In this thesis, several problems of time-dependent systems in various branches of physics are investigated by making use of the generalized invariant theory and the invariant-related unitary transformation formulation. The problems are given as follows:(1) Spin model and geometric phase factor in the fiber We investigate the fiber experiment performed by Chiao-Tomita and the Chiao-Wu theory concerning the geometric phase factor in the optical fiber, and then show that the investigation of the propagation of photons inside the noncoplanar optical fiber can be regarded as that of a second-quantization spin model.

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。
