<p class=MsoNormal>CyeWeb supports hybrid video and audio source. This means
your USB-webcam, PCI/PCI-E capture card, hardware compression card, IP Camera,
Windows Media Stream, remote CyeWeb…, etc can be connected on the same system.
However, <b>you have to make sure there is no conflict in your hardware</b>.
For example, sometimes PCI capture cards from different bands may not be able
to work together due to driver and hardware conflicts. Your OS may crash
instantly if this situation occurs. </p>

<p class=MsoNormal style='text-indent:.5in'><img width=576 height=512
src="modules.files/image001.jpg"></p>

<p class=MsoNormal>This module allows you to select a DirectShow-based video
device as a video source. Examples of DirectShow-based device are USB webcam
and PCI/PCI-E capture cards (if the card vendor provides a driver with
DirectShow capture filter).</p>

<p class=MsoNormal>In the setting dialog you can select video standard, pixel
format, resolution (from 160x120 to 1920x1080), and frame rate (from 5fps to 60
fps). </p>

<p class=MsoNormal>In general, we recommend you to select I420 or YV12 as the
pixel format if your capture device supports them. But you should also test if
your capture device performs better on other pixel formats.</p>

<p class=MsoNormal>If you checked “Bind Module” but no video show up, you may
check “Use Device Provided Options”. We do not recommend you to use this option
unless it is necessary. In this case CyeWeb will no longer know the settings
and has no way to remember them.</p>

<p class=MsoNormal>Note:  If your computer does not have any DirectShow
compatible devices or devices specially supported by CyeWeb, the “Module Type”
option will disappear. Also, some broken driver may not implement all necessary
interfaces even it is DirectShow compatible. These devices will not show up for
selection.</p>

<p class=MsoNormal>CyeWeb initially comes with some very common network camera
modules under Unconstraint Type. The most important ones are Jpeg and Mjpeg
because most network cameras in the market today support them. You should study
the instruction menu of your camera to figure out the network address and how
to setup an ID and password.</p>

<p class=MsoNormal style='text-indent:.5in'><img width=552 height=256 id="圖片 41"

<p class=MsoNormal>If your network camera supports Mpeg4 stream and the stream
format is windows media (generally the network address would end with “.asf”),
you could try to connect with the Windows Media URL module.</p>

<p class=MsoNormal>CyeWeb natively support Mpeg4/H.264 streams with Axis
cameras, HikVision cameras/DVS, ACTi cameras, AVTech cameras and Samsung
Techwin camera, etc.  More Mpeg4/H.264 cameras will be supported in coming
updates.</p>

<p class=MsoNormal><b>Note: This module is available on CyeWeb Complete Edition
only.</b></p>

<p class=MsoNormal>This is a module to analyze video content for counting
objects, detecting loitering objects, detecting objects entering or leaving an
area …, etc. </p>

<p class=MsoNormal>This module has 2 sub-modules: object tracking and event
detection. <br>
Object tracking is a technology to track objects in video streams. The result
of object tracking is then passed to event detectors, which incorporate some
predefined rules to define in what situation an event happens.</p>

<p class=MsoNormal>Please note that this module is to analyze content but not
to show result on the screen. Please use the “Video Content Analysis Result
Presenter” in Event Handler to configure how to present analysis result.</p>

Tracker</a></h4>

<p class=MsoNormal>Object tracking is the heart of almost all event detectors.
The proper setting of object tracker is one of the most important factors to
the accuracy of detector results. You should study every single setting
carefully, do some experiments, and tune the settings to produce the best
possible result.</p>

<p class=MsoNormal>You can create multiple object trackers for multiple event
detectors. But one tracker can also be shared by multiple detectors. </p>

<p class=MsoNormal>Object tracking is computational intensive. If the object
tracker setting for 2 event detectors can be the same, they should share the
same tracker. But in some situation, using multiple trackers is more
appropriate than sharing one tracker. For example, “illegally stopped object
detector” should have its own tracker because generally its tracker settings
should be significantly different from that of other detectors.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span>Object Track Mask Regions<br>
you should mask the regions that you are not interested in. Also, you should
mask cluttering background such as trees and leaves. <br>
Always expose just the area you are interested in. The more areas an object
tracker to process, the more computation time it require.</p>

</span>Detection interval<br>

produce negative effect on accuracy while a lower value consumes more
computation time.</p>

“Moving” is a key to determine the boundary of an object and where it is. In
most case, an object is considered as an object after it has been moving for
some time. However, in some case, such as somebody drops a briefcase on the
ground, an object may appear suddenly and will never move. If you are
encountering these situations, you should uncheck this box.</p>

those sizes of objects you are interested in and ignored others. For example,
if you just want to track vehicle but not trunk, you should just add the
possible sizes of vehicle.<br>
Initially CyeWeb’s video content analysis module cannot classify objects into
real things, such as car, bike, or pedestrian (we will do this later by adding
mathematics model of real things).  However, defining sizes of objects could be
a way (though not efficient) to classify real objects at the current stage.</p>

