World Géonumérique On his blog, Thierry Joliveau recently presented here results on keywords and names related geomatics tool from Google Trends Google. Google Trends analyzes the frequency before a keyword into the Google search engine and provides statistical results chronological and geographical such as graphs. This tool is part of those developed in Google Labs . I've done some tests show the great variation in results by spelling words entered, which does not mean that the tool is fully discredit.
It is another tool of Google Labs, which interested me was Similar Images .
Better too long an explanation, here is the video presentation of one of the project at Google Similar Images:
Similar Images lets you search more images using image content themselves that the words associated with images. As its name suggests, focuses Similar Images find similarities in the images. Google talk instead of using "visual similarity". Following a query, a results page is displayed as one can get with the feature "classic" image search "Google.
The first example below shows the results obtained with Similar images for the keyword "France Map"
We can compare this result with that obtained with the tool "classic" "Search Images "Google:
Like the classic image search in Google, the query results are displayed as thumbnail images. It is then possible, from the menus provided for this purpose at the top of the page, select only the images of a certain size (small, medium, large, very large) or corresponding to a certain type of content (news, faces, clip art, line drawing, photo content), or by dominant color among 12 colors available. The major advantage of
Similar Images is to propose some thumbnails of the results obtained by the query, a link "Similar Images" . This link provides access to images considered similar, which also appear in the top banner after clicking a thumbnail. This feature can be very helpful to sort among the immediate results of his first complaint. Thus, in the example below the results appear to "Paris" after selecting only images of maps of Paris suggested by the link "Similar Images":
This avoids, in particular, fall images of ... Paris Hilton ...
But just like Google Trends Similar Images is very sensitive to spelling or the order of the keywords entered. Thus, in the example below, depending on whether one takes "satellite images" (above) or "satellite images" (bottom), results may differ materially.
Many other applications are looking for content, either on audio, video, text, etc.. eg TinEye or Voxalead . Google was not the exclusivity of this kind of functionality, but we know the "strike force" of the Mountain View company when she decided to pursue investment significant research and development.
Finally, how can we not question the quality and relevance of results obtained with "Similar Images" when searching for "pictures like" Michael Jackson, the man whose face image does ceased to change throughout his life ...
