Extraction of Explanatory Text for Web Images Using Similar Images and Keywords
نویسندگان
چکیده
We propose a method of extracting explanatory text of images from HTML files based both on retrieval of similar images and expansion of keywords using co-occurrence. Images in web pages often have their explanatory text in the same pages. Such explanatory text includes important keywords that explain the corresponding image. It is therefore reasonable to put these keywords to the image for fulfilling a wide variety of needs from users. In the proposed method features extracted from the image and the text complement each other to extract explanatory text effectively. From the experimental results on 995 images on the web, the proposed method yielded F-measure of 0.75.

There is a significant need to extract and recognise the semantically-important text contained in images on Web pages. This paper proposes a new approach to text extraction from this special class of images. The method attempts to emulate closer than before the way humans perceive colour differences in order to differentiate between text and background regions. Pixels of similar colour (as huma...
