Computes BRISQUE quality score for input image

Positional Arguments

• self: Evision.Quality.QualityBRISQUE.t()

• img: Evision.Mat.t().

  Image for which to compute quality

Return

• retval: cv::Scalar

@returns cv::Scalar with the score in the first element. The score ranges from 0 (best quality) to 100 (worst quality)

Python prototype (for reference only):
