Abstract
In this paper, we present a new approach of locating informative zones through extracting colorimetric features from a colored document images. The aim of this study is to obtain anchors which will allow spotting and retrieving textual information. The proposed approach is lying on three major steps. First step is to apply a noise filter while making sure that no new colors will emerge and edges will be preserved. Second is to detect homogenous regions within the image by quantifying colours through combining layers of different color spaces. Finally is to detect, from the segmented image, the components satisfying the rectangularity criterion. This approach has been evaluated over 134 document images dataset. The outcomesshow that the approach is reliable and efficient as we combine layers from different color spaces.
