![]() The general model we present is able to denoise new datasets without additional training. By training on a dataset composed of thousands of micrographs collected across a wide range of imaging conditions, we are able to learn models capturing the complexity of the cryoEM image formation process. Here, we present Topaz-Denoise, a deep learning method for reliably and rapidly increasing the SNR of cryoEM images and cryoET tomograms. Denoising cryoEM images can not only improve downstream analysis but also accelerate the time-consuming data collection process by allowing lower electron dose micrographs to be used for analysis. Low signal-to-noise ratio (SNR) in cryoEM images reduces the confidence and throughput of structure determination during several steps of data processing, resulting in impediments such as missing particle orientations. But for me, it is less desirable than an NR tool that offers me more localized control.Cryo-electron microscopy (cryoEM) is becoming the preferred method for resolving protein structures. PureRaw does a fine job, but does its "take it or leave it" approach to these issues really reduce its overall value? THAT is something each of us ultimately must decide for ourselves. I have recently learned that Lr's noise reduction has this ability as well. That doesn't mean I'm going to get rid of my Topaz tools though, they are paid for, and they might have some value for SOME photos.īoth On1 and the Topaz tools have the ability to selectively mask areas of the photos for NR and sharpness, and then subsequently modify overall sharpness and NR if it isn't perfect. ![]() I recently bought On and I am quite satisfied with it's ability to control noise and sharpness in high ISO ORF files. But I do think they ultimately lead to false assessments of overall value. These things are fun to view and fun to make. The biggest problem with these types of articles is that they bog us down in minute differences when the truth is, all "AI" software of this sort is good enough for most people and most uses. That hasn't happened before the update ever and i eas just zooming in and out to compare the results. By the way LRC crashed my MacBook twice I mean completely nothing not even the mouse worked and then restarted by itself. So this was not a a picture with bad noise and i know that Topaz DeNoise AI does a really good jobeven with a lot of noise and i do use the Sharpen AI sometimes as well and works great. Speed wise i would say LRC DeNoise AI was a little faster, but not better in the end result. LRC doesn't give you much settings to change. So if i compare all three Topaz is still the winner because it not only removed noise but add sharpness to the picture and i can change settings if i don't like the results. ![]() ![]() Topaz DeNoise AI removed Noise and contained sharpness a touch better then LRC DeNoise AI. New LRC DeNoise AI removed Noise very welland fast, but still a little soft when zooming in. Denoise manual in LRC removed most of the noise, but made picture soft as well. ![]() noise wasn't to bad on the picture, but there was some. The picture i used foe now was shoot indoors with a Nikon D750 no flash ISO set to Auto -> 4500, tamron dx 18-400mm set to 35mm, f5.6 and speed to 1/320 sec (all manuel except iso). So I updated LRC just now to see how this new DeNoise Ai works. I have been using Topaz DeNoise AI and Topaz Sharpen AI about a year now and really like the results. ![]()
