No...you need image classification software generally associated with the remote sensing field...manual digitizing is your best bet should you not have the aforementioned available

Make a mosaic dataset. Then use the build footprints tool. Set maximum data value to 254 and number of vertices to 20. Tick the maintain sheet edges, Tick Overviews and Update Boundaries boxes. Run the tool. Then bring the mosaic into arcmap and export the boundaies as a shapefile.

Let me know if this works for you.

Here is what I did, it´s well explained in this video:

1) Create signature
2) Then Maximum Likelihood Classification (SA)
3) Convert �??Raster to Polygon�?�

Nice one. Keep my method in mind because when you start using the raster to polygon tool on larger data sets the tool will fail. All the best.
