Description
|
|
|
•
|
The Quality command computes the quality measure of a reconstructed image with respect to a source image.
|
|
•
|
The img_r and img_s parameters are the reconstructed and the source images, respectively. They must be grayscale images and have the same width, height, and order (C_order or Fortran_order).

Quality Measures
|
|
|
|
The optional meas parameter is a name specifying the quality measure. It can take one of the following values, the default is mse:
|
|
•
|
rmse: root-mean-squared error (rms).  .
|
|
•
|
snr: signal-to-noise ratio. /(w h mse))](/support/helpjp/helpview.aspx?si=3785/file01962/math122.png) .
|
|
•
|
psnr: peak signal-to-noise ratio. ](/support/helpjp/helpview.aspx?si=3785/file01962/math127.png) .
|
|
|
|
|
Options
|
|
|
|
Specifies the peak value to use for the peak signal-to-noise ratio (psnr) calculation. It is ignored for the other cases. The default is 1.
