چکیده
Šume primorskih ?etinja?a, sa svojom ekološkom, ekonomskom, estetskom i društvenom funkcijom, predstavljaju važan dio europskih šumskih zajednica. Osnovni cilj ovoga rada je usporediti najkorištenije GEOBIA (engl. Geographic Object-Based Image Analysis ) klasifikacijske algoritme Random Trees – RT, Maximum Likelihood ML, Support Vector Machine SVM s ciljem izdvajanja šuma ?etinja?a na visoko-rezolucijskom WorldView-3 snimku unutar topografskog slijevnog podru?ja naselja Split. Metodološki okvir istraživanja uklju?uje (1) izvo?enje izoštrenog multispektralnog snimka ( WV-3<sub>MS</sub> -a) ; (2) testiranje segmentacijskih korisni?ko-definiranih parametara; (3) dodavanje testnih uzoraka; (4) klasifikaciju segmentiranog modela; (5) procjenu to?nosti klasifikacijskih algoritama, te (6) završnog modela. RT se prema korištenim pokazateljima correctness COR , completeness COM overall quality OQ pokazao kao najbolji algoritam. Iterativno postavljanje parametara omogu?ilo detekciju najprikladnijih vrijednosti za generiranje segmentacijskog Utvr?eno da sjene mogu uzrokovati zna?ajne probleme ako klasificiranje vrši visoko-rezolucijskim snimkama. Modificiranim Cohen’s kappa coefficient (K) pokazateljem izra?unata to?nost kona?nog modela od 87,38%. može smatrati kvalitetnim podatkom primjenom metode.

This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
