Phase 1:

MIRAGE
-

from
Creation

to

Archiving



Strand :
Start
-
up Repository

funded by JISC


Between Apr. 2009
-

Sep. 2010.


Aim:


To

develop

a

repository

of

medical

images

benefiting

MSc

and

research

students

in

the

immediate

term

and

serve

a

wider

community

in

the

long

term

in

providing

a

rich

supply

of

medical

images

for

data

mining,

to

complement

MU

current

online

e
-
learning

system

OASIS+
.


Phase 2:

MIRAGE 2011


from
Archiving

to
Creation


Strand :
Take
-
up and Embedding

funded by JISC


Between Feb. 2011
-

Oct. 2011.


Aim:


To

enrich

the

current

repository

MIRAGE

with

two

necessities

of


3
D

Viewer’

and

‘Uploading’

to

meet

users’

needs,

leading

to

a

sustainable,

usable

and

flexible

model

of

data

management
.





Framework for MRIAGE

Phase 1: MIRAGE
--
from
Creation

to

Archiving


Phase 1: MIRAGE
--

GIFT
(GNU Image Finding Tool)

GIFT

is open framework for content
-
based image
retrieval and is developed by University of
Geneva.




Query by example and multiple query



Relevance Feedback



Distributed architecture (Client
-

Server)



MRML
---
C
-
S communication protocol



Phase 1: MIRAGE


Online system(1)


Server side:


Image collection: Accommodating
100,000
2D images and
100

3D
images


Visual feature extraction: Pre
-
processing off
-
line using
C++
and
Perl
.


Indexing file creation



Client side:


Interface based on
PHP

generate dynamic web pages.



Client


Server communication protocol:


MRML
: a XML based protocol

Link to OASIS+

Phase 1: MIRAGE


Online system(6)

On
-
line survey

Survey report show all respondents
'agreed
' or
'strongly agreed‘


The retrieved results meets users’ expectations


Fast and easy to use


Useful for teaching and learning

Phase 2: MIRAGE2011
----


From
Archiving

to
Creation

Aim:




To enrich the current repository MIRAGE with two necessities to meet users’
needs, leading to a sustainable, usable and flexible model of data management
.
