Enblend uses nearest feature transform to place initial seam line (line where one image blends to another). Then it uses difference to "detect" objects and moves the seam line (this movement is done only in X axis I think) to avoid any intersections with the object. Some informations about it are on enblend website [1]. There is also record [2] of Andrew's talk about enblend and enfuse on LGM 2009 which contains many interesting informations (you should really see that). Talking about enfuse there is no support to avoid artifacts caused by moving objects directly in enfuse (because direct integration of the algorithm used in aforementioned tools didn't lead to acceptable results). There is deghosting_mask tool which tries to create B/W images where moving objects should be black. These images can be used with enfuse-mask to remove objects using enfuse. For HDR output you can use merge mode "Deghosting (Khan)" (it can be selected in Stitcher tab, HDR merger options). Both uses the same algorithm which tries to determine whether pixel belongs to static part of image or not. The problem is that it's utterly slow and the quality of result is highly dependent on input images.
