Translation property results in a phase shift of the spectrum. (a) Original
image. (b) The magnitude of the Fourier spectrum from (a) represented as an
image. (c) The phase of the Fourier spectrum from (a) represented by an image.
(d) and (g) are original image shifted by 128 rows and 128 columns, and 64 rows
and 64 columns, respectively. (e), (h) The magnitude spectrum. (f), (i) Phase
spectrum. These images illustrate that when an image [...]
[...] operator is a discrete
differentiation operator, calculating an approximation of the gradient of the
image intensity function. The operator calculates the gradient of the image
intensity at each point, giving the direction of the largest possible increase
from light to dark and the rate of change in that direction. The result
therefore shows how sharply or smoothly the image changes at that
point.
The
operator uses two 3×3 kernels which are convolved with the original image [...]
[...] address the issue of audio/visual information description. One of the most common multimedia data is image. Therefore, image description consists one of the key components of multimedia information description in MPEG-7. In MPEG-7, image is described by its contents featured by color, texture and shape. Many works have been done in image description, they are known as Content Based Image Retrieval (CBIR). Most researches on CBIR have contributed to color/texture [...]
Order filters – Median Filter Median filter with color image. (a) Image with added salt-and-pepper noise, the probability for salt=probability for pepper=0.08. (b) After median filtering with a 3x3 window, all the noise is not removed. (c) After median filtering with a 5x5 window, all the noise is removed, but the image is blurry acquiring the “painted” effect. Order filters – Minimum and Maximum Filter Median filter with color [...]

[...] operator may detect edges as well as noise (isolated, out-of-range), it may be desirable to smooth the image first by convolution with a Gaussian kernel of width
to suppress the noise before using Laplace for edge detection:
The first equal sign is due to the fact that
So we can obtain the Laplacian of Gaussian first and then convolve it with the input image. To do so, first consider
and
Note that for simplicity we omitted the normalizing coefficient . Similarly we can get
Now we have LoG as an operator or convolution kernel [...]

[...] the newer schema but support also exists for legacy applications to use the older ECC schema. The image shows an annotated Datamatrix where the finder and synchronization patterns have been highlighted. Even though it is primarily designed to handle the the Western alphabet (ISO-8859/x code tables) it will support user prepared Unicode characters through the use of the "Extended Channel Interpretation" (ECI) mechanism. However description of the ECI standard is out of scope for this manual and the interested reader are referred to the official ECI standard document. [...]
