Statistical properties of images.
Structs§
- A set of per-channel histograms from an image with 8 bits per channel.
- A set of per-channel cumulative histograms from an image with 8 bits per channel.
- A minimum and maximum value returned by
min_max()
Functions§
- Returns per-channel cumulative histograms.
- Returns a vector of per-channel histograms.
- Returns the minimum and maximum values per channel in an image.
- Returns the peak signal to noise ratio for a clean image and its noisy approximation. All channels are considered equally. If you do not want this (e.g. if using RGBA) then change image formats first. See also peak signal-to-noise ratio (wikipedia).
- Returns the
p
th percentile of the pixel intensities in an image. - Returns the square root of the mean of the squares of differences between all subpixels in left and right. All channels are considered equally. If you do not want this (e.g. if using RGBA) then change image formats first.
