Abstract
A processor for lifetime-based unmixing in fluorescence microscopy is configured to acquire an image having a plurality of pixels, each pixel providing information on photon count and photon arrival times, generate a phasor plot that is a vector space representation of the image, partition the image into image segments, evaluate the image segments according to total photon counts of the corresponding subsets of pixels, and execute a lifetime classification by selecting an image segment having a largest total photon count, determining a region of interest in the image encompassing the image segment, determining a phasor subset in the phasor plot corresponding to the region of interest, and generating a lifetime class including a set of image segments corresponding to the phasor subset. A plurality of lifetime classes is generated by iteratively executing the lifetime classification. The processor is configured to perform lifetime-based unmixing using the life-time classes.
