Abstract :
A thermal infrared camera provides relevant data to observe fine structure of sea skin temperature distribution. The image is exposed to various noises. The authors have developed two algorithms to correct a strip-type noise caused by the scanning mechanism and an inverse shading-type noise caused by spatial inhomogeneity of detecting sensitivity. The first algorithm is based on the two dimensional Fourier transform, and the second one was based on a spatial weighting function. By applying to scanning mode images of MUBEX the authors could confirm the effectiveness of the algorithms
