Abstract:
Remote-sensed imagery acquired from satellites or aircraft continues to offer passive, low-cost, and broad-field monitoring of Earth's surface and has enabled a new suite of consumer-oriented applications such as Google Earth. Advances in sensing technology are producing images with increasing spatial resolution, which means that individual pixels are more likely to represent the spectral reflectance of regions composed of single rather than mixes of materials. The problem of determining the composition of the regions imaged by single pixels through spectral un-mixing is giving way to the problem of characterizing the spatial arrangement of the pixels. Such characterizations can help distinguish land-cover classes consisting of similar materials but in different spatial configurations.

In this context, I will present my work on analyzing spatial relationships in remote-sensed imagery. I will discuss the application of a homogeneous image texture descriptor to performing content-based similarity retrieval in large collections of high-resolution satellite imagery. This serves as motivation for my subsequent work on using image texture for a number of classification tasks in remote-sensed imagery.
