An interactive color visualization method with multi-image fusion for hyperspectral imagery

An interactive color visualization method is proposed for hyperspectral imagery (HSI). The method visualizes complex information through different fusion results of multiple images in a color space which is under the interactive control of the observers. In order to solve the main problem of traditional visualization methods, i.e., they can at most display information from three bands in one image, this paper proposes an easy, vivid and effective method for color visualization. In the proposed approach, observers interactively control a cursor position to change the output fusion images and their fusion coefficients. In the approach, the dynamic display will include more than three bands of HSIs. The proposed method is also applicable for visualization of other multi-images, e.g., multispectral images, output images of direction filters, multi-focus images, and multi-temporal images, etc.
