Abstract: |
The local threshold has two obvious shortcomings: when one sub-block nearly belongs to the background or the goal, the histogram is unimodal and very difficult to divide; When the goal is divided in the different sub-block, segmentation result existence massive effect. For this ,the article unifies global threshold iterative algorithm and local threshold segmentation, and proposes the nearest neighbor interpolation threshold. Based on this method of threshold segmentation, using the linear interpolation, proposed the equal interval interpolation threshold, and then through simulation experiments showing two methods’ validity and feasibility.
