Concretely, a U ^ 2-Net segmentation model imayembekezera per-pixel alpha matte ndipo kumbuyo kwakuyenera kugawidwa - koma kuwonongeka kwa malo ali ndi maziko olimba, ophatikizidwa, kotero kuti matte imakhala yolimba pambuyo pake, ndipo zotsatirazi ziyenera kupita ku mtundu ndi alpha channel kuposa kumbuyo kwa lossy. There is no manual masking step — a neural segmentation model does the separation and you get a transparent result back.
Kodi ndi yotani yoyenera ndi cut-out pa mapiko ovuta?

Mafunso olimba m'mbuyomu amadziwika bwino. Maluwa abwino, maonekedwe, kuwala kwa motion, mawindo ndi masamba a chain-link ndi malo omwe machitidwe onse osinthika amalimbana, ndipo komwe mungafune kukhudza zotsatirazo ndi manja pambuyo pake.
Kodi mtundu wanga wa malemba amakhudza bwanji ubwino wa filimu yosaoneka bwino?
+
Yes. JPG imasunga RGB ya 8-bit pogwiritsa ntchito DCT yopanda phindu ndi 4: 2: 0 chroma subsampling mosalekeza, kotero malemba oyera ndi olimba ndi zinthu zoyamba zomwe zimayenera kuchepetsedwa. Compression artefacts m'mawu a m'mawu ndi zomwe ziyenera kuchitidwa ndi segmentation model, kotero kulowa koyera kumapatsa chida choyera.
Pali china chilichonse chokhudzana ndi JPG chomwe ndingaganizire?
+
Yes — zonse kupulumutsa re-kuyenda kwa quantumiser, choncho nthawi zambiri kusinthira ndi kubwezeretsa JPG kumapangitsa kuwonongeka kwa chitukuko ngakhale mutatha kuchepetsa slider yabwino. Izi zimapanga zomwe model imawona komanso zomwe zitha kubweretsa zotsatira.
Kodi chimachitika ndi EXIF ndi mtundu wa profile deta?
+
EXIF ya kamera (ISO, shutter, lens, GPS) ndi ICC profile yophatikizidwa imapita ku default, chifukwa kuchotsa profile ndi komwe kumachititsa kuti mabala azisintha pa kulowanso.
Kodi Sungani JPG kumbuyo imawononga chilichonse?
+
No. Sungani JPG kumbuyo ndi ufulu popanda akaunti, palibe watermark pazotulutsa ndi palibe khoma lolembetsa m'mbuyo mwa kutsitsa. Kutsitsa kumatha kuchotsanso nthawi yochepa pambuyo pomaliza ntchito.
