Accurate Detection Of Edge Orientation For Color And
"... Frequency domain properties of an image are used for precise detection of edge orientation in color and multi-spectral imagery. The orientation estimation is established as a minimization problem, formulated as a tensor method, and simplified by solving its dual in terms of spatial partial derivativ ..."

On edge orienting methods for graph coloring
, 2006
"... We consider the problem of orienting the edges of a graph so that the length of a longest path in the resulting digraph is minimum. As shown by Gallai, Roy and Vitaver, this edge orienting problem is equivalent to finding the chromatic number of a graph. We study various properties of edge orienting ..."

Edge-Oriented Uniform Intra Prediction
"... Abstract—We propose an intra prediction solution to block-based image compression. In order to adapt to local image features during intra prediction, we consider the distinct image singularities within the model of piece-wise smooth functions. With such singularities, i.e., edges in this paper, intr ..."

, intra prediction can be performed by solving Laplace equations. Moreover, since edges exhibit spatial correlations, we design a rate-distortion optimized method for edge extraction and edge coding. Our edge-oriented intra prediction thus consists of the prediction of smooth regions as well
Fast Edge Orientation for Unweighted Graphs
"... Abstract We consider an unweighted undirected graph with n vertices, m edges, and edge connectivity 2k. The weak edge orientation problem requires that the edges of this graph be oriented so the resulting directed graph is at least k edge-connected. Nash-Williams proved the existence of such orient ..."

Histograms of Oriented Gradients for Human Detection
- In CVPR
, 2005
"... We study the question of feature sets for robust visual object recognition, adopting linear SVM based human detection as a test case. After reviewing existing edge and gradient based descriptors, we show experimentally that grids of Histograms of Oriented Gradient (HOG) descriptors significantly out ..."

The "Independent Components" of Natural Scenes are Edge Filters

It has previously been suggested that neurons with line and edge selectivities found in primary visual cortex of cats and monkeys form a sparse, distributed representation of natural scenes, and it has been reasoned that such responses should emerge from an unsupervised learning algorithm that attem ..."

Edge Orientation-based Fuzzy Hough Transform (EOFHT)
- CONFERENCE OF THE EUROPEAN SOCIETY FOR FUZZY LOGIC AND TECHNOLOGY
, 2003
"... The Hough Transform [6]-HT- is a standard tool in image analysis that allows recognizing global patterns in an image space. To detect shapes in noisy data, preserving the idea of the conventional HT, but allowing detection of approximate shapes, the Fuzzy Hough Transform-FHTwas introduced [8]. Based ..."

]. Based on the FHT way of work, we propose an Edge Orientation-based Fuzzy Hough Transform-EOFHT- wherein the information provided by the gradient vector is considered. The use of gradient vector's stability properties allows considering only some relevant orientations, so reducing the computational
