基于光学相关探测的水上目标识别研究

提出了改进的Laplace边缘检测算子与对比度拉伸变换相结合的光学相关物面图像处理方法，对水上目标图像进行边缘检测和对比度拉伸，在精确提取目标边缘特征的同时有效地提高了图像对比度。将其应用到实时联合变换相关器中，实验结果表明，滤波后的图像经两次傅里叶变换后输出的相关点亮度明显增强，由此解决了一些复杂背景、低对比度水上目标的识别问题。

Optical Correlation Detection Based Water Target Recognition

We propose an optical correlation object image processing approach of the combination of improved Laplace edge detection operator and contrast stretch transformation.The approach detects edge and stretches contrast for a water target image.It therefore effectively improves image contrast when precisely extracting target edge features.We also apply it to a real-time joint transform correlator.Experimental results show that the filtered image of the output brightness correlation point is remarkably enhanced a...
