U drugoj metodi modelovanja statue maske (alfa kanal fotografije) smo kreirali u Photoshop-u i kao takve ubacivale u Agisoft PhotoScan<\/strong>.<\/p>\n

Postupak rada:<\/p>\n

1. Upload-ujemo sliku u Photoshop i prebacimo se na chennel<\/p>\n

\"1\"<\/a><\/p>\n

2. Dupliciramo lejer RED<\/strong> i pritisnemo ctrl+i kako bismo inverzovali boje jer “svijetlo” treba da bude tako gdje je statua<\/p>\n

\"2\"<\/a><\/p>\n

3. Zatim idemo na Image-calculate<\/strong> i postavimo da je red source 1 <\/strong>a blue source 2 <\/strong>i izaberemo substract<\/strong> kao blending mode<\/strong><\/p>\n

\"3\"<\/a><\/p>\n

4. Selektujemo novi alfa kanal; Izaberemo opciju pen<\/strong> i pa\u017eljivo iscrtamo konture statue;
\nZatim alatkom path selection tool<\/strong> selektujemo nacrtanu stazu; Desni klik na nju i izaberemo select path<\/strong> i jednostavno je obri\u0161emo<\/p>\n

\"4\"<\/a><\/p>\n

5. Na istom kanalu izaberemo alatku brush<\/strong> opacity: 100, mode overlay<\/strong> i pre\u0111emo preko fotografije; Ovim postupkom on \u0107e potamniti sve osim prethodno izabrane staze<\/p>\n

\"5\"<\/a><\/p>\n

Na ovaj na\u010din dobijemo alfa kanal<\/strong><\/em>\u00a0<\/strong>koji nam je potreban za Agisoft Photo Scan.<\/strong><\/em>\u00a0<\/strong>Dalji proces rada je isti kao u ve\u0107 nazna\u010denom postupku 1<\/strong>.<\/p>\n

6. Maske se ubacuju sa opcijama: Tools – Import – Import Masks – <\/strong>na kartici izaberemo Active chunk,\u00a0 <\/strong>potvrdimo radnju i dobijemo mogu\u0107nost biranja odredjenog foldera kako bi ubacili maske<\/p>\n

\"Untitled-1\"<\/a>\u00a0\u00a0\u00a0\u00a0 \"ff\"<\/a><\/p>\n

7. Finalni proizvod Agisoft Photo Scan-a:<\/p>\n

\"ovaj\"<\/a>\u00a0\u00a0\u00a0\u00a0 \"ovaj1\"<\/a><\/p>\n
