Title
Enhanced visualization of hyperspectral images
Author
Abstract
We present an enhanced visualization algorithm for hyperspectral images (HSIs). The visualization is based on the projection onto color matching functions of the human vision system. A contrast enhancement procedure is introduced by the fusion of the gradient information of the individual HSI bands. Both visualization and enhancement are combined into a multiresolution framework using wavelets. The HSI is transformed into a specific representation (HSI wavelet representation), in which the enhancement is performed at the level of the wavelet detail subbands, whereas the visualization is performed at the level of the low-resolution subbands. Specific objective quality measures are applied to demonstrate that the proposed procedure provides visualization results with a high contrast. Results are compared with state-of-the-art HSI visualization techniques and with the postprocessing enhancement.
