VisualSEEk: a fully automated content-based image query system

by John R. Smith, Shih-fu Chang , 1996
"... We describe a highly functional prototype system for searching by visual features in an image database. The VisualSEEk system is novel in that the user forms the queries by diagramming spatial arrangements of color regions. The system finds the images that contain the most similar arrangements of ..."

Recognition-by-components: A theory of human image understanding

by Irving Biederman - Psychological Review , 1987
"... The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory, recog ..."

The Functional Color Arrangement for Industrial Safety in Machinery Work Site 2: Focusing on Chroma Value from Top and Bottom

by Park Hyewon, Jang Seonu
"... This research is to study the functional color arrangement of work clothes based on the color chroma value arrangement, which could affect the safety of workers at the site of the mechanical industry. For the study, 5PB hue, indicating a high satisfaction level with proper colors at the site of the ..."

Face Detection In Color Images

by Rein-Lien Hsu, Mohamed Abdel-mottaleb, Anil K. Jain - IEEE Transactions on Pattern Analysis and Machine Intelligence , 2002
"... Human face detection is often the first step in applications such as video surveillance, human computer interface, face recognition, and image database management. We propose a face detection algorithm for color images in the presence of varying lighting conditions as well as complex backgrounds. Ou ..."

Crystal structure of rhodopsin: a G protein-coupled receptor

by Krzysztof Palczewski, Takashi Kumasaka, Tetsuya Hori, Craig A. Behnke, Hiroyuki Motoshima, Brian A. Fox, Isolde Le Trong, David C. Teller, Tetsuji Okada, Ronald E. Stenkamp, Masaki Yamamoto, Masashi Miyano - LeTrong I, Teller DC, Okada T, Stenkamp RE et , 2000
"... Heterotrimeric guanine nucleotideÐbinding protein (G protein)Ðcoupled recep-tors (GPCRs) respond to a variety of different external stimuli and activate G proteins. GPCRs share many structural features, including a bundle of seven transmembrane a helices connected by six loops of varying lengths. We ..."

. We de-termined the structure of rhodopsin from diffraction data extending to 2.8 angstroms resolution. The highly organized structure in the extracellular region, including a conserved disulÞde bridge, forms a basis for the arrangement of the seven-helix transmembrane motif. The ground

Coloring complexes and arrangements

by Patricia Hersh, Swartz - J. Alg. Comb
"... Abstract. Steingrimsson’s coloring complex and Jonsson’s unipolar complex are interpreted in terms of hyperplane arrangements. This viewpoint leads to short proofs that all coloring complexes and a large class of unipolar complexes have convex ear decompositions. These convex ear decompositions impo ..."

Hamiltonicity and Colorings of Arrangement Graphs

by Stefan Felsner, Ferran Hurtado, Marc Noy, Ileana Streinu - In Proc. 11th Symp. Discrete Algorithms , 2000
"... We study connectivity, Hamilton path and Hamilton cycle decomposition, 4-edge and 3-vertex coloring for geometric graphs arising from pseudoline (ane or projective) and pseudocircle (spherical) arrangements. While arrangements as geometric objects are well studied in discrete and computational g ..."

Coloring and guarding arrangements,

by Prosenjit Bose , Jean Cardinal , Sébastien Collette , Ferran Hurtado , Matias Korman , Stefan Langerman , Perouz Taslakian - 28th European Workshop on Computational Geometry (EuroCG), , 2012
"... Abstract Given an arrangement of lines in the plane, what is the minimum number c of colors required to color the lines so that no cell of the arrangement is monochromatic? In this paper we give bounds on the number c, as well as some of its variations. We cast these problems as characterizing the ..."

EDGE COLORED HYPERGRAPHIC ARRANGEMENTS

by Matthew Miller, Max Wakefield , 903
"... Abstract. A subspace arrangement defined by intersections of hyperplanes of the braid arrangement can be encoded by an edge colored hypergraph. It turns out that the characteristic polynomial of this type of subspace arrangement is given by a generalized chromatic polynomial of the associated edge c ..."

Color Indexing with Weak Spatial Constraints

by Markus Stricker, Alexander Dimai, Er Dimai - in Proc. SPIE Storage and Retrieval for Image and Video Databases , 1996
"... To improve the discrimination power of color indexing techniques we encode a minimal amount of spatial information in the index. We propose an approach that lies between uniformly tesselating the images with rectangular regions and relying on fully segmented images. For each image we define 5 partia ..."
