In this paper, we propose a new approach to logo detection and extraction in document images that robustly classifiesand precisely localizes logos using a boosting strategy across multiple image scales. At a coarse scale, a trained Fisher classifier performs initial classification using features from document context and connected components. Each logo candidate region is further classified at successively finer scales by a cascade of simple classifiers, which allows false alarms to be discarded and the detected region to be refined. Our approach is segmentation free and layout independent. We define a meaningful evaluation metric to measure the quality of logo detection using labeled groundtruth. We demonstrate the effectiveness of our approach using a large collection of real-world documents. %B The 9th International Conference on Document Analysis and Recognition (ICDAR 2007) %C Curitiba, Brazil %P 864 - 868 %8 2007/// %G eng
