Image convolution works in the same way as one-dimensional convolution. For instance, images can be viewed as a summation of impulses, i.e., scaled and shifted delta functions.Likewise, linear systems are characterized by how they respond to impulses; that is, by their impulse responses.As you should expect, the output image from a system is equal to the input image convolved with the system's Chapter 24- Linear Image Processing 399 a.

    processing speed of image information [3].The maximum resolution is achievable which is in digital image processing limited by the density of pixels. It is possible to implement optical image processing even in the case of relatively low beam intensity using the high non linearity of the Photo Refractive effect. 2.2 Digital Image Processing magnification are the available image processing methods that may enhance the image quality in digital imaging [13,14]. Likewise, Moystad et al. [15] reported that PSP images that were enhanced with these methods improved the decision of and fissures, cervical burnout, mach band effect, and dental

In recent years, the technologies related to image, video and sound have found their own importance towards better visualization tools.

    Mach Band Effect • Where there is a sharply defined difference in density such as the dento-enamel junction, the dentin may appear more radiolucent as the DEJ is approached. • This can contribute to a false positive reading and unnecessary restoration of sound tooth structure.

Image will have high contrast, if the dynamic range is high, and image will have dull washed out gray look if the dynamic range is low. 1.5. Define Mach band effect. The spatial interaction of Luminance from an object and its surround creates a phenomenon called the mach band effect. 1.6. Define Brightness.
