Retrieval on Parametric Shape Collections

Shape-Based Image Retrieval in Botanical Collections

Apart from the computer vision community, an always increasing number of scientific domains show a great interest for image analysis techniques. This interest is often guided by practical needs. As examples, we can cite all the medical imagery systems, the satellites images treatment and botanical databases. A common point of these applications is the large image collections that are generated ...

Document Retrieval on Repetitive Collections

Document retrieval aims at finding the most important documents where a pattern appears in a collection of strings. Traditional pattern-matching techniques yield brute-force document retrieval solutions, which has motivated the research on tailored indexes that offer near-optimal performance. However, an experimental study establishing which alternatives are actually better than brute force, an...

Browsing Shape Collections

Large collections of shapes are becoming freely available, and we will soon need tools that quickly give an overview of the contents of a shape database. We present a browsing tool that produces a hierarchical, cluster-based overview of a shape collection, and allows users to zoom in on individual clusters to get more detailed views. Our browsing interface is particularly effective for analyzin...

Retrieval from Document Image Collections

This paper presents a system for retrieval of relevant documents from large document image collections. We achieve effective search and retrieval from a large collection of printed document images by matching image features at word-level. For representations of the words, profile-based and shape-based features are employed. A novel DTWbased partial matching scheme is employed to take care of mo...
