Image Degradation for Quality Assessment of Pan-Sharpening Methods
Abstract: Wald’s protocol is the most widely accepted protocol to assess pan-sharpening algorithms. In particular, the synthesis property—which is usually validated on a reduced scale—is thought to be a necessary and sufficient condition of a success image fusion. Usually, the synthesis property is evaluated at a reduced resolution scale to take the original multispectral (MS) image as referenc...
متن کاملEvaluation of Pan-Sharpening Methods
Melissa Strait, Sheida Rahmani, Daria Markurjev Faculty Advisor: Todd Wittman UCLA Department of Mathematics August 2008 Abstract Pan-sharpening combines a low-resolution color multispectral image with a high-resolution grayscale panchromatic image to create a high-resolution fused color image. In this paper we examine five different pan-sharpening methods: IHS, PCA, Wavelet fusion, P+XS, and V...
متن کاملEvaluation of Fusion Methods: Pan-Sharpening Methods
Image fusion in the field of remote sensing deals with combination of multispectral and panchromatic image. The idea of such combination is to derive best information out of it. A multispectral image is spectral rich whereas a panchromatic image is spatially sound so their combination gives better information in terms of best spatial and spectral parameters. This Paper aims at evaluating variou...
متن کاملCompressive Sensing for Pan-sharpening
Based on compressive sensing framework and sparse reconstruction technology, a new pan-sharpening method, named Sparse Fusion of Images (SparseFI, pronounced as sparsify), is proposed in [1]. In this paper, the proposed SparseFI algorithm is validated using UltraCam and WorldView-2 data. Visual and statistic analysis show superior performance of SparseFI compared to the existing conventional pa...
متن کاملApplication of Different Pan-sharpening Methods on Worldview-3 Images
In the field of the remote sensing, the introduction of high resolution satellite sensors has required the development of several data fusion approaches. Two kinds of images are usually acquired: multispectral and panchromatic. The first group has a lower spatial resolution but accurate spectral information while the second presents a higher spatial resolution with a longer band acquisition ran...
