If you mean changing the camera setting to use a higher resolution, then
yes this should improve results...

hi all, when using "arDetectMarker(dataPtr, thresh, &marker_info, &marker_num)" to get marker infomation from the "dataPtr" abtained from arVideoGetImage() , is it feasible to track more precisely and stable by enlarging the captured image size?
