【摘要】：數(shù)字電影中圖像具有動(dòng)態(tài)性和幀分布隨機(jī)性,導(dǎo)致圖像重構(gòu)的逼真度不好。傳統(tǒng)方法采用小波重構(gòu)方法,受到小波尺度選擇準(zhǔn)確性影響較大。為了改善數(shù)字電影畫(huà)面重構(gòu)的視覺(jué)效果,提出一種基于相鄰幀補(bǔ)償和電子穩(wěn)像技術(shù)的數(shù)字電影產(chǎn)業(yè)中三維圖像重構(gòu)技術(shù)。對(duì)數(shù)字電影的圖像畫(huà)面進(jìn)行像素特征點(diǎn)掃描,對(duì)掃描輸出的特征點(diǎn)采用相鄰幀差補(bǔ)償方法進(jìn)行模板匹配和邊緣輪廓特征提取,提取數(shù)字電影圖像中動(dòng)態(tài)跳頻特征點(diǎn),對(duì)提取的特征點(diǎn)通過(guò)SIFT算法進(jìn)行電子穩(wěn)像處理,提高圖像重構(gòu)的畫(huà)質(zhì)。實(shí)驗(yàn)結(jié)果表明,采用該方法進(jìn)行數(shù)字電影的三維圖像重構(gòu),具有較好的圖像畫(huà)面輸出效果,在3D和4D影像設(shè)計(jì)中具有應(yīng)用前景。
[Abstract]:The image in digital film is dynamic and the frame distribution is random, which leads to poor fidelity of image reconstruction. The traditional wavelet reconstruction method is greatly affected by the accuracy of wavelet scale selection. In order to improve the visual effect of digital film image reconstruction, a 3D image reconstruction technology in digital film industry based on adjacent frame compensation and electronic image stabilization technology is proposed. The pixel feature points of digital movie images are scanned, and the adjacent frame difference compensation method is used to extract the feature points of dynamic frequency hopping in digital movie images, which is based on template matching and edge contour feature extraction. The extracted feature points are processed by sift algorithm to improve the image quality of image reconstruction. The experimental results show that this method has good image output effect and has the application prospect in 3D and 4D image design.
