edge histogram descriptor using matlab code

This is the last kind of histograms I used in my project. The basic idea is to build a histogram with the directions of the gradients of the edges (borders or contours). It is possible to detect edges in an image but it in this we are interest in the detection of the angles. This is possible trough Sobel operators. The next five operators could give an idea of the strength of the gradient in five particular directions .

The convolution against each of this mask produce a matrix of the same size of t ....etc

Abstract

Background

Despite significant progress in imaging technologies, the efficient detection of edges and elongated features in images of intracellular and multicellular structures acquired using light or electron microscopy is a challenging and time consuming task in many laboratories.

Results

We present a novel method, based on the discrete curvelet transform, to extract a directional field from the image that indicates the location and direction of the edges. This directional field is then processed using the non-maximal suppression ....etc

Gaussian Smoothing

Brief Description

The Gaussian smoothing operator is a 2-D convolution operator that is used to blur' images and remove detail and noise. In this sense it is similar to the mean filter, but it uses a different kernel that represents the shape of a Gaussian ( bell-shaped') hump. This kernel has some special properties which are detailed below. ....etc

matlab code for edge preservation index of an image

A common technique for removing noise from images is by blur-
ring them with a weighted mean or a Gaussian filter. Through these
processes noise reduction is achieved, but unfortunately, valuable
information is lost and the details of object boundaries are
deformed. A solution to this problem, especially for document
images, is the use of an edge preserving smoothing technique
(adaptive mean filter) where the amount of blurring for each pixel is
determined after gathering local informa ....etc

EDGE Compact and EDGE Classic Packet Data Performance
Abstract
Even though cellular radio services have been extremely successful in providing untethered voice communications, wireless data services have captured only a limited market share so far. One obstacle for wireless data services is their limited peak bit rates. Existing wireless data rates, up to several tens of kb/s, may be over one order of magnitude short of what is required to make popular applications user-friendly. To accomplish these necessities we go for ....etc
