Image and Video Denoiser on GPU

Image/video denoising is widely used in many applications. We have developed GPU-accelerated denoise kernel that runs on existing hardware from NVIDIA. We have implemented both luma and chroma denoisers and got very high performance both for image and video processing.

GPU Denoiser Library Features

  • Input format: 8/10/12/14/16-bit per channel input data array from CPU or GPU memory
  • Output format: 24/48-bit output data array in CPU or GPU memory
  • High quality and high speed denoise algorithms
  • GUI to show processed data via OpenGL with minimum latency
  • Timing and performance measurements
  • Compatibility with Windows-7/8/10 and Linux/CentOS

Benchmarks for fast image and video denoiser on GPU

Images: 2K image (1920×1080, 24-bit) and 4K image (3840×2160, 24-bit)
Wavelet transform: CDF 9/7
Number or DWT resolutions: 7
DWT thresholds for YCbCr: 10;10;10
Test description: all data in GPU memory, timing includes GPU computations only
Software: OS Windows-7 (64-bit), CUDA-8.0
Hardware: CPU Intel Core i7-5930K (Haswell-E, 6 cores, 3.5–3.7 GHz), NVIDIA GeForce GTX 1080

  • 2K denoising time – 1.78 ms (3.3 GByte/s)
  • 4K denoising time – 5.84 ms (4.0 GByte/s)

We have designed that software as a part of our GPU Image & Video Processing SDK. Now our customers have opportunity to utilize GPU-accelerated denoiser in their applications as a part of general image processing pipeline.

Testing

To test our GPU-based denoiser, please download Fast CinemaDNG Processor software from the download page. We have implemented two types of denoisers: before demosaicing and after demosaicing. Currently that software is working with DNG series and you can get sample set of DNG images at the download page as well.
