The SIGNATURE image processing package is a software package for capturing, editing, compressing and display of signatures. It is mainly intended to be used for financial applications (e.g. banks). It can be provided either in source or in a library format. It can be linked with any banking application and it is the ideal solution on banking hardware platforms that use mainframes connected to PCs through local area networks (LANs) or WANs.Signature has been written in Microsoft C and in Assembly language. Thus, it combines speed and efficiency. It can operate on IBM compatible computers having VGA card and VGA color monitor and 640 KB RAM. It can cooperate with any environment that can be linked with object code coming from MICROSOFT compilers. A signature can be captured, edited and compressed. All relevant information can be passed to the banking software environment in the form of a C structure. This environment is responsible for storing the compressed signature information in a file system (local or remotely accessible through LAN/WAN). The same banking software environment is also responsible for retrieving all relevant information and passing them to SIGNATURE for signature decompression and display. This basic software architecture makes SIGNATURE adaptable to a variety of software environments currently used in the banking sector.
SIGNATURE has two main modules:
Signature Capture, Editing & Compression
The Capture module supports flatbed scanners for A4 page size (one or multiple scanning sites). The scanner currently supported is EPSON GT6000 scanner or compatible. The module is menu and mouse driven and it is very user-friendly. Six user defined Regions-Of-Interest (ROI) can be selected for scanning. Several scanning parameters (e.g. resolution and brightness) can be also user defined. Once a signature is scanned, it can be edited on screen (optional). Editing is mouse driven. When editing is over, the signature image is compressed. The CCITT Huffman Run-Length and the CCITT Modified READ coding methods have been used. Compression ratios range from 1:3-1:10. Besides image editing, the Capture module can also display and edit customer information (company-id, name, tie) that are associated with a specific signature. Both scanning, editing and compression is very fast (in the range of a few seconds). Capture passes the compressed signature to the banking calling environment.
Signature Decompression & Display
The Display module can decompress and display a number of signatures at the same time together with customer data (name and idnumber). The decompression and display is extremely fast (less than 1 second), because it must be used very frequently and in many sites (e.g. tellers). Signatures are grouped into pages and can be browsed by using F7-F8, PgDn, PgUp, Home, End and arrow keys.
