What we can, what we can’t and what purpose do we attain to?

We develop the software for automatic adult images detection. And we press towards adaptation the best up-to-date methods (based on analysis of colours, texture, shapes; with using machine learning techniques) for improvement our porno filter. We dynamically move to this aim attainment and at present time our filter is not bad at all (see screenshot).
We [...]

Do web search giants and smaller ones neglect image retrieval?

Ignoring image retrieval, based on visual characteristics, is, at least, short-sighted search policy. Of course, direct search by image example in large databases is very time-expensive process. Most web engines offer different instruments for more precise (visual similar) search in hits, received after text query.
Google has it’s own Google Similar Images Labs. So we can [...]

In solving what tasks can CBIR aid?

Here the most actual applications of CBIR are presented:

detection of objectionable content (porno, erotics and so on);
person identification (by means of face detection and recognition techniques), matching with celebrities (like Picitup Celebrity Match);
criminal identification (fingerprint, face, iris);
search by image sample, outline and sketch (by colour, set of colours, texture, shape, spatial layout and other features);
search [...]

What is Content-based image retrieval?

Wikipedia:
“Content-based image retrieval (CBIR), also known as query by image content (QBIC) and content-based visual information retrieval (CBVIR) is the application of computer vision to the image retrieval problem, that is, the problem of searching for digital images in large databases“
Ok. It is absolutely correct.
All web search engines leaders, such as Google, Yandex, Yahoo, Ask [...]
