Image type labeling method based on phrase bag model

The invention provides an image type labeling method based on a phrase bag model, which introduces position information among vision words based on the existing bag-of-words model representation and provides the phrase bag model representation strategy. The method effectively solves the contradiction between insufficient discrimination because the traditional bag-of-words models lack position information and sensitivity to target displacement after adding the blocked position information, eliminates the sensitivity to target displacement in the image while introducing the position information among the vision words and increasing discrimination, effectively improves the performance of the image type labeling system and has important application value.
