Our research emphasizes on improving the effiency of the
existing system developed by Mitrpont an Kiwprasopask
[1]. Two fudamental concepts are used for developing the
feature extrction and recognition process, i.e., T ai Character
Feature Space and T ai Character Solution Space.
To extrct the composed features frm a character, twelve
featur extrction algorithms are designed to extract the
scanned handwritten document that has been normlized and segmented into individual character image. Ten features are
defmed in Thai Character Feature Space as show in Figure 1.
