oidn - Open Image Denoise v2.3.0-beta Latest Release

Published by atafra 6 months ago

  • Significantly improved image quality of the RT filter in high quality
    mode for HDR denoising with prefiltering, i.e., the following combinations
    of input features and parameters:
    - HDR color + albedo + normal + cleanAux
    - albedo
    - normal
    In these cases a much more complex filter is used, which results in lower
    performance than before (about 2x). To revert to the previous performance
    behavior, please switch to the balanced quality mode.
  • Added fast quality mode (OIDN_QUALITY_FAST) for even higher performance
    (about 1.5-2x) interactive/real-time previews and lower default memory usage
    at the cost of somewhat lower image quality. Currently this is implemented
    for the RT filter except prefiltering (albedo, normal). In other cases
    denoising implicitly falls back to balanced mode.
  • Execute Async functions asynchronously on CPU devices as well
  • Load/initialize device modules lazily (improves stability)
  • Added oidnIsCPUDeviceSupported, oidnIsSYCLDeviceSupported,
    oidnIsCUDADeviceSupported, oidnIsHIPDeviceSupported,
    and oidnIsMetalDeviceSupported API functions for checking whether a
    physical device of a particular type is supported
  • Release the CUDA primary context when destroying the device object if using
    the CUDA driver API
  • Fixed device creation error with oidnNewDevice when the default device of
    the specified type (e.g. CUDA) is not supported but there are other
    supported non-default devices of that type in the system
  • Added support for building with ROCm 6.x
  • oidnNewCUDADevice and oidnNewHIPDevice no longer accept negative device
    IDs. If the goal is to use the current device, its actual ID needs to be
    passed.
  • Upgraded to oneTBB 2021.12.0 in the official binaries
