When computing an approximation to the gradient, it is critical that the x and y partial derivatives be computed at exactly the same position in space However, using the above approximations, Gx is actually the approximation to the gradient at the interpolated point [i,j + ~] and Gy at [i + ~,j] For this reason, 2 x 2 first differences, rather than 2 x 1 and 1 x 2 masks, are often used for the x and y partial derivatives: (59)

Now, the positions about which the gradients in the x and y directions are calculated are the same This point lies between all four pixels in the 2 x 2 neighborhood at the interpolated point [i + ~,j + ~] This fact may lead to some confusion Therefore, an alternative approach is to use a 3 x 3 neighborhood and calculate the gradient about the center pixel These methods are discussed in Section 52

Algorithms for edge detection contain three steps: Filtering: Since gradient computation based on intensity values of only two points are susceptible to noise and other vagaries in discrete computations, filtering is commonly used to improve the performance of an edge detector with respect to noise However, there is a trade-off between edge strength and noise reduction More filtering to reduce noise results in a loss of edge strength

Enhancement: In order to facilitate the detection of edges, it is essential to determine changes in intensity in the neighborhood of a point Enhancement emphasizes pixels where there is a significant change in local intensity values and is usually performed by computing the gradient magnitude Detection: We only want points with strong edge content However, many points in an image have a nonzero value for the gradient, and not all of these points are edges for a particular application Therefore, some method should be used to determine which points are edge points Frequently, thresholding provides the criterion used for detection Examples at the end of this section will clearly illustrate each of these steps using various edge detectors Many edge detection algorithms include a fourth step: Localization: The location of the edge can be estimated with subpixel resolution if required for the application The edge orientation can also be estimated It is important to note that detection merely indicates that an edge is present near a pixel in an image, but does not necessarily provide an accurate estimate of edge location or orientation The errors in edge detection are errors of misclassification: false edges and missing edges The errors in edge estimation are modeled by probability distributions for the location and orientation estimates We distinguish between edge detection and estimation because these steps are performed by different calculations and have different error models Many edge detectors have been developed in the last two decades Here we will discuss some commonly used edge detectors As will be clear, edge detectors differ in use of the computational approach in one or more of the above three steps We will discuss the implications of these steps after we have discussed the edge detectors
