Abstract
Official abstract text for this publication.
The present invention provides a method of providing online information using image, including separating each of a target image, received from a user terminal, and an original image, received from an information provider apparatus, into a text region and a graphic region; selecting an important text region from the text region; extracting features from the text region, the graphic region, and the important text region, respectively; searching for the original image corresponding to the target image using the features of the text region, the graphic region, and the important text region; and searching for supplementary information related to the retrieved original image and provided the retrieved supplementary information.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of providing online information using image, the method comprising: separating each of a target image, received from a user terminal, and an original image, received from an information provider apparatus, into a text region and a graphic region; selecting an important text region from the text region based on the number of strokes to an area of the text region; extracting features from the text region, the graphic region, and the important text region, respectively; searching for the original image corresponding to the target image using the features of the text region, the graphic region, and the important text region; and searching for supplementary information related to the retrieved original image and provided the retrieved supplementary information, wherein the extracting of features from the graphic region comprises: forming a graphic image formed of only the graphic region; filling each of pixels of the graphic region from which the text region has been deleted, with a mean value of pixels of a graphic region that is closest to the graphic region; and extracting the features of the graphic region by applying a characteristic extraction algorithm to the graphic image. 2. A method of providing online information using image, the method comprising: separating each of a target image, received from a user terminal, and an original image, received from an information provider apparatus, into a text region and a graphic region; selecting an important text region from the text region based on the number of strokes to an area of the text region; extracting features from the text region, the graphic region, and the important text region, respectively; searching for the original image corresponding to the target image using the features of the text region, the graphic region, and the important text region; and searching for supplementary information related to the retrieved original image and provided the retrieved supplementary information, wherein the extracting of features from the text region comprises: forming a text image composed of only the text region; filling the text region and the graphic region of the text image with a single present color; and extracting the features of the text region by applying a characteristic extraction algorithm for an image search to the text image.
