This paper deals with the topic of the retrieval of document images focused on a specific application: the ornaments of the hand-press period. It presents an overview as a result of the work and the discussions undertaken by a workgroup on this subject. The paper starts by giving a general view about digital libraries of ornaments and associated retrieval problematics. Two main issues are underlined:content...
Saliency models have been extensively studied for static images and the focus is now on moving images. There is a central bias in both cases that is emphasized in the dynamic case. One aspect in this latter is the camera motion that influences the scene interpretation. The movie director exploits this motion to make the observer focus on the targeted object which is often in the center of the scene...
As ancient documents are being digitized, systems for retrieving documents or images can now be found in digital libraries. With regard to illustrations, the content-based image retrieval is difficult and the user often needs to check visually the similarity of the retrieved images. This process is not entirely reliable since very similar images (impressions, ornamental letters) can actually be printed...
This paper presents a quantification method which can be used to quantify the evolution of a brain tumor with time. From two segmented volumes, a local distance volume (LDV) based on Hausdorff distance is computed to show the true physical local distances between them. In the case of tracking a tumor volume during a therapeutic treatment, local variations can thus be shown by the LDV in particular...
Image similarity measure is widely used in image processing. For binary images that are not composed of a single shape, a local comparison is interesting but the features are usually poor (color) or difficult to extract (texture, forms). We present a new binary image comparison method that uses a windowed Hausdorff distance in a pixel-adaptive way. It enables to quantify the local dissimilarities...
