  1. 1. Enhancement of Salient Image Regions for Visual Object Detection

    Författare :Keren Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geodesic distance; graph spectral decomposition; video processing; visual attention; color contrast and distribution; propagation; salient region; figure-ground segmentation;

    Sammanfattning : Salient object/region detection aims at finding interesting regions in images and videos, since such regions contain important information and easily attract human attention. The detected regions can be further used for more complicated computer vision applications such as object detection and recognition, image compression, content-based image editing, and image retrieval.

  3. 2. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Författare :Keren Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

  4. 3. Omission de l'article et du pronom sujet dans le français abidjanais

    Författare :Marita Jabet; Franska; []
    Nyckelord :HUMANIORA; HUMANITIES; mass nouns; articles; omission; subject-pronouns; bare nouns; subject-less clauses; Abidjan; Côte d Ivoire; spoken French; multilingualism; sociolinguistic varieties; French markedness; generic reference; African influences; Franska språket; serial-verb constructions; repetition contexts.; French language;

    Sammanfattning : This study examines the omission of the article and of the subject pronoun in the spoken French of Abidjan, economic capital of Côte d'Ivoire. The occurrence of the bare nouns (NSDs for Noms Sans Déterminant) and subject-less tensed verbs (SujNuls for Sujets Nuls) in question is contrary to common use in standard as well as ordinary French.
