    Simulated Spectral Light Transport in Coastal Waters Using Adaptive Photon Mapping



    This poster addresses the so-called boundary bias associated with Photon Mapping [Jensen 2001] as well as bias resulting from sparsely populated spectral maps. This work is done in the context of modelling spectrally and spatially variant coastal waters for remote sensing applications. We are particularly interested in simulating hyperspectral scenarios where it will be necessary to model detectors that are sensitive to tens, if not hundreds, of wavelengths. This new approach differentially searches the photon map based on boundary distances and spectral bands. It is being developed within a ray-tracing environment known as DIRSIG [Schott et al. 1999], which is used for modelling remote sensing scenarios and developing algorithms for the terrestrial regime. The current work is a key element in extending its capabilities to the littoral and oceanic domain. The final water modelling environment will be used to develop water quality and underwater target detection algorithms based on existing remote sensing platforms and to quantitatively define the design requirements of future remote sensing systems.
