The color enhancement of multispectral images is a useful tool to visualize their spectral features. Previously, a color enhancement method which enhances the feature of specified spectral band without changing the average color distribution was proposed. However, the enhanced feature is sometimes unapparent or invisible, when the wavelength range of the specified band is visually insignificant. In this paper, we propose a modified method for more effective visualization capability in the color enhancement for multispectral images. In the proposed method, a user specifies both the spectral band for extracting the spectral feature and the color to be visualized, respectively. Then, the spectral feature in the multispectral image is enhanced by arbitrary color. The proposed method of the color enhancement was experimentally applied to multispectral images, such as a human skin image and microscopic images of pathological tissue specimen. As a result, we verified that the proposed method can effectively visualize the spectral features.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
