IMAGE PROCESSING
ABSTRACT
The ultimate aim in a large number of image processing applications is to extract important
features from image data, from which a description, interpretation, or understanding of the scene
can be provided by the machine. Image processing can be defined as, the processing or altering
an existing image in a desired manner. This system allows the user to take hard copy of the
image using printer routines and allows the user to store screen image into the disk file using file
format (bmp, jpg, gif). Image processing in its general form pertains to the alteration and analysis
of pictorial information. We find instances of image processing occurring all the time in our
daily lives. Probably the most powerful image processing system is the human brain together
with the eye. The system receives, enhances and stores images at enormous rates of speed.
The objective of image processing is to visually enhance or statistically evaluate some
aspect of an image not readily apparent in its original form. The basic principle of image
processing operations carried out will assist us in greater perception and vision but does not add
any information content. This objective is carried out through development and implementation
of processing means necessary to operate upon images.
The recent availability of sophisticated semi conductor digital devices and compact
powerful computers, coupled with advances in image processing algorithms, has brought digital
image processing to the fore front. Digital image processing has a broad spectrum and
applications, such as remote sensing via satellites and other spacecraft image transmission and
storage for business applications, medical processing, radar sonar and acoustic image processing,
robotics and automated inspection of industrial parts.
There are various features provided by system to edit an existing image, which are as
follows
Image scaling includes zooming and shrinking images. We can use enlarging to zoom in
on the art of an image for closer examination. Image shrinking is useful for saving disk space,
fitting a large image into smaller display and pasting several images into one image of the same
size.

Image compression tool is an application, which works with BMP (bit map pattern File
Format) gray scale images. The user will send images and according to the specification they
will be modified.
Image rotation tool is used to rotate the image by the specified angle. Resembling is used
to increase the size of each pixel by a certain factor. We have used various filtering techniques
like lightening, darkening, embossing, sharpening, softening etc.
Edges characterize object boundaries and are therefore useful for segmentation,
registration, and identification. Our system allows the user to detect the edges in a given image.
We have developed a program, which can be used on compressed/uncompressed BMP, JPG, and
GIF file formats to perform any of the above-mentioned functions.
Existing System:
There are applications is to extract important features from image data, from which a
description, interpretation, or understanding of the scene can be provided by Machine.
But there is no proper processing can be defined as, the processing or altering an
existing image in a desired manner.
Proposed System:
The powerful image processing system is the human brain together with the eye. The
system receives, enhances and stores images at enormous rates of speed. Image compression tool
is an application, which works with BMP (bit map pattern File Format) gray scale images. The
user will send images and according to the specification they will be modified. Image rotation
tool is used to rotate the image by the specified angle. Resembling is used to increase the size of
each pixel by a certain factor

Modules:
Administrator:
Admin is the authorized person to maintain Image Processing application.He can add uses of
this application and can update and delete the users.
User Module:
User can load the images to be processed and can add the special effects and many other
features to the existing application .
File Module:
In this module the files can be created, opened and loaded. A file can be selected to process the
image .The files are of type image.
Effects Module:
Image can be blurred, sharpen , brightness can be increased and decreased. Image can be
displayed in negative grayscale , Embossed and Engraved etc.
Extras Module:
In Extras module image height , width , measurements (inches and decimals ) can be changed
.Image can be zoomed in and out. Mirror image can be displayed image can be flipped
horizontally and vertically.
NECESSITY OF IMAGE PROCESSING:
Even though human beings are adept at interpreting images there are certain thresholds
beyond which we cannot detect just-noticeable differences in the imagery. For example an
analyst can detect only 8 to 16 shades of gray, even when data is recorded with 256 shades of
gray. Hence , one may not be able to interpret data in the remaining shades of gray. Also it is
necessary to continuously track large amounts of data and its storage is also a problem. To avoid
all these difficulties one shall prefer processing of images by digital computers, which processes
at a much faster rate than human beings do.

APPLICATIONS OF IMAGE PROCESSING:
Applications of image processing include several fields such as
1. Remote sensing 2. Pictorial database
3. Radiology 4. Graphics design
5. High energy physics 6. Photo editing
7. Character recognition 8. Finger print matching
9. Cytology 10. Defense applications
11. Metallurgy
