Sir, here I filtered grayimage using mean,median,gaussian,wiener filter but i dont know how to measure filtered results. In one research paper filtered result were mea-sured by calculating their TV values, so my question is how to calculate TV values. the following table specifies TV values those are from reserach paper.
