Analysis of Features for Efficient Japanese Vowel Recognition Takeshi SAITOH Mitsugu HISAGI Ryosuke KONISHI Publication IEICE TRANSACTIONS on Information and Systems Vol.E90-D No.11 pp.1889-1891 Publication Date: 2007/11/01 Online ISSN: 1745-1361 DOI: 10.1093/ietisy/e90-d.11.1889 Print ISSN: 0916-8532 Type of Manuscript: LETTER Category: Pattern Recognition Keyword: lip-reading, feature, vowel recognition, Full Text: PDF(451.4KB)>>
Summary: This paper analyses the features required to efficiently recognize five Japanese vowels for lip-reading. Various features, such as shape and radius, are calculated from the lip region and fed to the k Nearest Neighbor method. We calculated 15 feature sets and found that the feature set including the area and aspect ratio of the mouth cavity is effective for Japanese vowel recognition. | ||||||||||
