TITLE OF RESEARCH WORK
:

A Signal Algebra Operator Approach to the
Analysis and Design of Image Processing Algorithms for Java
-
based Web
-
enabled Applications

Research Description:


This work deals with the implementation of a
Java
-
based environment (called

J
-
CID) which provides
a
set of operators for Image Processing according to the constraints imposed by the Signal Algebra
of complex
-
valued images.
Implemented operators includes
P
oint operators

(Absolute value, Clamp,
and Color Convert), A
rithmetic opera
tors

(Addition, Subtraction, Multiplication and Division between
images and by constants; also includes Exponential and Log operations)
,
Spatial operators (Invert
color, Crop, Resizing, Rotation, and Flipping), Morphological operators (Dilation and Erosio
n),
Convolution operators (Sharpening, Blurring, Embossing, Edge Detection which includes Sobel,
Prewitt, Freichen and Roberts; Filtering which includes Low Pass, High Pass, Laplacian and
Gaussian; and 2D Fast Fourier Transform), Cyclic operators (
Cyclic C
onvolution and Cyclic
Correlation
)
and C
omplex operators

(Conjugate, Phase, Hadamard Product and Shifting).


This
environment

has the option of allowing end
-
users to add their own customized algorithms as
encapsulated operators
.

O
ther features of the envi
ronment are the remote connection via Java FTP
in order to get image files from remote machines, and the connection to a central database that
contains raw data acquired by some sensors
configured

for the research.

Tools and Applications
:


The core of the application has been implement
ed

using
Java 2 Platform, Standard Edition, v 1.4.2.
Some of the operators
invoke

methods from
the Java Advanced Imaging (JAI) API which supports a
simple programming model to manipulate images. Also it is used the Java Image I/O API which
provides “a pluggable architecture for working with images stored in files and accessed across the
network”
.

RELATION OF RESEARCH WORK TO WALSAIP PROJECT
:




Related to WALSAIP project, this work contributes to provide a software tool for image

analysis
which could facilitate the work of scientists of related
areas to environmental sciences, in this
moment in a local manner, and soon in a distributed manner.











IMAGE REPRESENTATIVE OF RESEARCH WORK
:




This s
cheme shows a local user configuration. This considers that user can operate over the
information he/she has in its own system, and from remote machines using Java FTP as channel of
communication. User can make use of utilities from J
-
CID (the Java envir
onment), MATLAB and the
GIS he / she has installed.

RESEARCH DEMONSTRATION
:




A prototype has been defined as “an implementation entity with an associated user’s guide”. A
research demonstration

is a manner of best showing to the public a basic
proto
type

of your
research work where you have
succeeded in implementing

novel software/hardware entities
such

as
concepts, tools, and application services
.


Please provide in this section a description of your research demonstration and how to have access
to s
uch demonstration if you have succeeded in developing a demonstration. If you
DO NOT

have a
research demonstration at this time, please used this space to formulate a proposal for a research
demonstration. Please, be advised that your proposed research dem
onstration
MUST
be completed
by Friday, December 1, 2006
, when
you MUST submit a
progress report

of your
on going
research
work.

This progress report will be utilized as one of the decision elements for the availability of
WALSAIP research assistantship f
unds for the second semester of the 2006/2007 academic year.
