RGB images to determine the most accurate DIA method for cover estimation. cover estimations obtained from the different sampling methods used in this study. PQ, photo quadrat; HPF, high pass filter; NSCL, non-supervised classification. obtained by different estimation methods used in this work: VS, visual scan; PQ, photo quadrat; HPF, high pass VS = visual scan; PQ = photo quadrat, HPF, = high pass filter; NSCL= non-supervised classification. information presented in this study shows that the results obtained using digital image Digital image analysis using high pass filters	./cache/work_psa2ky7lvrf45otd344ajv56py.pdf	./txt/work_psa2ky7lvrf45otd344ajv56py.txt
