摘要
为了实现在复杂光场条件下获取的图像中特定区域的自动识别，用对局部灰度变化敏感的零交叉检测器检测零交叉点，然后利用零交叉点插值而求出的动态阈值曲面对图像进行二值化，最后通过对区域特征的提取和分类准则的确定，准确识别出目标区域，从而克服了复杂光场对图像识别结果所带来的影响。
It is required to indentify some regions in images obtained in condition of nonuniform illumination.Zero-crossing detector is sensitive to the local varity of gray level,and a threshold surface to segment image can be obtained by interpolating the zero-crossing points.Then the destination region can be detected using the method of pattern recognition.It can be seen that the method advoids the influence of nonuniform illumination effectively.
