A system for recognizing numeric strings from topographical maps
نویسندگان
چکیده
This paper proposes a system for recognizing numeric strings from topographical maps, which is composed of the automatic recognition stage and the interactive recognition stage. In this method, uncertain numeric strings extracted through the automatic recognition stage based on topographical map feature only, are confirmed and corrected by the interactive recognition stage. Therefore we can obtain high precise recognition results. The method was applied to numeric string recognition from map image which include 102 strings made up of 249 numerals. As a result, 95.1% of 102 numeric strings were correctly recognized.

Recognition of Numeric Strings with Notation Rules Using String Checking
At1 algorithm ,for recognizing nutvreric strings with notation rules by using string checking has been developed. The proposed string check function removes extraneous characters from recognized character strings by using the notation rules. This function also determines whether to carry out recognition error correction. In this correction process, recognized characters are compared with string...
متن کاملProcessing Symbolic Data With Self-Organizing Maps
Current research on machine learning and related algorithms is focused mainly on numeric paradigms. It is, however, widely supposed that intelligent behavior strongly relies on ability to manipulate symbols. In this paper we present on-line versions of self-organizing maps for symbol strings. The underlying key concepts are average and similarity, applied on strings. These concepts are easily d...
متن کاملConstruction of a System for Recognizing Touch of Strings for Guitar
In guitar performance, fingering is an important factor. In particular, the fingering of the left hand comprises various relationships between the finger and the string, such as the finger touching/pressing/releasing the strings. The recognition of the precise fingering is applied to a self-learning support system, which is able to detect strings being muted by a finger, and which transcribes m...

متن کاملPattern recognition algorithms for symbol strings
Traditionally, pattern recognition has been concerned mostly with numerical data, i.e. vectors of real-valued features. Less often, symbolic representations of data have been used. A special category of data, symbol strings, have been neglected for a long time, partially because of a perceived lack of urgency and partially because of the high computational costs involved. Only recently, motivat...
