Image processing involves improving visual appearance for human viewers and preparing images for measuring features and structures. It requires hardware with high resolution displays, sufficient storage and power, and memory bandwidth. Software like Photoshop and Corel Draw are used. Image processing of satellite data includes rectification and restoration, enhancement, and information extraction - the pre-processing of data, improving display for interpretation, and generating maps through classification.

2. Image Processing are of two aspects
i)Improving the visual appearance of images to
human viewer
ii)Preparing Images for measurement of futures
and structures present

3. HARDWARE REQUIREMENTS :
There are four requirements for a general
purpose computer to process a image.
* High Resolution Image Display
* Sufficient storage space
* Sufficient Computer Powering
* Memory transfer Bandwidth

4. Original Image(257 kb) Compressed Image (147 kb)
Compressing an Image:

5. SOFTWARE REQUIREMENTS :
* Adobe Photoshop,
lightroom
* Corel Draw
* Serif Photoplus

6. Image processing of satellite data can be
primarily grouped into three categories :
i) Image Rectification and Restoration
ii) Enhancement
iii)Information extraction.
i) Image rectification is the pre-processing of
satellite data for geometric and radiometric
connections.
ii) Enhancement is applied to image data in order
to effectively display data for subsequent visual
interpretation.
iii) Information extraction is based on digital
classification and is used for generating digital
thematic map
