摘要
提出一种针对复杂场景的基于图像边缘强度的阈值分割算法。首先进行边缘检测,然后根据边缘强度进行像素灰度值加权平均计算出图像的分割阈值。该算法简单、实用,可对海上及空中目标进行准确分割,并已在实际的跟踪系统中进行了应用,结果表明目标分割正确,系统实时性强、稳定可靠。
A thresholding segmentation algorithm for complex background is introduced. The method is based on edge detecting of infrared image. Firstly, the image edge is detected, and then segmentation threshold is computed by weighting and averaging value of pixels gray. The method is simple and practical, and it can segment the targets in the air and on the sea exactly. And it has been used in tracking system, the experimental result indicates that the algorithm is correct and real-time, and the system is reliable.
