+  Drexel-metadata-generator was designed to generate metadata for images
+  of [museum] fish specimens. In addition to the metadata
+  and quality metrics achieved with our initial model
+  (detailed in Automatic Metadata Generation for Fish
+  Specimen Image Collections, bioRXiv), this updated model
+  also generates various geometric and statistical properties
+  on the mask generated over the biological specimen presented.
