Digital imaging continues expansion to various applications. Spectral images are becoming more popular as one field of digital imaging. In this study we utilize a watermarking method for spectral images, based on the three-dimensional wavelet transform. We study the illumination influence to the watermarked images. The experiments were performed on a large dataset of 58 spectral images. The experiments indicate that using the proposed watermarking method the embedded watermark is robust to the compression attack. Guidelines for the parameter selection for robust watermarking are given.
