Example text

The edge locations would therefore be shifted by one half of a pixel in the −x and −y directions. 5) This operator is symmetrical with respect to the pixel (x,y), although it does not consider the value of the pixel at (x,y). Whichever operator is used to compute the gradient, the resulting vector contains information about how strong the edge is at that pixel and what its direction is. The magnitude of the gradient vector is the length of the hypotenuse of the right triangle having sides and this reflects the strength of the edge, or edge response, at any given pixel.

Com/wiki. Otsu, N, ‘‘A Threshold Selection Method from Grey-Level Histograms,’’ SMC 9, no. 1 (1979): 62–66. Parker, J. R. Practical Computer Vision Using C. , 1994. 1 The Purpose of Edge Detection Edge detection is one of the most commonly used operations in image analysis, and there are probably more algorithms in the literature for enhancing and detecting edges than any other single subject. The reason for this is that edges form the outline of an object, in the generic sense. Objects are subjects of interest in image analysis and vision systems.

A second parameter can be used to change the default return image. The call img = cvLoadImage (filename, f); Chapter 1 ■ Practical Aspects of a Vision System returns a 1 channel (1 byte per pixel) grey-level image if f=0, and returns the actual image type that is found in the file if f<0. Writing an image to a file can be simple or complex, depending on what the user wants to accomplish. Writing grey-level or RGB color images is simple, using the code: k = cvSaveImage( filename, img ); The filename is, as usual, a string indicating the name of the file to be saved, and the img variable is the image to be written to that file.
