2. Overview Recap & User Requirements User Interface Specification High Level Design (HLD) Implementation Testing Demo

3. Recap Organize and easily retrieve images and their metadata Detect images on hard drive Eliminate duplicates Ability to tag images Manual Automatic (Object Detection) Easily retrieve images based on these tags

4. User Interface Specification

5. High Level Design Find all image files and eliminating duplicates Tag an image Manual tags (Clicking on image) Automatic Tagging (Object Detection) Search via tags

6. Implementation (cont..)

7. Automatic tag detection of images: Detecting Haar-like features

8. Implementation (cont..) Xml string is then embedded within the image Face

9. Testing Twenty users tested the application Each user received six tasks to perform

10. Testing Task 1 (Very Easy) 2 ( Easy) 3 (Moderate) 4 (Difficult) 5 (Very Difficult) Search for images Manually tag an image Automatically tag an image Search for images via tags Import a haarcascade Edit tags

11. Testing (Task 1) Task 1: Search for images on the hard drive Degree of Difficulty Number of Users

12. Testing (Task 2) Task 2: Manually tag an image Number of Users Degree of Difficulty

13. Testing (Task 3) Task 3: Automatically tag ‘Wall clocks’ and ‘Faces’ Number of Users Degree of Difficulty

14. Testing (Task 4) Task 4: Search for images via tags Number of Users Degree of Difficulty

15. Testing (Task 5) Task 5: Import a custom haarcascade Number of Users Degree of Difficulty

16. Testing (Task 6) Task 6: Edit the tags of an image Number of Users Degree of Difficulty

17. Testing (cont..)
