以演化概念置入與影片互動之虛擬內容

隨著多媒體數位內容的分析趨於成熟，有效的置入虛擬內容已經被廣泛地研究，並使用在影片上來傳達廣告意象，以及加強影片內容所能呈現的資訊；然而，如何在降低干擾程度的前提下，將虛擬內容以具有吸引力的方式置入於影片中仍然是一個重要並有挑戰性的問題。在這篇論文中，我們提出了一個創新的虛擬內容置入系統，能夠讓虛擬內容根據我們從演化生物學概念上所定義出來的行為來進行生動的演化。對於影片而言，不僅是虛擬內容傳達資訊的載體，更提供了一個環境讓虛擬內容能夠以生命般的形式存活其中，也使得虛擬內容可以透過演化機制和影片內容產生互動。此外，我們將演化的過程分為三個相依的階段，虛擬內容會隨著互動次數的增加，演化出不同的外觀和行為。藉由這種方式，我們所提出來的系統建構了虛擬內容和影片內容在視覺上的關聯性，並達到降低干擾程度的目的，同時也提高了影片觀賞者對虛擬內容置入的吸引力和接受度。由實驗結果得知，以我們系統的方式置入虛擬內容所產生的影片有效的降低了虛擬內容置入所帶來的干擾，並提升了觀看者對被置入的虛擬內容的印象和認知，而虛擬內容的演化過程也增進了觀眾對於原本影片的觀感，並吸引他們享受這個娛樂性的故事情節。

With the development of multimedia analysis, virtual content insertion has been widely used and studied for the video enrichment and advertising. However, how to less-intrusively insert a virtual content into general videos with an attractive representation is a significant and challenging problem in the field of virtual content insertion. In this paper, we present a novel virtual content insertion system which inserts virtual contents into videos with evolved animations according to predefined behaviors based on the concept of evolutionary biology. The videos are considered as not only carriers of message conveyed by the virtual content but also the environment in which the lifelike virtual contents live. Thus, the inserted virtual content interacts with video contents and triggers the artificial evolution. The evolution process is divided into distinct yet dependent phases, in which the virtual content evolves its appearances and behaviors with the incremental interactions. In this way, the proposed system constructs a visually relevant connection between the inserted virtual content and the source videos to reduce the intrusiveness and increase the acceptability and the attractiveness simultaneously. User studies show that the augmented videos produced by the proposed system effectively reduce the intrusiveness, and emphasize the impression of the inserted virtual content. Moreover, the evolution process improves the audience’s viewing experience to the original video content and engages viewers with the entertaining storyline.
