Technical Progress
There is a growing interest in CBIR because of the limitations inherent in metadata-based systems, as well as the large range of possible uses for efficient image retrieval. Textual information about images can be easily searched using existing technology, but requires humans to personally describe every image in the database. This is impractical for very large databases, or for images that are generated automatically, e.g. from surveillance cameras. It is also possible to miss images that use different synonyms in their descriptions. Systems based on categorizing images in semantic classes like "cat" as a subclass of "animal" avoid this problem but still face the same scaling issues.
Potential uses for CBIR include:
- Architectural and engineering design
- Art collections
- Crime prevention
- Geographical information and remote sensing systems
- Intellectual property
- Medical diagnosis
- Military
- Photograph archives
- Retail catalogs

Famous quotes containing the words technical progress, technical and/or progress:
“I rather think the cinema will die. Look at the energy being exerted to revive it—yesterday it was color, today three dimensions. I don’t give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.”
—Orson Welles (1915–1984)
“A technical objection is the first refuge of a scoundrel.”
—Heywood Broun (1888–1939)
“The human race is yet in its infancy—no, not infancy; infancy is innocent and sweet—it is in its ugly boyhood, half way between the child and the man—in a state of semi-barbarism.”
—Anonymous, U.S. magazine contributor. Herald of Progress (no dates available)
