Hybrid-resolution multispectral imaging is a framework to acquire multispectral images through a reconstruction procedure using two types of measurement data with different spatial and spectral resolutions. In this paper, we propose a new method for such a framework on the basis of a full-resolution RGB image and the data obtained from an image sensor with a multispectral filter array (MSFA). In the proposed method, a small region of each image band is reconstructed as a linear combination of RGB images, where the weighting coefficients are determined using MSFA data. The effectiveness of the proposed approach is shown by simulations using spectral images of natural scenes.
混合分辨率多光谱成像是一种通过重建过程获取多光谱图像的框架，该过程使用具有不同空间和光谱分辨率的两种测量数据。在本文中，我们基于全分辨率RGB图像和从带有多光谱滤光片阵列（MSFA）的图像传感器获得的数据，为这样一个框架提出了一种新方法。在所提出的方法中，每个图像波段的一个小区域被重建为RGB图像的线性组合，其中加权系数使用MSFA数据来确定。通过使用自然场景光谱图像的模拟展示了所提方法的有效性。
