This approach addresses two difficulties simultaneously: 1)
the range limitation of mobile robot sensors and 2) the difficulty of detecting buildings in
monocular aerial images. With the suggested method building outlines can be detected
faster than the mobile robot can explore the area by itself, giving the robot an ability to
“see” around corners. At the same time, the approach can compensate for the absence
of elevation data in segmentation of aerial images. Our experiments demonstrate that
ground-level semantic information (wall estimates) allows to focus the segmentation of
the aerial image to find buildings and produce a ground-level semantic map that covers
a larger area than can be built using the onboard sensors.
Semantic analysis of multimedia content is an on going research
area that has gained a lot of attention over the last few years.
Additionally, machine learning techniques are widely used for multimedia
analysis with great success. This work presents a combined approach
to semantic adaptation of neural network classifiers in multimedia framework.
It is based on a fuzzy reasoning engine which is able to evaluate
the outputs and the confidence levels of the neural network classifier, using
a knowledge base. Improved image segmentation results are obtained,
which are used for adaptation of the network classifier, further increasing
its ability to provide accurate classification of the specific content.
We address the problem of predicting a word from previous words in a sample of text. In particular,
we discuss n-gram models based on classes of words. We also discuss several statistical algorithms
for assigning words to classes based on the frequency of their co-occurrence with other words. We
find that we are able to extract classes that have the flavor of either syntactically based groupings
or semantically based groupings, depending on the nature of the underlying statistics.
Perl and XML
XML is a text-based markup language that has taken the programming world by storm. More
powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and
resilient. XML is the perfect tool for formatting documents with even the smallest bit of
complexity, from Web pages to legal contracts to books. However, XML has also proven itself to
be indispensable for organizing and conveying other sorts of data as well, thus its central role
in web services like SOAP and XML-RPC.

In this application note we will only refer to the FX1. The
same terminologies and concept is also used in the FX2. The
FX2 has identical FIFO architecture and the same number of
endpoints as the FX1
R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They
also have a 128-byte page programming function to make their write operation faster.
Note: Renesas Technology鈥檚 serial EEPROM are authorized for using consumer applications such as
cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology鈥檚
