An automated matching program for flank and ventral surface patterns on grey seals is not currently available.   However, the current harbour seal program may be usable with grey seal images.  The pattern extraction software developed for grey seal head/neck patterns (which has been used to build catalogues for the North Sea, Irish Sea and the Baltic Sea) is not suitable for distribution, however we can add pattern extracts from submitted digital images to new or existing catalogues. We can also carry out the visual confirmation stage and supply an updated database of matching results or alternatively supply software for the user to complete the visual confirmations.
