Histogram/SNR Analysis -> go to [Analysis]


Histogram graphs are highly useful in image analysis, as they provide a visual representation of the distribution of pixel intensities. They help users quickly assess contrast, brightness, and exposure levels in an image, making them an essential tool for evaluating image quality and guiding further processing steps.









By selecting the menu options in the order shown in the image above or by choosing the toolbar icon ,
or After selecting a ROI on the image, right-click and choose the 'Histogram/SNR Analysis' option from the menu, as shown below.


the Histo dialog box will be showed up as shown in below picture.

  • ROI
    By allowing users to specify a Region of Interest (ROI) in addition to analyzing the entire image, the analysis speed can be increased, and the accuracy of the analysis can be improved by focusing only on the areas of interest.


  • Pixel Value Range
    This control allows the user to define the pixel value range and set the black level for analysis.


  • SSImXel Analysis Dialog Common Ctrl
    Through this control module, the user can access Help, close or hide the active analysis window, or set it as the top-most window. For more detailed information, please refer here.
