First, urban landscapes are composed of complex features. Second, traditional classifiers employ spectral information based on single pixel value and ignore a great amount of spatial information. Texture plays an important role in image segmentation and object recognition, as well as in interpretation of images in a variety of applications. This study analyzes urban texture features in multi-spectral image data. Recent developments in the very powerful mathematical theory of wavelet transforms have received overwhelming attention by image analysts. An evaluation of the ability of wavelet transform in urban feature extraction and classification was performed in this study, with six types of urban land cover features classified. The preliminary results of this research indicate that the accuracy of texture analysis in classifying urban features in fine resolution image data could be significantly improved with the use of wavelet transform approach.

[Termes IGN] superposition d'imagesRésumé : (Auteur) The goal of this research was to explore the utility of very high spatial resolution, digital remotely sensed imagery for monitoring land-cover changes in habitat preserves within southern California coastal shrublands. Changes were assessed for Los Penasquitos Canyon Preserve, a large open space in San Diego County, over the 1996 to 1999 period for which imagery was available. Multispectral, digital camera imagery from two summer dates, three years apart, was acquired using the Airborne Data Acquisition and Registration (ADAR) digital-camera system. These very high resolution (VHR) image data (1 m), composed of three visible and one near-infrared wavebands (V/NIR), were the primary image input for assessing land cover change. Image-derived datasets generated from georeferenced and registered ADAR imagery included multitemporal overlays and multitemporal band differencing with threshold selection. Two different multitemporal image classifications were generated from these datasets and compared. Single-date imagery was analyzed interactively with image-derived datasets and with information from field observations in an effort to discern change types. A ground sampling survey conducted soon after the 1999 image acquisition provided concurrent ground reference data. Most changes occurring within the three-year interval were associated with transitional phenological states and differential precipitation effects on herbaceous cover. Variations in air temperatures and timing of rainfall contributed to differences that the seven-week image acquisition offset may have caused. Disturbance factors of mechanical clearing, erosion, potentially invasive plants, andfire were evident and their influence on the presence, absence, and type of vegetation cover were likely sources of change signals. The multitemporal VHR, V/NIR image data enabled relatively fine-scale land cover changes to be detected and identified. Band differencing followed by mutlitemporal classification provided an effective means for detecting vegetation increase or decrease. Detailed information on short term disturbance effects and long-term vegetation type conversions can be extracted if image acquisitions are carefully planned and geometric and radiometric processing steps are implemented.

[Termes IGN] visualisation 3DRésumé : (Auteur) The automation of feature extraction from digital imagery is the most challenging task facing those working today in photogrammetry research and development. Unsolved so far is the fully automatic and reliable detection and reconstruction of objects. There are solutions available for the automation of specific tasks under certain restrictions, but all methods show deficiencies when faced with poor image quality. Occlusions and shadows are factors which frequently prevent high success rates. One current practice involves a semiautomatic approach, a human operator being employed for the extremely difficult interpretation tasks. The authors present an overview of inJECT, a semiautomatic building extraction system. This system, developed by INPHO in cooperation with the Institute of Photogrammetry at the University of Bonn, offers a set of building primitives covering the most common basic house shapes. Automated modules assist the human operator in the measuring phase. The system does not require stereo viewing and operators need only a short course of training.
