In content-based image retrieval, the representation of local properties in an image is one of the most active research issues. This paper introduces a salient region detector based on wavelet transform. The detector can extract the visually meaningful regions on an image and reflect local characteristics. An annular segmentation algorithm based on the distribution of salient regions is designe...

A number of authors have enriched Nash’s original bargaining problem through the introduction of an additional point, which we call a salient point. When the salient point is restricted to lie in the bargaining set, it is interpreted as a reference point, the outcome, perhaps, of a bargain from an earlier period. When restricted to lie outside the bargaining set, it is interpreted as a claim on...

In this paper, we present a novel image retrieval technique based on salient regions that are invariant under viewpoint and illumination variations. The salient regions are detected according to local entropy and scale selection. The detected regions have very high repeatability under various viewpoint and illumination changes. We apply the invariant region detector on content-based image retri...

By successfully exploiting human vulnerabilities, fake websites have emerged as a major source of online fraud. Fake websites continue to inflict exorbitant monetary losses and also have significant ramifications for online security. We explore the process by which salient performance-related elements could increase the reliance on protective tools and, thus, reduce the success rate of fake web...

This paper shows how strings can be used in a natural images classification task. We propose to build an attributed string from a set of regions of interest detected thanks to an interest point detector. These salient zones are characterized by local signatures describing singularities and they are linked by using graph seriation algorithms and perceptual methods. Once each image is represented...

A new salient semantics-less blob detector named the Stable Wave Detector (SWD) is suggested. The detector proved to be particularly very useful in tracking a target in a videosequence. SWD is a multiscale blob detector in the intensity image. The targets are blobs in 2D which correspond to local maxima/minima of the image intensities or positive and negative peaks in 1D. SWD belongs to a group...

Object extraction is an essential branch of the computer vision, concerned with the analysis of images to extract useful information from the world. It covers wide range of image processing fields and plays an important role in computer vision. In this dissertation, contour detection is mainly discussed to realize object extraction, realized in three steps: edge detection, contour segment detec...
