Cov kev ntsuas no kuj tseem yuav tsum tau kho dua yog tias koj lub txaj nyob hauv qhov chaw zoo sib xws. Feem ntau, koj yuav xav tau erode_dim siab dua rau qhov sib txawv siab teeb tsa, thiab qis erode_dim rau qhov sib txawv qis.

Yog tias koj ua haujlwm CribSense nrog show_diff = qhov tseeb thiab koj pom tias ntau dhau ntawm cov khoom tso tawm yog dawb, lossis qee qhov tsis cuam tshuam ib feem ntawm cov vis dis aus raug kuaj pom tias yog suab (piv txwv li lub teeb ci), nce erode_dim kom txog thaum tsuas yog ib feem ntawm cov vis dis aus sib thooj rau koj tus menyuam yog qhov loj tshaj plaws ntawm dawb. Thawj daim duab qhia pom ib qho piv txwv uas qhov kev tshem tawm ntawm qhov qis dhau rau qhov kev txav ntawm tus ncej, thaum tus tom ntej no qhia tau tias zoo li tus qauv ntsuas.

Thaum qhov no tau ntsuas, nco ntsoov tias pixel_threshold tau teeb tsa tus nqi xws li "Pixel Movement" tsuas yog tshaj tawm qhov txiaj ntsig siab tshaj ntawm kev txav pixel, thiab tsis yog txhua tus (uas txhais tau tias koj yuav tsum txiav tawm lub suab nrov). Qhov zoo tshaj, koj yuav pom cov txiaj ntsig zoo li qhov no hauv koj lub davhlau ya nyob twg, qhov twg muaj cov qauv zoo ib ntus sib xws rau cov lus tsa suab:
