TRANSCRIPT
TECHNOLOGY SUMMARY (1)
• Image Retrieval System• Managing personal image is difficult
• Manual tagging of all the images?• Need to remember where are images (local path, FB,
flicker)? • Need to remember when did you take it?
IMAGE RETRIEVAL SYSTEM
• When user provides a textual query,• It would be used to find relevant (positive) / irrelevant (negative) web images
• Then, a classifier (e.g. decision stump ensemble classifier) is trained based on these loosely labeled web images.
• And then consumer photos can be ranked based on the classifier’s decision values.
• The user can also perform relevance feedback to refine the retrieval results.

TECHNOLOGY SUMMARY (2)
• Social Oracle• Exchange name card? • Embarrassment when meeting known people but
forget their names?• Business intelligent?• Applicable to the following scenarios
• Trade show• Networking session• Teleconference• Distance learning & Remote education• Logging in/out system
SOCIAL ORACLE
TECHNOLOGY OFFERING
• Genetic framework for object recognition
• Expert knowledge for the pattern recognition
• Core engine and the associated API call• General object retrieval based on keyword• Relevance feedback• Face detection and recognition• Logging system (face verification)
POTENTIAL NEW VENTURE
• Targeted smart TV advertisement• Interactive and intelligent• Similar object retrieval where customer can find
information (price, reviews, etc.)
• Logging in/logging out system (face verification)• ID card fraud• It is useful for outlet staff management system
(KFC, MacDonald, etc.)
