The paper proposes a Modified Principal Component Analysis coined as 2DPCA to compare 2D and 3D face recognition. In 2DPCA a covariance matrix of image is obtained directly from the original image and is used to find the eigenvectors for image feature extraction. Here the Texas 3D [1] face recognition database was considered, which has 1149 pairs of high(More)
The Adders are the critical elements in most of the digital circuit designs, including digital signal processors (DSP) and microprocessors. Extensive research has gone into the VLSI implementations of Parallel Prefix Adders which are known for their best performance. The performance of Parallel Prefix Adders is directly affected by the constraints in the(More)
