  • 摘要: 為了預(yù)測(cè)雙目立體圖像內(nèi)容對(duì)視覺健康可能產(chǎn)生的危害,該文提出一種基于場(chǎng)景模式的立體圖像舒適度客觀評(píng)價(jià)模型。根據(jù)場(chǎng)景中前景目標(biāo)和后景區(qū)域相對(duì)于顯示屏幕的凹凸性以及是否處于舒適觀看區(qū),將自然場(chǎng)景抽象為多種場(chǎng)景模式。在模式選擇階段,從視差圖中自適應(yīng)分割出前景目標(biāo)和后景區(qū)域,根據(jù)前、后景的視差角特征確定場(chǎng)景所屬的模式;在建模階段,采用前、后景的視差角特征結(jié)合前景的寬度角和曲折度特征對(duì)各個(gè)場(chǎng)景模式分別進(jìn)行建模,并量化了前、后景視差因素對(duì)視覺舒適度的影響。在IVY數(shù)據(jù)庫上的實(shí)驗(yàn)結(jié)果表明,所提出的模型與主觀感知存在較好的一致性,Pearson相關(guān)系數(shù)高于0.91, Spearman相關(guān)系數(shù)高于0.90, Kendall相關(guān)系數(shù)高于0.74,平均絕對(duì)值誤差低于0.24,均方根誤差低于0.32,與現(xiàn)有的方法相比,該文所提出的模型的評(píng)價(jià)效果更好,更接近于主觀測(cè)試結(jié)果。
