Abstract
Methods and systems for determining parameters of a desired target image from hyperspectral imagery obtained from a surgical procedure are described herein. Techniques may include capturing in real time hyperspectral snapshot mosaic images of a scene using a hyperspectral image sensor coupled to an optical scope, the snapshot mosaic images being of relatively low spatial and low spectral resolution; undertaking spatio-spectrally aware demosaicking of the snapshot mosaic images, the demosaicking comprising upsampling of the snapshot mosaic images and the application of a spectral calibration operator, to generate a virtual hypercube of the snapshot mosaic image data, the virtual hypercube comprising image data of relatively high spatial resolution compared to the snapshot mosaic images; from the image data in the virtual hypercube, determining relatively high spatial resolution parameters of a desired target image; and outputting in real time the determined relatively high-resolution parameters as representative of the desired target image.
