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.

Abstract: Disclosed in embodiments of the present disclosure are a communication method and apparatus, and an electronic device. A specific implementation of the method comprises: in response to a call initiation operation of a multimedia conference, determining a candidate object of the multimedia conference according to an object targeted by the call initiation operation; and displaying, on a multimedia conference interface of the multimedia conference, call state information for the candidate object.
