A Multi-focus Image Fusion Method Based on Laplacian Pyramid
This paper presented a simple and efficient algorithm for multi-focus image fusion, which used a multiresolution signal decomposition scheme called Laplacian pyramid method. The principle of Laplacian pyramid transform is introduced, and based on it the fusion strategy is described in detail. The method mainly composed of three steps. Firstly, the Laplacian pyramids of each source image are dec...
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 کاملImage Data Compression with the Laplacian Pyramid *
Pixel to pixel correlations are first removed by subtracting a low-pass filtered copy of the image from the image itself. The result is a net data compression since the difference, or error, image has low variance, and the low-pass filtered image may be represented at reduced sample density. Further data compression is achieved by quantizing the difference image and repeating the encoding proce...
متن کاملDetailed Description of the Laplacian Pyramid method
This project asks you to study the supplied code for enhancing high resolution medical and scientific images and develop from it a Map-Reduce distributed task that performs the same enhancement – but has the capability to process, in a timely way, images many times the size. The image processing technique uses a Laplacian Pyramid to find and enhance edges in frequency space, and tunes the greys...
