    Abstract

    An image related databased classification system was developed for shoe sole pattern designs. Sole designs are stored with shoe information (brand name, size, style, material, etc.), pattern types and certain features existing on shoe soles or in footwear impressions, and they are used as searching criteria. There are two different classification code systems in the database. Preliminary classification is a very broad classification, and it is meant for shoe sole pattern designs and full shoe sole impressions. Feature classification is designed especially concerning partial footwear impressions, and its classification codes are based on defined basic shapes and certain principles, which facilitate also partial footwear impressions storing, shoe sole designs identifying for partial impressions and the elimination of interpretation error while classifying. User-friendly software makes the classification easy and searches rapid and effective.
