- W2051264368 abstract "A new technique called two- directional two-dimensional Fisher principal component analysis ((2D) <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> FPCA) in the two dimensional principal component analysis (2DPCA) transformed space is analyzed and its nature is revealed. We first argue that the standard 2D-PCA method works in the column direction of images and subsequently we propose an alternate 2D-FLD which works in the row direction of images in the 2DPCA subspace. To straighten out the problem of massive memory requirements of the 2D-PCA method and as well the alternate 2D-FPCA method, we introduce (2D) <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> FPCA method. The introduced (2D) <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> FPCA method has the advantage of higher recognition rate, lesser memory requirements and better computing performance than the standard PCA /2D-PCA /2D-FLD/2D-FPCA method, and the same has been revealed through extensive experimentations conducted on Finger-Vein dataset." @default.
