1.Run separately Ħ°activity_revision_block8.batĦħ and Ħ°flicker_revision_block8.batĦħ, result will write to the file Ħ°activity_outputs.txtĦħ and Ħ°flicker_outputs.txtĦħ 2.Calculate the result in Ħ°activity_outputs.txtĦħ and Ħ°flicker_outputs.txtĦħ follow the function belowed to get the final score of distortion. Function: D=DA*lg(1+DF) (DA is the score in Ħ°activity_outputs.txtĦħ, DF is the score in Ħ°flicker_outputs.txtĦħ)
