摘　　要：全息激光投影退化图像包含噪声、光照不均匀等多种因素,为了优化图像质量,提高图像清晰度,提出全息激光投影退化图像相位恢复技术。首先,采用小波阈值方法去除含噪的全息激光投影退化图像中的噪声;其次,结合Retinex算法与高斯低通滤波器估计全息激光投影退化图像的入射分量,采用分区的局部色条映射算法结合入射分量增强全息激光投影退化图像;最后,基于卡通-纹理模型的相位恢复方法展开退化图像修复,实现全息激光投影退化图像修复。实验结果表明,所提方法图像具有较好的去噪效果和增强效果,同时,相位恢复精度高于97.0%,SSIM值达到0.9,MSE值低于0.9%,峰值信噪比高于7.14 dB,具有较优的全息激光投影退化图像相位恢复效果。Holographic laser projection degraded images contain various factors such as noise and uneven illumination.In order to optimize image quality and improve image clarity,a holographic laser projection degraded image phase recovery technology is proposed.Firstly,the wavelet threshold method is used to remove noise from degraded holographic laser projection images containing noise;Secondly,combining the Retinex algorithm with a Gaussian low-pass filter to estimate the incident component of the holographic laser projection degraded image,using a partitioned local color strip mapping algorithm combined with the incident component to enhance the holographic laser projection degraded image;Finally,the phase restoration method based on the cartoon texture model is used to repair degraded images and achieve holographic laser projection for image restoration.The experimental results show that the proposed method has good denoising and enhancement effects on the image.At the same time,the phase recovery accuracy is higher than 97.0%,and the SSIM value reaches 0.9,the MSE value is lower than 0.9%,and the peak signal-tonoise ratio is higher than 7.14 dB.It has a better phase recovery effect on holographic laser projection degraded images.
