One of its main features is the generation of the requested face when it is not found in the existing d... | Face Synthesis (FASY) System for Determining the Characteristics of a

This paper investigates the multiresolution level-1 and level-2 Quotient based Fusion of thermal and visual images. In the proposed system, the method-1 namely "Decompose then Quotient Fuse Level-1" and the method-2 namely "Decompose-Reconstruct then Quotient Fuse Level-2" both work on wavelet transformations of the vi... | Quotient Based Multiresolution Image Fusion of Thermal and Visual Images
Using Daubechies Wavelet Transform for Human Face Recognition | 3,196 |
In this paper fusion of visual and thermal images in wavelet transformed domain has been presented. Here, Daubechies wavelet transform, called as D2, coefficients from visual and corresponding coefficients computed in the same manner from thermal images are combined to get fused coefficients. After decomposition up to ... | Fusion of Daubechies Wavelet Coefficients for Human Face Recognition | 3,197 |
In this paper we present a comparative study on fusion of visual and thermal images using different wavelet transformations. Here, coefficients of discrete wavelet transforms from both visual and thermal images are computed separately and combined. Next, inverse discrete wavelet transformation is taken in order to obta... | Fusion of Wavelet Coefficients from Visual and Thermal Face Images for

Artificial neural networks have already shown their success in face recognition and similar complex pattern recognition tasks. However, a major disadvantage of the technique is that it is extremely slow during training for larger classes and hence not suitable for real-time complex problems such as pattern recognition.... | A Parallel Framework for Multilayer Perceptron for Human Face
