“…Indeed, the NIR-RED band difference index, as proposed by Richardson & Everitt (1992), also showed similar performance as VB-FAH (Figs. 12, 13), suggesting that NIR-RED may be another reliable index for the purpose of detecting and quantifying macroalgae.…”

“…Variations in sun glint might be one of major sources causing uncertainties in using the FAI, VB-FAH, NDVI and NIR-RED (the vertical height extracted by the NIR and red bands, or the band difference, Richardson & Everitt, 1992) indexes to classify macroalgae pixels.…”

“…With the use of two spectral bands red (RED) and near-infrared (NIR), NDVI computes total vegetation coverage area of the basin. This approach of using spectral data improves the utility of predictive change relations for vegetation (Richardson and Everitt 1992). Also, it demonstrates the best vegetation change detection (Lyon et al 1998).…”

“…NDVI is the ratio of difference between the near-infrared and red wavelength bands and sum of those two bands. It is expressed as follows (Richardson and Everitt 1992): where NDVI is Normalized Difference Vegetation Index, NIR is Near Infra Red colour spectral band and RED is Red colour spectral band. This is the most commonly used VI; it has the value in the range of -1 to 1.…”

“…The best known index is the NDVI (Normalized Difference Vegetation Index [8]), which is widely used among researchers. Besides, there are many indices reported in several papers which aim, for example, to reduce the effect of soils' reflectance on vegetation indices (SAVI, TSAVI, PVI) [9,10], to identify water (NDWI) [11] and to determine the water content of vegetation [12] or its chlorophyll content [13]. Finding the best indices becomes complicated as increasing number of bands are involved, i.e.…”
