Digital Correlation based on Wavelet Transform for Image Detection
In this work is presented a method for the optimization of digital correlators to improve the characteristic detection on images using wavelet transform as well as subband filtering. It is proposed an approach of wavelet-based image contrast enhancement in order to increase the performance of digital correlators. The multiresolution representation is employed to improve the high frequency conte...
متن کاملMLP interpolation for digital image processing using wavelet transform
In this paper, we present nonlinear interpolation schemes for image resolution enhancement. The Multilayer perceptron (MLP) interpolation schemes based on the wavelet transform and subband filtering are proposed. Because estimating each sub-image signal is more effective than estimating the whole image signal, pixels in the low-resolution image are used as input signal of the MLP to estimate al...
متن کاملImage Fusion based on Wavelet Transform for Medical Application
Image Fusion is a technique that integrates complementary information from multiple images such that the fused image is more suitable for processing tasks. The paper starts with the study of initial concepts for image fusion. In this paper, the fusion of images from different sources using multiresolution wavelet transform with preprocessing of Image Fusion is proposed. The fused image has more...

15 صفحه اولENEE631 Digital Image Processing: Wavelet-Based Image Compression
In this paper, we discuss methods using the wavelet transform to compress digital images. These methods often employ common image coding strategies such as embedded coding, entropy coding, and subband decomposition, which are described in detail. Then we compare actual image coders that are used in practice based on metrics such as image quality, PSNR, rate scalability, and computational comple...
