TITLE OF RESEARCH WORK
A Signal Algebra Operator Approach to the
Analysis and Design of Image Processing Algorithms for Java
This work deals with the implementation of a
based environment (called
CID) which provides
set of operators for Image Processing according to the constraints imposed by the Signal Algebra
Implemented operators includes
(Absolute value, Clamp,
and Color Convert), A
(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
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 (
onvolution and Cyclic
(Conjugate, Phase, Hadamard Product and Shifting).
has the option of allowing end
users to add their own customized algorithms as
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
for the research.

Tools and Applications
The core of the application has been implement
Java 2 Platform, Standard Edition, v 1.4.2.
Some of the operators
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

RELATION OF RESEARCH WORK TO WALSAIP PROJECT
Related to WALSAIP project, this work contributes to provide a software tool for image
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
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.
A prototype has been defined as “an implementation entity with an associated user’s guide”. A
