1. A depth estimation from focus method for an image or video processing system, comprising:
receiving input image data containing focus information;
generating an intermediate attention map from the input image data containing focus information by an Artificial Intelligence (AI) model, wherein the AI model is trained by one or more focus-based training materials;
normalizing the intermediate attention map into a depth attention map via a first normalization function; and
deriving expected depth values for the input image data containing focus information from the depth attention map.
