Abstract
A volumetric imaging system implements obtaining raw image data of a sample volume of a sample material, the raw image data comprising light field data of the sample volume acquired using a microlens array disposed in front of a camera; and analyzing the raw image data using an image analysis pipeline configured to localize the objects of interest in the raw image data to obtain classified image data in which the objects of interest have been identified, the image analysis pipeline being configured to process the raw image data to improve signal extraction at depth in the scattering material to maximize localization accuracy.

A volumetric imaging system comprising:
- a processor;
- and
- a computer-readable medium storing executable instructions for causing the processor to perform operations comprising:
- obtaining raw image data of a sample volume of a sample material, the raw image data comprising light field data of the sample volume acquired using a mesoscope or microscope having a microlens array disposed in front of a camera, the sample material comprising scattering or non-scattering tissue exhibiting time varying changes of light signals from objects of interest;
- and
- analyzing the raw image data using an image analysis pipeline configured to localize the objects of interest in the raw image data to obtain classified image data in which the objects of interest have been identified, the image analysis pipeline being configured to process the raw image data to improve signal extraction at depth in the scattering material to maximize localization accuracy.
