Note on Set Cover
Greedy: Θ(min(logd,q)): Θ(H(d)) (this also implies O(logn), n is number of elements). (Note: Feige [3] prove that there is no substantially improvement (for greedy algo).) Also O(q) and exists tight example (section 2.5); so, Θ(q) in general. Note that this bound is asymptotically tight (see Vazirani’s book [10] section 29.9) Slav́ık [9] also gives exact analysis lnn− lnlnn+Θ(1). LP Rounding: O(...
متن کاملstudy of flight height and spatial resolution of aerial photography in estimating canopy cover percentage of shrub lands
remote sensing and aerial photographs are used to produce medium to small scale images. however, for detailed information especially to estimate rangeland vegetation canopy cover there is a need to larger scale images. it is therefore necessary to study the technical applicability of different devices such as short range light airplanes, kites, gliders and balloons. in this research, we focused...
متن کاملEstimating vegetation height and canopy cover from remotely sensed data with machine learning
6 High quality information on forest resources is important to forest ecosystem management. Tra7 ditional ground measurements are labor and resource intensive and at the same time expensive 8 and time consuming. For most of the Slovenian forests, there is extensive ground-based infor9 mation on forest properties of selected sample locations. However there is no continuous infor10 mation of obje...
متن کاملMeasurement of Crown Cover and Leaf Area Index Using Digital Cover Photography and Its Application to Remote Sensing
Digital cover photography (DCP) is a high resolution, vertical field-of-view method for ground-based estimation of forest metrics, and has advantages over fisheye sensors owing to its ease of application and high accuracy. We conducted the first thorough technical appraisal of DCP using both single-lens-reflex (DSLR) and point-and-shoot cameras and concluded that differences result primarily fr...
متن کاملDigital Cover Photography for Estimating Leaf Area Index (LAI) in Apple Trees Using a Variable Light Extinction Coefficient
Leaf area index (LAI) is one of the key biophysical variables required for crop modeling. Direct LAI measurements are time consuming and difficult to obtain for experimental and commercial fruit orchards. Devices used to estimate LAI have shown considerable errors when compared to ground-truth or destructive measurements, requiring tedious site-specific calibrations. The objective of this study...
