Txhua pixel nyob rau hauv no txoj kab tshiab yog lawm ua tus sau nrog rau xim. Sau xim yog xam los ntawm ib tug tshwj xeeb algorithm. Tus thawj txoj kev - mus sau nyob rau hauv ib txoj kab tshiab ntawm cov xim uas muaj lub tom ntej no pixels. Cov tshwm sim ntawm no ua yuav phem, tab sis xws li ib tug txoj kev yuav tsum tau ib yam tsawg kawg nkaus ntawm computational hauj lwm.

Feem ntau cov feem ntau siv rau lwm txoj kev. Hais tias yog, tshiab kab ntawm pixels no ntxiv rau cov thawj daim duab. Txhua pixel yog lawm ua tus sau nrog rau xim, uas, nyob rau hauv lem, yog xoo li qhov nruab nrab ntawm neighboring pixels. Qhov no txoj kev muab qhov zoo tshaj plaws kev tshwm sim, tab sis yuav tsum tau ntau computational hauj lwm.
