1. A method for providing low lighting adjustments within a video communication session, comprising:
receiving video content within a video communication session of a video communication platform, the video content having multiple video frames;
generating a lighting adjustment request comprising a lighting adjustment depth that defines a threshold for classifying a region of a video frame into rough texture sub-regions and smooth texture sub-regions;
segmenting the region of each video frame of the multiple video frames into rough texture sub-regions and smooth texture sub-regions based on the threshold;
smoothing areas adjacent to the rough texture sub-regions to a degree less than areas adjacent to the smooth texture sub-regions;
detecting an amount of lighting in the video content using an artificial intelligence model that interprets a geometric reconstruction of a scene from the video content; and
modifying the video content to adjust the amount of lighting based on the scene, wherein the amount of adjustment of lighting corresponds to the lighting adjustment depth, and wherein adjusting the amount of lighting is performed in real time or substantially real time upon receiving the lighting adjustment request.
