自动目标检测是图像精确制导技术的重要研究内容。针对地面复杂背景条件下目标难以检测的问题,提出一种结合灰度形态学滤波与直方图独立蜂搜索的目标分割方法。首先,对复杂背景下的图像进行形态学滤波和增强,增强目标和背景的灰度对比度;然后利用文中提出的图像直方图独立峰搜索方法确定图像阈值.对图像进行分割。实验表明:文中方法是有效的.对复杂背景下的目标图像可取得较好的分割效果。
Automatic target detection is an important part of the research on imaging precision guided technology. Since it is difficult to recognize targets in a complex background, a segmentation algorithm based on gray-scale morphology filter and searching independent hump of the image histogram has been proposed. Firstly , morphology methods had been used to filtering the image noise and enhance the gray scale contrast between the object and the background;and then determine the histogram threshold by searching independent hump of the image histogram. The new approach is proved to be feasible and effective by some comparative experiments.
