ABSTRACT: 
For high spatial resolution Remote Sensing images, it is very important to investigate the transformational methods between 
background and target characteristics. Only in this way rich details in images under different imaging conditions can be well 
extracted. Amongst the characteristics of imagery targets, texture is a visual feature that reflects the homogeneity of images and the 
inner attributes of different objects. What’s more, it includes important information which describes the structural arrangement of 
objects and the connection with the surrounding environment. This paper regards texture as the major feature and investigates the 
transformational methods of texture feature description under different imaging conditions. 
This paper mainly consists of three parts:(1) Construct a wavelet filter based on Gabor wavelet, which describes texture features 
obtained under different imaging conditions;(2) Process and analyze the different object’s texture features jointly by the relationship 
which is built by the wavelet description;(3) Build the transformation between the wavelet descriptions of the different object’s 
texture features based on the characteristics of the band and direction. 
1. INTRODUCTION 
As a natural attribute of subjects, texture is a visual feature that 
reflects the homogeneity of images. People have researched 
image texture for more than 50 years and formed many methods 
of texture features description under different imaging 
conditions. There are several approaches to multispectral 
texture description, both supervised and unsupervised. Haralick 
(1973) presented a new method called gray level co-occurrence 
matrix(GLCM) which is now widely used. He applied GLCM 
to Landsat-1 multispectral image of the California coastal area 
to solve the land use problem. Weszk et al. (1976) researched 
texture for terrain analysis by using first-order statistics of gray 
level differences and second-order gray level statistics. Lopez- 
Espinoza et al. (2008) presented a method for image 
classification which was taken by SPOT-5 and TM, based on 
tree-structured Markov random field (TS-MRF) and a texture 
energy function (TEF). Chellappa et al. (1985) applied 
Gaussian Markov random field (GMRF) models to image 
classification. Pentland (1984) put forward that fractals can be 
used in the area of texture features description. Shu (1998) 
described the SPOT image of Wuhan based on the method of 
fractal assessment in image texture analysis. Chitre and Dhawan 
(1999) used multi band wavelet for natural texture classification. 
People began to research SAR image texture after the first radar 
satellite running in earth orbit launched successfully by 
America. Soh and Tsatsoulis (1999) used GLCM to analyze sea 
ice texture with 100-m ERS-1 synthetic aperture radar (SAR) 
imagery. Duskunovic et al. (2000) detected urban areas with the 
Markov Random Field (MRF) texture classification in SAR 
imagery. Hu et al. (2001) extracted texture information from 
Radarsat imagery of Xuzhou with Daubechies3 orthogonal 
wavelet successfully. Ni et al. (2004) used orthogonal wavelet 
and second generation wavelet for SAR image classification 
and compared the results from different methods with each 
  
  
other. Ivanov and Paschenko (2006) studied SAR image 
segmentation based on fractal dimension field. People also have 
researched infrared imagery texture description recently. Song, 
Wan and Chen (2006) applied GLCM to TM6 infrared imagery 
for image enhancement by computing six textural features. Lin 
et al. (2009) established the detection probability model based 
on texture feature of thermal infrared image with Gabor wavelet. 
All of the above methods of texture features description under 
different imaging conditions can be divided into five categories 
according to the principle proposed (Tuceryan, Jain, 1993). 
They are statistical methods, geometrical methods, structural 
methods, model based methods and signal processing methods. 
Both GLCM and Gabor wavelet are the most popular methods 
among all of them. And this paper will research the 
investigating transformational methods of texture features 
description under different imaging conditions based on Gabor 
wavelet. 
The wavelet theory has been utilized in image texture analysis 
since it was introduced into the area of image process (Mallat, 
1989). And among all branches developed from wavelet, Gabor 
wavelet has been proved to be the optical filter of both spatial 
domain and frequency domain under 2D uncertainty. Dunn, 
Higgins and Wakeley (1994) devised a more rigorous method 
for designing 2D Gabor filters and utilized it to segment images. 
Wu et al. (2001) designed a optimal Gabor filter for Bi-textured 
image segmentation with the Fourier power spectrum density. 
Chen and Wang (2007) integrated Gabor wavelet and 
independent component analysis (ICP) for image classification. 
Clausi and Jernigan (2000) used Gabor filters to classify a SAR 
aerial image and obtain textures from the Brodatz album based 
on human visual system (HVS). Arivazhagan et al. (2006) 
proposed a method of image classification using Gabor filter 
based on rotation invariant features. Also Gabor wavelet has 
been utilized in other areas. Lin et al. (2007) evaluated the 
result of camouflage with Gabor wavelet. Song, Liu and Xie
