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

Hidden Image，中文称为画中有画的艺术；在表现手法上是一们相当新颖且前卫的艺术，其表现风格多种；一般来说，常见手法是将一个或是多个物体以不同型态的方式巧妙的融合在背景当中，观察者在远方观赏整幅画时，并不会觉得特别突兀，而当视觉集中到某一个焦点上时，透过大脑重新组织之后，其隐藏的物体将渐渐浮现出来。本篇论文主要是提供一个完整的流程；根据luminance space区块化后，透过物体本身区块的相互关系，或是物体与背景的相互关系进行Luminance Labeling，并经由Erosion Processing将物体做适当的破坏，最后以贴图方式给予视觉化呈现。相信透过这样的流程，我们将赋予一般普罗大众一套机制去创造出属於自己的Hidden Image。

This chapter starts with the determination of primary sense of under. Then it focuses on how its spatial senses are extended from the central image schema to its transformations by metonymy. Next, this part also focuses on how its metaphorical senses are extended in terms of the central image schema and transformations by metaphor. In these analyses, this thesis summarizes four kinds of relations: the relation of UP-DOWN, the relation of HIGH-LOW, COVERING relation or the relation of IN-OUT and the relation of SOURCE-PATH-GOAL. Lots of metaphorical senses of under are derived from these basic spatial relations. In this thesis, the relations between the senses derived from central image schema and those derived from its transformations are explored at length. The relations between the spatial senses derived from central image schema and transformations and the metaphorical senses derived from them are also explored at length. The above analyses demonstrate that the sense extension of the spatial preposition is motivated by image schema, which also provides the root for metonymic and metaphorical extension. The semantic network of under is diagramed finally.

论文首先确定了under的首要意义；然后集中探讨了它的空间意义如何从中心意象图式，通过转喻形成许多变体，从而得以延伸；接着分析了它的隐喻意义如何从中心意象图式及其变体通过隐喻而得以延伸，在此分析中，本论文总结了四种关系：上—下关系﹑高—低关系﹑覆盖关系或里—外关系和起点—路径—目标关系，under的很多隐喻意义源于这些基本的空间关系；本论文还对源于中心意象图式的空间意义与源于其变体的空间意义的关系进行了详细的剖析；对源于中心意象图式与其变体的空间意义及其延伸的隐喻意义之间的关系，也同样进行了详细的剖析；通过分析论证了，意象图式是空间介词义项扩展的源泉，同时也为转喻和隐喻提供了基础；最后得出under的语义网络。

On the basement of conventional direct fan-beam reconstruction, this paper gives a newly improved algorithm-"fast filtering-backprojection". This method utilizes the symmetrical circle geometry to sample projection data, and reconstructs image on the Polarcoordinate firstly, then translates this reconstructed image onto the cartesian coordinate system with two interpolating operations so that the computer can show the result image on the VGA screen. This algorithm rebates the calculating backprojection greatly, and shortens a few times of reconstructing time than same kinds of means. With the size of image enlarging, the reconstructing time abates with 2 exponent times. In addition, according to the idea of parallel-beam, we rearrange the fan-beams and reconstruct image using parallel-beam method fastly. The rearranging constraint condition is given here.
