Abstract

Texture is of vital importance when rendering realistic infrared images. Traditional attempts to simulate infrared textures often suffer from insufficient realism seen in actual infrared images. This paper presents a synthesis model for generating infrared texture of aeolian sand ripples. By integration of physical radiation model and texture structure model, sources of variability that causes IR texture are modeled. The physical radiation model takes into account geometrical, thermodynamic and meteorological parameters and calculates the thermal radiation distribution of different surface slopes. The texture structure model is introduced based on natural landscape features to simulate spatial distribution patterns of aeolian sand ripples. Simulation results are indicative of good performance of the proposed method to simulate radiometrically-correct yet visually-appealing infrared textures.
