Book excerpt: Master's Thesis from the year 2018 in the subject Computer Science - Applied, grade: 1,0, RWTH Aachen University (Visual Computing Institute), language: English, abstract: The goal of this thesis is to provide a texture generation approach that works on cellular textures and enables structural modifications when generating a new output exemplar. In the field of computer graphics, two-dimensional textures are an efficient tool to make a virtual scene richer in detail and therefore visually more appealing. Consequently, the perceived quality of a rendered image highly depends on the quality of the used textures. Unfortunately, creating textures by hand is a time-consuming task, which in extreme cases can only be performed by professional artists. On the other hand, the use of real photographs often requires post-processing steps, e.g. to make them tileable so that there are no visual transitions between multiple texture copies covering a large surface. Approaches exist that automatically create new texture variants with different sizes based on a given input sample. However, most of these methods focus on generating output textures that are as similar to the original input as possible, while not allowing for further modifications.

Available in PDF, EPUB and Kindle. Book excerpt: Computer methods are presented which deal with the problems of visual texture, specifically Texture Analysis and Texture Synthesis. The Decision Theory Method, as its name indicates, is based on the principles of statistical decision theory. This method in conjunction with the Internal Covering Theory, automatically generates a set of interval complexes which act as 2-D filters that detect texture features in the scene of analysis. The versatility of this method to deal with various problems of visual texture, such as scene segmentation using textural information, extraction of texture borders, discrimination/recognition of both spatially and chromatically textured scenes, etc. is demonstrated. A model is proposed that views the pixels of a digitized textural scene as a two- way seasonal time series. Based on this model, a method is developed for synthesis of natural looking textures. This method possesses a desirable quality that the parameters needed for the synthesis are derived from the analysis of parent'' texture, i.e., the texture to be imitated. Extending the concepts of two-dimensional formal grammars, known as array grammars, multilevel array grammars'' are introduced. These are shown capable of generating complex texture scenes, specifically brickwall-type'' texture, that is, those textures which are perceived at many levels and at each level, they can be either structural or statistical. A way of specifying these grammars for texture scenes in real cases, with the help of interval complexes, '' is also indicated. (96 references) (auth).

Available in PDF, EPUB and Kindle. Book excerpt: Discover an enhanced synthetic approach to developing and screening chemical compound libraries Diversity-oriented synthesis is a new paradigm for developing large collections of structurally diverse small molecules as probes to investigate biological pathways. This book presents the most effective methods in diversity-oriented synthesis for creating small molecule collections. It offers tested and proven strategies for developing diversity-oriented synthetic libraries and screening methods for identifying ligands. Lastly, it explores some promising new applications based on diversity-oriented synthesis that have the potential to dramatically advance studies in drug discovery and chemical biology. Diversity-Oriented Synthesis begins with an introductory chapter that explores the basics, including a discussion of the relationship between diversity-oriented synthesis and classic combinatorial chemistry. Divided into four parts, the book: Offers key chemical methods for the generation of small molecules using diversity-oriented principles, including peptidomimetics and macrocycles Expands on the concept of diversity-oriented synthesis by describing chemical libraries Provides modern approaches to screening diversity-oriented synthetic libraries, including high-throughput and high-content screening, small molecule microarrays, and smart screening assays Presents the applications of diversity-oriented synthetic libraries and small molecules in drug discovery and chemical biology, reporting the results of key studies and forecasting the role of diversity-oriented synthesis in future biomedical research This book has been written and edited by leading international experts in organic synthesis and its applications. Their contributions are based on a thorough review of the current literature as well as their own firsthand experience developing synthetic methods and applications. Clearly written and extensively referenced, Diversity-Oriented Synthesis introduces novices to this highly promising field of research and serves as a springboard for experts to advance their own research studies and develop new applications.

Book excerpt: Image Modeling compiles papers presented at a workshop on image modeling in Rosemont, Illinois on August 6-7, 1979. This book discusses the mosaic models for textures, image segmentation as an estimation problem, and comparative analysis of line-drawing modeling schemes. The statistical models for the image restoration problem, use of Markov random fields as models of texture, and mathematical models of graphics are also elaborated. This text likewise covers the univariate and multivariate random field models for images, stochastic image models generated by random tessellations of the plane, and long crested wave models. Other topics include the Boolean model and random sets, structural basis for image description, and structure in co-occurrence matrices for texture analysis. This publication is useful to specialists and professionals working in the field of image processing.
