    • Hidden Image，中文稱為畫中有畫的藝術；在表現手法上是一們相當新穎且前衛的藝術，其表現風格多種；一般來說，常見手法是將一個或是多個物體以不同型態的方式巧妙的融合在背景當中，觀察者在遠方觀賞整幅畫時，並不會覺得特別突兀，而當視覺集中到某一個焦點上時，透過大腦重新組織之後，其隱藏的物體將漸漸浮現出來。

    本篇論文主要是提供一個完整的流程；根據luminance space區塊化後，透過物體本身區塊的相互關係，或是物體與背景的相互關係進行Luminance Labeling，並經由Erosion Processing將物體做適當的破壞，最後以貼圖方式給予視覺化呈現。相信透過這樣的流程，我們將賦予一般普羅大眾一套機制去創造出屬於自己的Hidden Image。

    Hidden Image is an image contains one or more embedded figures. The hidden figure merges into typically a busy image such that it does not standout and remains unnoticeable for a while. It takes the viewer to focus or some targeted effort to detect the hidden figure and might requires some hint to be able to do so.

    In this paper, we provide the technological processes to create the hidden image which normal Texture Synthesis can’t be done; According to quantization of background and figure, we manage to recolor the quantized color of figure through Luminance Labeling Processing which is base on relationship between background and figure, we also manage to remove some parts assigned by user to make our result more natural but can still recognize the figure. Finally, we present the result using the Texture Processing. We believe the proposed system can provide a user-friendly tool to create their own Hidden Image.
