Detection of Multiple Faces in Color Images using Haar Wavelets
Face detection is a very challenging and interesting problem. In this paper, a new scheme for detection of multiple faces using Haar wavelet packet decomposition based on quantized skin color region merging under unconstrained scene conditions is presented. Color clustering and filtering using approximations of the YCbCr and HSV skin color subspaces are applied on the original image by providin...
متن کاملImage Fusion Using Laplacian Pyramid Transform
1. Abstract The objective of image fusion, is to make use of the complementary information in multiple images, to achieve a higher resolution and intelligibility. The fused images provide more comprehensive and more precise description, which is more suitable for human visual system and machine perception or further image-processing tasks. In this project, our goal is to obtain a single image, ...
متن کاملMultiple Image Fusion Using Laplacian Pyramid
Image fusion is an important visualization technique of integrating coherent spatial and temporal information into a compact form. Laplacian fusion is a process that combines regions of images from different sources into a single fused image based on a salience selection rule for each region. In this paper, we proposed an algorithmic approach using a Laplacian and Gaussian pyramid to better loc...
متن کاملAn improved least squares Laplacian pyramid for image compression
This paper describes two ways of improving Burt and Adelson's Laplacian pyramid, a technique developed for image compression. The Laplacian pyramid is a multi-resolution image representation that captures the loss of information occurring through repeated reduction of the spatial resolution. The generation of this data structure involves the use of two complementary functions: EXPAND, which inc...

In the present paper, we show that by computing <:ross-correlation within each level of the pyralnid independently, and considering the surn across (expanded) levels, a significant improvement in Peak to Correlation Energy (PCE) [9] is obta...
