Motivation Retrieve an image based on a descriptive

query: “Find me an image that is red, dark, scary, and

beautiful”

Page 3: Descriptive Semantic Image Retrieval

Content-Based Image Retrieval Retrieve an image strictly from image features

color texture shape

General semantic based image retrieval is hard “Find me a picture of a piranha”

Page 4: Descriptive Semantic Image Retrieval

Emotional Semantic Image Retrieval Query images matching emotional words or

word-pairs “Find me a happy picture”

Usually adjectives

Usually a small orthogonal subset of terms

Query via single words (or pairs)

Page 5: Descriptive Semantic Image Retrieval

Descriptive Semantic Image Retrieval Open to all descriptive words

Query via any number of words “Find me an image that is red, dark, scary, and

beautiful”

Three Components Extraction of image features

Semantic representation of image

Mapping between visuals and language

Extraction of Image Features Color (12)

Average RGB values Color count

Texture (50) Entropy

Shape (10) Eccentricity

Semantic Representation of Image How do we obtain a description?

What is a descriptive word?

What are the features?

User Input Interface

Page 12: Descriptive Semantic Image Retrieval

Bright has 11 Senses 1. (17) bright -- (emitting or reflecting light readily or in large amounts; "the sun was bright and hot"; "a

bright sunlit room") 2. (6) bright, brilliant, vivid -- (having striking color; "bright dress"; "brilliant tapestries"; "a bird with vivid

plumage") 3. (5) bright, smart -- (characterized by quickness and ease in learning; "some children are brighter in one

subject than another"; "smart children talk earlier than the average") 4. (3) bright -- (having lots of light either natural or artificial; "the room was bright and airy"; "a stage bright

with spotlights") 5. (1) bright, burnished, lustrous, shining, shiny -- (made smooth and bright by or as if by rubbing;

reflecting a sheen or glow; "bright silver candlesticks"; "a burnished brass knocker"; "she brushed her hair until it fell in lustrous auburn waves"; "rows of shining glasses"; "shiny black patents")

6. (1) bright -- (splendid; "the bright stars of stage and screen"; "a bright moment in history"; "the bright pageantry of court")

7. undimmed, bright -- (not made dim or less bright; "undimmed headlights"; "surprisingly the curtain started to rise while the houselights were still undimmed")

8. bright, brilliant -- (clear and sharp and ringing; "the bright sound of the trumpet section"; "the brilliant sound of the trumpets")

9. bright -- (characterized by happiness or gladness; "bright faces"; "all the world seems bright and gay") 10. bright, shining, shiny, sunshiny, sunny -- (abounding with sunlight; "a bright sunny day"; "one shining

morning"- John Muir; "when it is warm and shiny") 11. bright, promising -- (full or promise; "had a bright future in publishing"; "the scandal threatened an

abrupt end to a promising political career")

Narrowing Down the Feature Space Interface:

Adjectives from WordNet

Restrict characters

Reduce available senses

Page 14: Descriptive Semantic Image Retrieval

Narrowing Down the Feature Space Post Processing:

Use Synsets

Frequent synsets

Fit ORM ontology lexicons

Page 15: Descriptive Semantic Image Retrieval

Image ORM Ontology

Mapping between visuals and language Series of Neural Networks

Bayes Net

Fuzzy Logic

Evaluation Let machine label images

Let humans label images

Let different humans evaluate machine and human labels

Compare evaluations

cognition.

Establish a linguistic-visual foundation for an artificially creative artist.
