Problems solved by technology

However, since pixel intensities are found by integrating over the spectral scale of the incident light, conventional imaging procedures may fail to detect individual spectral components in the incident light that may be able to provide scene-specific or scene-general contrast for object distinguish

Abstract

An imaging system (e.g., hyperspectral imaging system) receives an indication to compare a first object and a second object (e.g., two anatomical structures or organs in a medical environment). The imaging system accesses a classification vector for the first object and the second object, the classification vector having been extracted by separating a plurality of collected reflectance values forthe first object from a plurality of collected reflectance values for the second object. A set of optimal illumination intensities for one or more spectral illumination sources of the imaging system is determined based on the extracted classification vector. The first and second objects are illuminated with the determined illumination intensities. A high-contrast image of the first and second objects is provided for display, such that the two objects can be readily distinguished in the image. The intensity of pixels in the image is determined by the illumination intensities.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional patent application claiming priority from Provisional Patent Application No. 62 / 310539, filed March 18, 2016, the contents of which are hereby incorporated by reference. technical field [0003] The present invention generally relates to generating images with optimized contrast using an imaging system, such as a hyperspectral imaging system. Background technique [0004] The ability to visually distinguish different objects through imaging is critical for many applications. Often, the objects to be discerned are qualitatively different, but may appear similar to the naked eye or during conventional imaging. For example, in medical imaging and surgical imaging, it is very important for the surgeon to be able to distinguish between different anatomical structures. [0005] In conventional imaging, the intensity of a pixel in an image sensor is found by physically integrating over ...
