摘　　要：舰船尾迹是确定其运动方向的依据,在对其识别与跟随时,由于受多种因素的干扰,使得图像质量较差。为了令舰船三维动画的渲染效果更加逼真,研究舰船尾迹特效动画关键帧图像智能增强算法。利用颜色平衡算法对舰船尾迹特效动画关键帧图像实施仿射变换处理,平衡图像各颜色通道的灰度分布值;根据形态成分分析方法,将图像分离为结构图与纹理图;采用多尺度变换方法确定结构图与纹理图的低频系数与高频系数,并对其融合处理;通过多尺度反变换方法实现关键帧图像的智能增强。实验结果表明,该算法可以缓解关键帧图像细节信息丢失、颜色失真等问题,增强后图像的峰值信噪比提升幅度明显。The ship wake is the basis for determining the motion direction of ships.When recognizing and following the ship wake,its image quality is poor due to the interference of various factors.Therefore,an intelligent enhancement algorithm for key frame image of ship wake special effect animation is studied to make the rendering effect of ship 3D animation more realistic.The color balance algorithm is used to carry out affine transformation on the key frame image of the ship wake special effect animation,and balance the gray distribution value of each color channel of the image.The image is separated into structure map and texture map by the means of morphological component analysis.The low frequency coefficients and high frequency coefficients of the structure images and texture images are determined by multi⁃scale transformation method,which are fused then.The intelligent enhancement of the key frame image is realized by multi⁃scale inverse transformation method.The experimental results show that the algorithm can alleviate the loss of detail information and color distortion of the key frame image,and the peak signal⁃to⁃noise ratio(PSNR)of the enhanced image is improved significantly.
