, press the “OK” button to engage the software’s denoising process. The
resulting image will be displayed once complete.
