Texture Synthesis Code for Cold Backgrounds

摘要

It is not an easy task to develop an approach to synthetic image generation which is both physically based and yet universal, because these are somewhat contradictory requirements to the extent that the physics of scattering off snow for a particular scene depends on the specifics of the scene. Our goal in Phase I was to extract universal physical features of all such scenarios while confining attention to coherent microwave scattering. The work was intended to provide a foundation upon which more sophisticated physical models could be used to generate the physical parameters needed to drive texture simulation, as these models become available. In Phase II we propose significant new work which includes: (1) extension of the background models; (2) further development of the capability to model mmw emission, visible scattering and IR emission; (3) application of current texture generation procedures to the extended bands and background types; (4) enhancement of texture synthesis capabilities along with validation; and (5) the development of a user-friendly interface for editing inputs to the physical models, running the background and scattering/emission models and displaying the synthetic texture.
