This paper presents a new approach for the color display of hyperspectral images. It is proposed to use the one-bit transform (1BT) of hyperspectral image bands to select three suitable bands for red, green, and blue (RGB) display. The proposed approach has low complexity and is very suitable for hardware implementation. A dedicated hardware architecture that computes the transitions in the 1BT of hyperspectral image bands to determine bands that contain more information and the corresponding field-programmable gate array implementation of the proposed architecture are presented. In the proposed approach, less-structured bands are initially eliminated using the total number of transitions in the 1BT of hyperspectral image bands. Then, three suitable bands are selected from within this remaining set of well-structured bands for RGB color display. The proposed approach provides a new method for facilitating the color display of hyperspectral images, which has very low complexity.
