Operation: local snr
Estimate the signal to noise ratio, defined as sne = (foreground mean -
background mean) / background stdDevfor, for each pixel in the image,
based on a region of a given size by applying an otsu-threshold to
the region and counting pixels with an intensity above
the threshold as foreground and other pixels as background.
Options

radius x: radius of the neighborhood in x-direction.
radius y: radius of the neighborhood in y-direction.
Parameter
The only parameter is the input image. The input image must be a 8-bit or 16-bit greyscale image.
Results
Result
(ImagePlus) : A 32 bit image in which each pixel value is the snr
at the corresponding position in the input image. If the background
stdDev is 0 in a region the snr will be "not a number".
Median (ResultsTable): A results table containing the median snr of the image.
