摘要
在多帧影视特效图像视觉传达过程中,由于提取的图像特征差异,使得视觉传达效果较差。提出三维激光扫描的多帧影视特效图像视觉传达方法研究。依托于三维激光扫描技术,采集多帧影视特效图像。针对图像中包含的噪音,通过小波分析的方法进行处理,并将图像中包含的目标特征提取出来。图像特征数据在极限学习机模型的作用下进行过滤处理,为后续视觉传达提供基础。基于粒子群完成多帧影视特效图像视觉传达。采用基于层次分析和基于红外光谱的视觉传达方法,同文中设计方法进行视觉传达测试,实验结果表明:文中设计方法将图像传达成功率分别提升了31.48%、16.55%,实现了图像视觉传达效果的提升。
In the visual communication process of multi frame film and television special effects image,the visual communication effect is poor due to the difference of image features. Therefore,the visual communication method of 3D laser scanning multi frame special effects image is proposed. Relying on the 3D laser scanning technology,we can collect multiple frames of special effects images. In view of the noise contained in the image,the wavelet analysis method is used to process,and the features of the processed image are extracted. The feature extraction of image data is normalized to provide the basis for subsequent visual communication. Finally,based on particle swarm optimization,the visual communication of multi frame special effects image is completed. Using the visual communication method based on AHP and infrared spectrum,the visual communication test is carried out with the design method in this paper. The experimental results show that the design method in this paper improves the image clarity by 31. 48% and 16. 55% respectively,greatly improving the image visual communication effect.
