Image segmentation is the key step for image processing to image analysis. In order to deal with the
difficulties in automatic selection and the vast computation of multi- threshold image segmentation,a
multi-threshold segmentation algorithm based on Ant Colony is proposed. Compared with traditional multi-threshold segmentation algorithm, the proposed algorithm has better segmentation result and
decreases the computation greatly. The experimental results demonstrate that the algorithm given in this paper can cope with multil-threshold image segmentation efficiently and rapidly.
In this paper, the spectral reflectance which ranges from 780nm to 1100nm for some typical targets is measured by using spectroradiometer. After the reflection properties analyzing, a near infrared (NIR) scene simulation method based on reflection properties of the typical target is presented. The experiment result shows the global features of NIR scene and laid the foundation of NIR scene simulation in future.
