The multiband video camera and display system has developed to increace quality of the video image. The multiband means that there has more than three color channels. The new applications can be created by increasing the number of camera primaries, for example an influence of illumination can be fixed accurately. Furthermore, increasing number of primaries gives a good possibility for image and video processing. However, the growed amount of data causes problems for data transform, store, and process. In this paper, we introduce six band video capturing system and our spectral video database. In the database there is a lot of different type of video clips and the size of spectral video database is more than 300 giga bytes (GB). We also have developed compression scheme for spectral video based on principal component analysis (PCA) and JPEG2000 methods. Here, we concentrate to compress spectral video sequence frame by frame.
Multispectral imaging is receiving attention in medical color imaging, as high-fidelity color information can be acquired by the multispectral image capturing. On the other hand, as color enhancement in medical color image is effective for distinguishing lesion from normal part, we apply a new technique for color enhancement using multispectral image to enhance the features contained in a certain spectral band, without changing the average color distribution of original image. In this method, to keep the average color distribution, KL transform is applied to spectral
data, and only high-order KL coefficients are amplified in the enhancement.
Multispectral images of human skin of bruised arm are captured by 16-band multispectral camera, and the proposed color enhancement is applied. The resultant images are compared with the color images reproduced assuming CIE D65 illuminant (obtained by natural color reproduction technique). As a result, the proposed technique successfully visualizes unclear bruised lesions, which are almost invisible in natural color images. The proposed technique will
provide support tool for the diagnosis in dermatology, visual examination in internal medicine, nursing care for preventing bedsore, and so on.
