1. An image processing system for an extended reality, XR, device, the image processing system comprising:
an eye-tracking subsystem configured to track an eye of a user for determining a focus region of the eye;
at least one processor configured to:
process application data to render image content for an application for display on the XR device;
obtain metadata indicating that a virtual object is to be generated as a hologram as part of the image content for display;
based on a determination that the virtual object belongs to a predetermined class of objects and is to be displayed in the focus region:
perform, using a neural network corresponding to the predetermined class of objects, foveated processing of the image content, including at least part of the hologram, such that relatively high-quality image content is generated for display in the focus region and relatively low-quality image content is generated for display outside the focus region.
