The defocus of imaging can be modeled as a heat diffusion process and represented mathematically by a diffusion equation, where the image blur is corresponded to the diffusion of heat. To improve the quality of observed images, we propose an algorithm of multi-focus image fusion based on the depth extraction. The optical imaging of two multi-focus images is simulated by the heat equations of positive...
This paper presents an adaptive fusion method used in heterogeneous sensor networks, which consist of infrared sensors and visible sensors. A fuzzy system is applied to classify the imaging illumination conditions. We select three image quality evaluation parameters as the inputs of the fuzzy system, and the system’s output will determine the fusion weights of the two kinds of images. It means that...
