OBJECTIVES To identify risk factors for mesh erosion in women undergoing vaginal sling procedures for urinary incontinence with synthetic meshes, and to estimate the incidence of mesh erosion after these procedures. STUDY DESIGN Retrospective study of women who underwent vaginal sling procedures between January 2007 and January 2013. In total, 1439(More)
This paper discusses a practical design experience pertaining to a tracking system employing optical flow. The system was previously extracted from an existing software implementation and modified for FPGA deployment. Details are provided regarding transference of the resulting high-level design to a usable form for FPGA fabrics. Furthermore, discussion is(More)
This work focuses on the search of a sample object (car) in video sequences and images based on shape similarity. We form a new description for cars, using relational graphs in order to annotate the images where the object of interest (OOI) is present. Query by text can be performed afterward to extract images of OOI from an automatically preprocessed(More)
—With the rapid growth of multimedia information in forms of digital image and video libraries, there is an increasing need for intelligent database management tools with an efficient information retrieval system. For this purpose, we propose a hierarchical retrieval system where shape, color and motion characteristics of human body are captured in(More)
We describe a peer-to-peer multiple-camera architecture for distributed real-time gesture recognition system. Previous work attaches multiple cameras to a server. This simplifies many design problems but is impractical for real-world installations. Our architecture uses a network of relatively inexpensive cameras to gather images in order to provide high(More)
