Abstract
Systems and methods are provided for object extraction from images influenced by depth of field settings. Through control circuitry, an image subjected to a prior segmentation operation is acquired. A subsequent segmentation operation is performed, modulating the depth of field setting to its extreme values, producing two distinct segmented images. From these, an in-focus object is derived, forming delineated representations. A similarity index between representations is computed. If this index exceeds a specified threshold, the in-focus object is extracted from the original image using the control circuitry.
