INTRODUCTION 為什麼 image 無法處理的像 text 一樣好

Text is man’s 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 The theoretical foundation behind ho

w we humans interpret images is still an open problem A brief scanning of about 300 relevant pa

pers published in the last five years revealed that less than 20% were concerned with applications or real-world systems

Feature Extraction Color + Texture 抽取

“Wavelet-Based Texture Retrieval Using Generalized Gaussian Density and Kullback-Leibler Distance”

Shape “Shape Matching and Object Recognition Usi

ng Shape Contexts” (is fairly compact yet robust to a number of geometric transformations)

atching for Picture Libraries” (semantics-sensitive feature selection)

Approaches to Retrieval Region based image retrieval

Approaches to Retrieval Windowed search

nchoring 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)

Annotation and Concept Detection

Supervised classification “Image Classification for Content-Based Index

ing” (involving simple concepts such as city, landscape, sunset,and forest, have been achieved with high accuracy)

Translation approach “Object recognition as machine translation: L

earning a lexicon for a fixed image vocabulary” ( 我們在 clef 2004 就是 follow 這方法 )

Annotation and Concept Detection

為何如此困難 We humans segment objects better than machi

nes, 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

Relevance Feedback and Learning

“Relevance Feedback in Image Retrieval: A Comprehensive Review”

Problems One problem with RF is that after every round o

f user interaction, usually the top results with respect to the query have to be recomputed

Another issue is the user’s patience in supporting multi-round feedbacks

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
