چکیده

In this paper we propose fast face recognition system based on the 1-D Discrete Slant Transform (ST) row feature vector-RV and column feature vector-CV. This scheme is less complicated and needs less time as compared to ST of full image. It is observed that in this method for 95% image energy the coefficient requirement reduces drastically compared to PCA and full ST. Thus computational burden decreases and recognition time reduces. We have used standard ORL database and results obtained are accurate. The algorithm is also tested for locally created database of male and female faces which gives accuracy around 90%.

Image Compression Using Column, Row and Full Wavelet Transforms Of Walsh, Cosine, Haar, Kekre, Slant and Sine and Their Comparison with Corresponding Orthogonal Transforms

In this paper, image compression using orthogonal wavelet transforms of Walsh, Cosine, Haar, Kekre, Slant and Sine is studied. Wavelet transform of size N 2 xN 2 is generated using its corresponding orthogonal transform of size NxN. These wavelet transforms are applied on R, G, and B planes of 256x256x3 size colour images separately. In each transformed plane rows/columns are sorted in their de...

تشخیص چهره با استفاده از PCA و فیلتر گابور

Methods for face recognition which are based on face structure are among techniques without supervision and produce unfavorable results in the presence of linear changes in images. PCA is a linear transform and a powerful tool for data analysis but does not produce good results for face recognition when there are non-linear changes resulting from changes in position, intensity and gesture in th...

(2D)PCA: 2-Directional 2-Dimensional PCA for Efficient Face Representation and Recognition

Recently, a new technique called 2-dimensional principal component analysis (2DPCA) was proposed for face representation and recognition. The main idea behind 2DPCA is that it is based on 2D matrices as opposed to the standard PCA, which is based on 1D vectors. Although 2DPCA obtains higher recognition accuracy than PCA, a vital unresolved problem of 2DPCA is that it needs many more coefficient...

Performance Analysis of Watermarking using SVD of watermark in Non-sinusoidal Column and Row Transforms

A novel watermarking technique using Singular Value Decomposition (SVD) and non-sinusoidal column/row transforms like Haar, Walsh, Slant and Discrete Kekre Transform is proposed in the paper. Host images are subject to column/row transform using orthogonal non-sinusoidal transforms and watermark is subjected to SVD. To prevent loss of watermark after performing attacks on watermarked image, wat...

Two-Dimensional Optimal Transform for Appearance Based Object Recognition

This paper proposes a new method of feature extraction called twodimensional optimal transform (2D-OPT) useful for appearance based object recognition. The 2D-OPT method provides a better discrimination power between classes by maximizing the distance between class centers. We first argue that the proposed 2D-OPT method works in the row direction of images and subsequently we propose an alterna...
