Abstract
A single-shot multispectral camera equipped with a filter array has the potential to promote a fast and low-cost multispectral imaging system. We focus on the design of a multispectral filter array and demosaicking in this paper and propose a pathology-specific multispectral imaging system. The spectral sensitivities and patterns of the filter array are optimized by using training data of real pathological tissues. The mosaicked image is demosaicked by considering the designed filter array. We show the effectiveness of the proposed imaging system by comparing the recovered spectrum and RGB image with conventional methods.
