摘　　要：灰度投影算法是车载视频稳定当中应用较多的运动估计算法,然而投影法对图像的对比度有较高要求,而且在恶劣天气情况下,针对直方图均衡化进行对比度增强效果不好,为此提出采用小波边缘增强的方法对图像进行预处理。实验表明,该方法有效地提高了灰度投影算法在低对比度图像上的运动矢量估计精度。Gray projection is a hot motion estimate algorithm for on-board video of stabilization,but it requires the image to have a high image contrast.And in the case of bad weather,the histogram equalization is not good at image contrast enhancement,so the method for edge enhancement of wavelet is proposed to achieve pretreatment.Experiment of the algorithm demonstrates that the algorithm improves the gray projection＇s motion estimate accuracy for the degraded images.
