Analyzing and manipulating of a
digitized images especially in order to improve its quality. Image processing
generally involves three steps:
1). Import an image with
an optical
scanner or directly through digital
photography.
2). Manipulate or
analyze the image in some way. This stage can include image
enhancement and data
compression, or the image may be analyzed to find patterns that
aren't visible by the human eye. For example, meteorologists use image
processing to analyze satellite photographs.
3).Output the
result. The result might be the image altered in some way or it might be a
report based on analysis of the image.
