 Sharpness for each pixel is calculated based on the values of immediately surrounding it pixels, only the luma component \(L\) is used for this calculation. Sharpness for each pixel is calculated based on the values of immediately surrounding it pixels, only the luma component \(L\) is used for this calculation.
  
-A pixel'​s new value is calculated based on the simple matrix (see below) with a little twist: the central coefficient of 5 is adjusted based on the new value of sharpness as follows: \(coef_5 = 5 + sharpness\),​ where \(sharpness\) is in range ''​[-1..+1]''​.+A pixel'​s new value is calculated based on the simple matrix (see below) with a little twist: the central coefficient of 5 is adjusted based on the new value of sharpness as follows: \(coef_5 = 5 + sharpness\),​ where \(sharpness\) is in range \([-1..+1]\).
