In computer vision, the problem of object categorization from image search is the problem of training a classifier to recognize categories of objects, using only the images retrieved automatically with an Internet search engine. Ideally, automatic image collection would allow classifiers to be trained with nothing but the category names as input. This problem is closely related to that of content-based image retrieval (CBIR), where the goal is to return better image search results rather than training a classifier for image recognition.
Traditionally, classifiers are trained using sets of images that are labeled by hand. Collecting such a set of images is often a very time-consuming and laborious process. The use of Internet search engines to automate the process of acquiring large sets of labeled images has been described as a potential way of greatly facilitating computer vision research.

Famous quotes containing the words object, image and/or search:
“My object will be, if possible, to form Christian men, for Christian boys I can scarcely hope to make.”
—Thomas Arnold (1795–1842)
“The paranoiac is the exact image of the ruler. The only difference is their position in the world.... One might even think the paranoiac the more impressive of the two because he is sufficient unto himself and cannot be shaken by failure.”
