Detecting Edges in Noisy Face Database Images
In this paper, a morphological-based system for detecting edges in reallife images is presented. The corner stone for this system is the hit-miss transform, which provides good performance in reallife images under noise conditions. The classical implementation of this transform suffers from drawbacks that are tackled in this paper. The new modified hit-miss transform is introduced to provide be...
متن کاملDetecting Faint Curved Edges in Noisy Images
A fundamental question for edge detection is how faint an edge can be and still be detected. In this paper we offer a formalism to study this question and subsequently introduce a hierarchical edge detection algorithm designed to detect faint curved edges in noisy images. In our formalism we view edge detection as a search in a space of feasible curves, and derive expressions to characterize th...
متن کاملDetecting Regions from Single Scale Edges
We believe that the potential of edges in local feature detection has not been fully exploited and therefore propose a detector that starts from single scale edges and produces reliable and interpretable blob-like regions and groups of regions of arbitrary shape. The detector is based on merging local maxima of the distance transform guided by the gradient strength of the surrounding edges. Rep...
متن کاملDetecting Edges from Non-uniform Fourier Data Using Fourier Frames
Edge detection plays an important role in identifying regions of interest in an underlying signal or image. In some applications, such as magnetic resonance imaging (MRI) or synthetic aperture radar (SAR), data are sampled in the Fourier domain. Many algorithms have been developed to efficiently extract edges of images when uniform Fourier data are acquired. However, in cases where the data are...
متن کاملAn Integral Criterion for Detecting Boundary Edges and Textured Regions
Edge maps which are computed from textured scenes using existing methods based on local image analysis are not very meaningful. This is because edges at object boundaries are not differentiated from edges in texture. We introduce a real-time algorithm that overcomes this difficulty by computing the Direchlet integral in a small image patch at different scales. These measurements are combined an...
