摘要

This proposal focuses on operation of the RIT Digital and Remote Sensing Lab'ssynthetic image generation (DIRSIG) software model within the 0.4 to 1.0 micrometer wavelength region. The approach to this study is two-fold. First, an improved method is established for modeling reflectivity effects. This will include generating the associated reflectivity database. Currently, DIRSIG permits only ideal specular or ideal diffuse behavior. In a real scene, most objects actually exhibit some mixture of specular and diffuse behavior. The proposed treatment will essentially separate the reflectance characteristics into specular and diffuse components which vary as a function of view angle. Second, the performance of DIRSIG in the visible region using the improved technique must be evaluated. This will be accomplished by collecting truth data from an actual scene and comparing it to data from a synthetically generated image of the same scene. This evaluation will also serve as a first overall assessment of the model's performance in this wavelength region.
