A New Feature Extraction of Forms Recognition
Dongxiao Zhang · Jisuanji gongcheng · 2006
A method of forms identification is introduced,which can be employed in processing of documents with a certain style of application form.In order to solve the identification of such forms with a symmetry figure,a new approach of feature extraction is presented,which is a method of area division done by partition the forms image into areas.Both the horizontal feature and the vertical feature of forms image are token into account,and the power spectral density of the subareas’ profile is used as forms image’s feature vector.It is shown to be an effective method to identify the forms with symmetry figure.
