Noiseware Software Noise Reduction
Noiseware is a software program from Imagenomic. The program claims to take a different approach to noise reduction by using Artificial Intelligence techniques for noise reduction instead of simple median filters. The core of the system is an automatic profile system that attempts to analyze and recognize noise patterns for more effective noise detection. The program is adaptive and uses EXIF data and the results of its analysis to build a noise processing algorithm that becomes more effective as more images are processed. In automatic mode the program considers the image as a whole. Noiseware also features the option of a manual mode for manual noise profiling by specifying certain regions for noise reduction.
Noiseware is available as a standalone program, or as a plug-in for Adobe Photoshop or Elements. Current versions are available for the MAC or PC, with current PC versions working under Vista or XP. The cost is free for the Community Edition standalone with automatic profiling and manual adjustments but no adaptive AI learning. The Standard Edition standalone is $29.95 and Professional Edition standalone is $49.95. Free trial downloads are available for all versions in the Try Before Buy format.

Those who want both the Plug-In and the Standalone versions can get the Professional Bundle for $79.90. With the Community Edition offering free licensing and all other versions offering Try-It-First downloads, you can easily find a Noiseware version to match your noise processing needs.
All images on the next few pages were processed with the free Community Edition of Noiseware using automatic processing. Results should be considered baseline as even more effective processing is available with adaptive processing and manual tweaking. The goal here is not to show everything that can be done with a noise reduction program like Noiseware. Rather, we are trying to show the impact of even the lowest level Noiseware processing on images that are considered high ISO noise problems in many reviews. This is to show you what anybody can do to effectively control noise.

agreed. i criticized some earlier reviews, but was holding out for the quality of writing and analysis to improve. that is clearly not happening. even the article synopsis in my anandtech RSS feed was completely wrong:"Not all JPEG processing is created equal, but Noiseware can often fix what camera JPEG processing leaves undone...."
i was truly puzzled by this. noise reduction has NOTHING to do with JPEG compression - that's like saying, "not all gasoline is created equal... let's see how this motor oil performs."
but i guess if it brings in the ad dollars, it's mission accomplished for the site... even though ultimately it's doing the readers a disservice.

You are technically correct, but it appears you are straining to make your point. Certainly you, and everyone else, understands that noise reduction is one of the processes that usually happens during in-camera "JPEG" processing or during software conversion from RAW to a finished image format which is normally JPEG, but could be TIFF or even another format.In the interest of being more precise in the description I have changed it to:
"Not all image processing is created equal, but Noiseware can often reduce noise that in-camera or software processing leaves behind."

thank you for fixing that."Not all image processing is created equal, but Noiseware can often reduce noise that in-camera or software processing leaves behind."
so does gaussian blur! ;)

Eh, I'd say that your quoted caption is an accurate description of the article. There's on-chip noise reduction that is performed before the RAW file is created, then there's software noise reduction that is performed as part of the image processing engine in-camera. The output of that image processing engine is usually JPEG or TIFF, and the RAW preview image.So, if a camera's processing engine isn't running noise reduction before writing to JPEG, then this software would finish the noise reduction stage of post-processing.
As for the software itself, I don't know about the images at full magnification, but the small previews shown indicate fairly heavy smearing. Lightroom does less smearing, and seems to be extremely capable in my experience at chroma noise reduction, and good enough at luminance.
As for writing quality, I can't do better, so I won't criticize.

it is NOT an accurate description. image processing has NOTHING to do with the final output format of the file. you said it yourself - the output could be TIFF, so what does it have to do with "JPEG processing"? call it a nit if you will, but anandtech is a technical publication, so such fundamental inaccuracies should be considered anathema.and saying you can't criticize because you can't do any better yourself seems symptomatic of the sort of mediocrity malaise that results in sub-standard institutions like the US Postal Service. ;) if we expected everything in the world to be no better than what we ourselves can accomplish, the world would be a very sad place...

It's kinda unfair to compare the noise of a Nikon D3 to a Canon XSI, as the Canon has a smaller sensor (as well as a few thousand dollars less)If you wanted to be fair, how about comparing the D3 to a Canon 5D (full frame and less expensive than the d3) or the EOS 1D Mark II or III?

Personally I think there's too much smearing going on, to the point that I like the original picture better. The first picture for example has quite a loss of detail on the windows of the buildings and on the slope of the mountain. In the second picture all the ripples are gone and the boat seems to float above instead of in the water. All non-macro low-iso shots show an incredible amount of smearing (stones on the stairway, vegetation on every background mountain, ripples in water). I don't know how anyone would consider those filtered low-ISO shots an improvement.cparka23 - Monday, July 28, 2008 - link
I've long been impressed w/ Canon's low noise compared to other makes. Up 'til now, I've always heard/assumed that it was the sensor. So is it possible to determine to what exactly the noise reduction is attributable in many cameras? Is it due to an algorithm or is it really the sensor? I guess we'll never know, since the images are already 'processed' in RAW, will we?cparka23 - Monday, July 28, 2008 - link
hmm.. after rereading, that first question didn't come across as I had entirely hoped. regardless, the article helped me understand this a bit.Thanks, Wes.

Canon states that the only noise reduction done to their RAW images is dark noise subtraction. They have plenty of whitepapers on their technology floating around.
