It does not exhibit the artifacts that Noise Ninja and Noiseware does. Here, BNR is conservative in its noise reduction and perhaps overly so. In situations such as this, Denoise can create spurious "worm-like" patterns. When noise is confused with detail, artifacts usually result. One problem with noise reduction is that the algorithm cannot always figure out what is detail and what is noise. Unfortunately, it will also recover image details that do not really exist. It does an excellent job at recovering image detail (in my opinion, it is the best at it). Unfortunately in this situation, these aggressive defaults are inappropriate.ĭenoise tends to give very different results. The aggressive sharpening also counteracts the blurriness that can occur when noise in removed. In many situations, this can be appropriate since many objects do not look right if they lack enough texture. It is also applying more aggressive sharpening. Unlike Noiseware, Noise Ninja is retaining more of the original image's luma information. Like Noiseware, Noise Ninja also has problems with the same artifacts. The choice of RAW processing will affect noise reduction results. ACR tends to be aggressive about recovering detail and may leave behind debayering/demoasicing artifacts which noise reduction software can exaggerate. Note: Adobe Camera RAW was used to process the image. Setting the noise level higher in Noiseware would remove these artifacts (at the expense of image detail). However, the red arrows point out erroneous artifacts left behind by the algorithm. Noiseware does a good job of removing noise. There was no manual tweaking of noise reduction parameters/settings. For all the others, automatic profiling was used. There is extreme noise in this random image of a newspaper sitting on a mall bench.įor Denoise, the best-looking preset was chosen. Test Image #1Īll images are zoomed in 200%, nearest neighbour resizing. Please keep that in mind since all the examples in this article are based on automatic settings. There are some cases where the profiling is way off and manual intervention is needed to bring out the best results. This can cause the profiling algorithm to get the characteristics of the remaining noise wrong.įor this and various other reasons, automatic profiling does not always work. Automatic profiling can miss in such a situation, and you should manually tweak the noise reduction settings instead.Īnother instance where automatic profiling tends to work poorly is if the camera applies its own noise reduction when recording to JPEG file formats. This is not the case if there are no smooth areas in the picture to begin with. the area is completely smooth) and only noise. Of course, you should try all the demos for the products yourself and make up your own mind! A little secret: automatic profiling does not always work!įor automatic profiling to work, the source image must have an area where there is no detail (i.e. With that being said, I will try to give a fair two-sided view on the noise reduction products on the market. Please note that I may be extremely biased as my software competes against these other excellent noise removal tools!!! The purpose of this article is to compare the pros and cons of Boundary Noise Reduction (BNR) compared to what I consider the leading competing products: Comparison of noise reduction algorithms: Boundary Noise Reduction, Noise Ninja, Noiseware, DenoiseĪ two-sided but extremely biased comparison of noise reduction software
