Advanced
LAB Demo
Introduction
A demo version of Advanced
Image Processing Lab.is a Matlab package intended for interactive running and
demonstration of the Labs from the Course "Advanced Image Processing
Lab"(the course and the corresponding lecture notes are available on the
Web site:www.eng.tau.ac.il/~yaro). It implements practically all topics of the
9 Labs of the course:
Lab.2.Image digitization
Lab.3.Image coding
Lab.4 Image interpolation
Lab 5.Image global and local
statistics.
Lab.6.Statistical
image and noise models and noise diagnostics
Lab.7.Image calibration and
enhancement.
Lab.8.Target locating and
object detection
Lab.9.Image restoration and
enhancement: Linear filters
Lab.10.Image restoration, enhancement
and segmentation: Rank filters.
The
package consists of a library of m-files,and use a set of test signals and
images in *.mat format (1-d signals) and in *.tif format (for images)
respectively. It requires Matlab version 5.2 and is designed as a machine
independent package. The package was developed by L.Yaroslavsky, Tel-Aviv
University (m-files, general design and editing) and A.Mochenov ,Tel Aviv
University (environmental and optimization programs)and tested by A. Alperovich and A. Shtainman.
·
Copy “AdvLabDemo_pack”
directory to the disk
·
To install the Lab.Demo,save the package to the
disk, (AdvLabdemo Directory – “LBD_m-files” ), specify for Matlab its path.
·
Specify directory with Image files (“LBD_Images” - these
must be in *.tiff format).
·
Specify directory with 1-D signals (“LBD_1D_signals” -
these must be in *.mat vector-format ECG signals etc.).
·
Copy 2 files from the directory “LBD_mat_files_first” (Inst_flag.mat,
lbdmbanner.mat) to the AdvLabdemo directory (“LBD_m-files”
).
·
Then type "advlabdemo"in Matlab
command line.
·
The window for ECG signals specification will
appear - One has to select directory where test ECG files are stored (ecg*.mat)
by browsing
Ones this is done similar prompt
appears to specify a directory for test set of images stored in TIFF format.
·
When the directory is specified similarly to the
previous step the initial installation of the ADVLABDEMO is completed.
·
The installation procedure adjusts directory’s
path and modifies file inst_flag.mat. Once the installation is completed the
DEMO , main window is opened ready to work (see AdvLabDemo Usage)
Restrictions:
1.
In
Lab2/ Quantization/ Topic 1a, in the selection of other test images
the option of Rectangle stimulus on a uniform background doesn’t work.
2.
In
Lab10/ Study of pixel neighborhoods/ Topic 1, the neighborhood window
initial values are 15x15 , and they cannot be changed because of problems in definition of Enter
values fields.
3.
For
Lab8/ Target localization in white noise/ Topic 1, one needs to add txtimgpath command with a path of text256.tiff image for a proper run of program.
The Lab is
designed on a MATLAB platform and allows to the students, in the process of
interactive work and making exercises, to master basic principles and to
develop their own intuition in digital image processing.
