3. An image can be defined as a two-dimensional signal (analog
or digital), that contains intensity (grayscale), or color
information arranged along an x and y spatial axis.
Also it is defined as collection of pixels.
Mathematically it defined inters of Matrix (m x n)
Pixels – it is point that is having location(x, y) and value(I)
Two Coordinates – Spatial and Pixel Coordinates

7. Video Processing is a particular case of signal processing,
which often employs video filters and where the input and
output signals are video files or video streams. Video
processing techniques are used in television
sets, VCRs, DVDs, video codec's, video players, video
scalars and other devices. For example—commonly
only design and video processing is different in TV sets of
different manufactures.

27. Satellite imagery consists of images of Earth or other planets
collected by satellites. Imaging satellites are operated by
governments and businesses around the world.
Satellite imaging companies sell images under license. Images
are licensed to governments and businesses such as Google
Maps.
Various Types of Images:- Hyper-spectral Image /
Multi-spectral Image / Pan Sharpened Image / High
Resolution Image
33. This method usually increases the global contrast of many
images, especially when the usable data of the image is
represented by close contrast values.
Through this adjustment, the intensities can be better
distributed on the histogram. This allows for areas of lower
local contrast to gain a higher contrast.
Histogram equalization accomplishes this by effectively
spreading out the most frequent intensity values.
