Application 1: Book automatic stocktaking

The system uses PicMatch to automatically identify and extract the book back-covers from the images of bookshelves. It then uses PicMatch to perform matching on the images of back-covers to identify the books.

This automatic stocktaking system is used in Japan bookstores to perform stocktaking on their book inventory.

The recognition accuracy has currently reached 92%.



Application 2: Trading-card recognition and stocktaking

Trading-card is a kind of card played in Japan with a large number of patterns and is usually sold in bookstores or game shops.

The challenge is to recognise the patterns of the cards and to identify them during the process of stocktaking.

The system using PicMatch as the image-matching engine has reached the recognition accuracy of almost 100%.
