Version 1.2.1

  • Release Date: April 17, 2013
  • Requirements:
    • Latest CUDA drivers from NVIDIA [download]
    • CUDA capable Graphics Card [see list]
    • Windows, Linux or Mac OSX
  • New Features/Enchancements

Version 1.2

  • Release Date: May 11, 2012
  • Requirements:
    • Latest CUDA drivers from NVIDIA [download]
    • CUDA capable Graphics Card [see list]
    • Windows 7, Linux or Mac OSX
  • New Features
    • CountInRange - Counts the number of pixels within the given intensity range
    • Sum - Computes the sum of pixel values of each channel in an image
    • Max - Computes the maximum pixel value of each channel in an image
    • Min - Computes the minimum pixel value of each channel in an image
    • MinMax - Computes the minimum and maximum pixel value of each channel in an image
    • Mean - Computes the mean of each channel of the input image
