This document describes the implementation of a Sobel edge detection algorithm on an FPGA. It discusses first and second order derivative edge detection algorithms. It provides an overview of the FPGA implementation including the use of block RAM for image storage, a VGA interface for display, and resource utilization. The FPGA implementation achieved a processing speed of 400 frames per second for a 500x500 grayscale image. Future work proposed improving performance and developing the design into a complete embedded system on a Zynq SoC.

The document contains charts and graphs showing the results of experiments comparing different systems for trustworthiness analysis of web search results. One chart shows that a combination of the authors' system and Google performed better than Google alone across 10 different query categories. Another chart shows the average precision of 4 different algorithms for determining the credibility of a data pair.

Finite-state technology, including automata and weighted finite state transducers (wFSTs), are compact data structures well suited to text processing and searching applications. Low level support for both automata and wFSTs is now available in Lucene and has recently enabled a number of surprisingly powerful improvements.In this joint talk, Robert Muir and Michael McCandless will provide an overview of finite-state technology and then describe how it's used today in Lucene: synonym filtering, fuzzy queries, respelling/suggesting, terms dictionary, in-memory postings format (MemoryPostingsFormat) and Japanese analysis (Kuromoji analyzer).
