2. Table of contents Rationale Background Methods and System Design
Performance Benchmark
Future Work

3. Rationale
Investigate the limitations and constraints of working with large images and develop a web-based solution for it.
Provide real time image interaction over the internet.

4. Background Constraints Low bandwidth (specially in mobile devices)
Size of images slow down transmission as they become larger
Solutions
Progressive transmission of image
On-demand delivery of specified image section

5. Method and System Design
On-demand delivery of specified region of interest
Drag and select region of interest
Caching algorithm
Approximate matches

7. Performance benchmark

8. Future Work
Combine our solution with various other techniques to improve image retrieval time.
Integrate and port image database application to the new hardware.
Utilize developed software as a component of an application with bigger scope.
