When using the Low Light v3 model in DeNoise v3.6, you may have experienced blotchiness, or patterns, especially in the highlight and shadow regions of very noisy photos. This was due to the Low Light model preserving some of the color in the noise pattern of the original at a very local level, in an effort to provide more consistent color.
To alleviate that issue, we adjusted our approach and reduced that color consistency constraint (say that three times fast 😁) to work on larger regions of the image as opposed to at a very local level. This new approach allows the model to focus on improving noise reduction without worrying about color consistency... yet. That’s because we added a smaller model with the sole purpose of matching the input and output color, thereby establishing improved color consistency of the image after the model processes it.
With these updates, color blotchiness and patterns are significantly reduced, especially in the highlight and shadow regions. The improvements will also be most visible with images suffering from stronger color noise. Here are some examples that illustrate the improvements between Low Light v3 (in DeNoise AI v3.6.2) and Low Light v4 (in DeNoise AI v3.7).
With the implementation of TensorRT models, users who have computers containing NVIDIA GPUs that are 30, 20, or 10 Series will experience model performance improvements. We optimized the library used for NVIDIA GPUs from DirectML to TensorRT and have included these models with the DeNoise AI installer. While users should experience performance boosts with all models, the RAW model will yield especially huge gains when using a supported NVIDIA GPU. Here are two benchmark tests comparing the NVIDIA RTX 3080 and RTX 3060 performance of the DeNoise AI RAW model using DirectML and TensorRT. As you can see, the performance gains are notable.
We’re constantly working to improve our support of new camera model RAW files. With DeNoise AI v3.7, we’ve added support for the Olympus OM1, as well as a number of other camera models. We’ve also improved the JPEG Quality and PNG Compression sliders, giving users more granularity for those settings when saving those respective files. Now, the slider for both formats goes from 1 - 100 instead of 1 - 10.
While DeNoise AI v3.7 has a large number of bug fixes, here are some notable ones:
