Title: Content-Based Image Retrieval - Approaches and Trends of the New Age


1
Content-Based Image Retrieval - Approaches and
Trends of the New Age
  • Ritendra Datta, Jia Li, and James Z. Wang
  • The Pennsylvania State University
  • MIR2005

INTRODUCTION
  • ???image??????text???
  • Text is mans creation, images are a mere replica
    of what man has seen
  • Interpretation of what we see is hard to
    characterize
  • visual similarity ! semantic similarity
  • CBIR has grown tremendously after 2000, not just
    in terms of size, but also in the number of new
    directions explored

INTRODUCTION

INTRODUCTION
  • The theoretical foundation behind how we humans
    interpret images is still an open problem
  • A brief scanning of about 300 relevant papers
    published in the last five years revealed that
    less than 20 were concerned with applications or
    real-world systems

5
CBIR??????
  • Feature Extraction
  • Approaches to Retrieval
  • Annotation and Concept Detection
  • Relevance Feedback and Learning
  • Hardware and Interface Support

6
Feature Extraction
  • ??? Color Feature
  • An Efficient Color Representation for Image
    Retrieval (???histograms?)
  • Multiresolution Histograms and Their Use for
    Recognition (??textured image)
  • Image retrieval using color histograms generated
    by Gauss mixture vector quantization
    (??GMVQ?color histogram)

7
Feature Extraction
  • Color Texture ??
  • Wavelet-Based Texture Retrieval Using
    Generalized Gaussian Density and Kullback-Leibler
    Distance
  • Shape
  • Shape Matching and Object Recognition Using
    Shape Contexts (is fairly compact yet robust to
    a number of geometric transformations)

8
Feature Extraction
  • Segmentation
  • Normalized Cuts and Image Segmentation
    (????????)
  • Blobworld Image Segmentation Using
    Expectation-maximization and Its Application to
    Image Querying (????????)
  • Segmentation of Brain MR Images Through a Hidden
    Markov Random Field Model and the
    Expectation-Maximization Algorithm (??medical
    imaging)

9
Feature Extraction
  • ?????
  • Image retrieval using wavelet-based salient
    points
  • ????feature
  • Application-specific feature sets (????)
  • SIMPLIcitySemantics-Sensitive Integrated
    Matching for Picture Libraries
    (semantics-sensitive feature selection)
  • Feature Selection for SVMs (?classifier)

10
Approaches to Retrieval
  • Region based image retrieval
  • A Scalable Integrated Region-Based Image
    Retrieval System
  • region-based querying (BlobWorld)
  • Vector quantization (VQ) on image blocks
  • Keyblock An Approach for Content-based Image
    Retrieval (generate codebooks for representation
    and retrieval, taking inspiration from data
    compression and text-based strategies)

11
Approaches to Retrieval
  • Windowed search
  • Object-Based Image Retrieval Using the
    Statistical Structure of Images (more effective
    than methods based on inaccurate segmentation)
  • Anchoring-based image retrieval
  • A Study of Image Retrieval by Anchoring
    (Anchoring is based on the idea of finding a set
    of representative anchor images and deciding
    semantic proximity between an arbitrary image
    pair in terms of their similarity to these
    anchors)

12
Approaches to Retrieval
  • Probabilistic frameworks for image retrieval
  • A Probabilistic Architecture for Content-based
    Image Retrieval

13
Annotation and Concept Detection
  • Supervised classification
  • Image Classification for Content-Based Indexing
    (involving simple concepts such as city,
    landscape, sunset,and forest, have been achieved
    with high accuracy)
  • Translation approach
  • Object recognition as machine translation
    Learning a lexicon for a fixed image vocabulary
    (???clef 2004??follow???)

14
Annotation and Concept Detection
  • ??????
  • We humans segment objects better than machines,
    having learned to associate over a long period of
    time, through multiple viewpoints, and literally
    through a streaming video at all times
  • The association of words and blobs become truly
    meaningful only when blobs isolate objects well

15
Relevance Feedback and Learning
  • Relevance Feedback in Image Retrieval A
    Comprehensive Review
  • Problems
  • One problem with RF is that after every round of
    user interaction, usually the top results with
    respect to the query have to be recomputed
  • Another issue is the users patience in
    supporting multi-round feedbacks

16
REAL-WORLD REQUIREMENTS
  • Performance
  • Semantic learning
  • Volume of Data
  • Concurrent Usage
  • Heterogeneity
  • Multi-modal features
  • User-interface
  • Operating Speed
  • System Evaluation

CONCLUSIONS
  • We have presented a brief survey on work related
    to the young and exciting fields of content-based
    image retrieval and automated image annotation,
    spanning 120 publications in the current decade
  • We have laid out some guidelines for building
    practical, real-world systems
