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

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

User Interface Specification

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

Implementation (cont..)

Automatic tag detection of images: Detecting Haar-like features

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

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

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

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

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

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

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

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

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