</span>Object moving speed<br>
this value tells the moving speed of objects to be tracked. For example, if the
objects you are interested are pedestrian, you may set this to “slow”. If you
are interested in vehicle, you should set this to “fast”.</p>

<p class=MsoNormal>Note: It is hard to delivery all possible details for each
single setting. With the basic concepts, you should do experiments yourself to
study how to set the parameters for the best result.</p>

<p class=MsoNormal style='text-indent:.5in'><img border=0 width=553 height=567
src="modules.files/image012.jpg"></p>

<p class=MsoNormal>Initially CyeWeb’s video content analysis module provides
seven event detectors.  They are “Detect Object Moving inside Region”, “Detect
Object Enter or Leave Region(s)”, “Detect loitering object(s)”, “Detect objects
congregating in an area”, “Detect illegally stopped objects”, “Detect object
cross line(s)”,  and “Object counter”.</p>

<p class=MsoNormal>Some detectors can be used to detect events that are
diverted from the detector’s name. For examples, you could use “Detect Object
Moving inside Region” to detect vehicles moving in illegal direction, or you
could use “Detect illegally stopped objects” to detect suspicious objects.</p>

<p class=MsoNormal style='text-indent:.5in'><img border=0 width=322 height=466
src="modules.files/image013.jpg"></p>

<p class=MsoNormal>To add an event detector, press the add button. A dialog
will show up to choose a detector. At this time you should define a <b>tag</b>
for that detector instance. The tag will be inserted with the event being
triggered and can be used as a keyword in video searching. You can add multiple
instances of the same event detector with different settings.</p>

<p class=MsoNormal>Please note that the “object maximum allow motionless time”
setting in the selected tracker would affect this detector. If the value in the
tracker is smaller than the threshold defined in this detector, the “illegally
stopped” event will never be triggered because object stays motionless for that
long will be already considered as background. So generally this detector
should use its own tracker with a large “object maximum allow motionless time”
setting.</p>

<p class=MsoNormal>CyeWeb currently has one compression module, which performs
video/audio compression for local storage and Internet broadcast. The
compression codec for audio and video are WMA Pro and WVC1 (a VC-1 compliant
codec, which is a direct competitor to H.264. You can find more information by
searching the keyword ‘VC-1’ on <a href="http://www.wikipedia.org">http://www.wikipedia.org</a>
) respectively. </p>

<p class=MsoNormal>To locally saved or broadcast a channel, you have to bind
this module.</p>

</span><b>Storage and broadcast tabs:</b> These 2 tabs have almost the same set
of settings; one for local storage and one for broadcast. They can be equal or
different. For example, you can configure that only video samples with motion
will be compressed and propagated to broadcast modules (such as Video Server
and Window Media Broadcast), while compression for local storage is round-the-clock.<br>
In general, we recommend you to use the same settings for both storage and
broadcast, as in the figure below. If the settings for storage and broadcast
are different, 2 compressors will be used, which is quite CPU-consuming. </p>

there may be already compressed video/audio stream. For example, source from
network camera typically has a compressed Mjpeg stream. In this case you can
save a compressor.<br>
Using existing compressed stream is not mandatory. You can choose to recompress
video/audio with software WVC1/WMA codec.</p>

constant bit rate. We recommend you to use CBR if you need to webcast the
video. The default CBR bit rate is 512 Kbit/sec (524288 bit).  This value is
high enough for D1 video. If your video source is in video resolution lower
than or equal to 720*480, we recommend you to set this to a lower value, such
as 256 Kbit/sec (262144), to lower the data size.</p>

source, there may be 2 existing compressed video/audio streams—the primary and
secondary compressed stream. This setting allows you to select which stream to
be used.<br>
In hardware compression card, there is so-call “dual hardware compression”,
which offers 2 compressed streams.  <br>
Typically the quality of the primary stream is better than that of the other,
while the data size of the secondary is smaller.  This type of capture source
is very appropriate in situation that you want high quality data to be stored
locally, while small-size data to be broadcasted over Internet. Checking this

Unless you have special reason, we highly recommend you to set this value to 0.
Theoretically a higher complexity value would generate better quality and
smaller-size data at the cost of more computation time.  But in our tests, we
see high complexity value causes very high CPU usage but almost insensible

Internet, please set this value to around 2000 milliseconds. A bigger interval
would produce smaller-size data. This could be good for local storage but may
cause problem on Internet broadcast due to insufficient network bandwidth,
which causes frame dropping. If a key frame is dropped, all frames until the
next key frame will become useless and be dropped too. </p>

size according to the frame rate and resolution of your capture source. For
example, a video capture source with resolution 640x480 at 30fps and I420 pixel
format requires 640x480x30x1.5 = around 13 MB per second. So if you set the
“Pre-event time” to 2000 milliseconds (2 seconds), you would need about 26 MB

channel 2 is <a href="mms://%3cyour_internet_address%3e:9802">mms://&lt;your_internet_address&gt;:9802</a>,
and so on. &lt;your_internet_address&gt; is the Internet address of your
computer. Windows Media Broadcast is over RTSP, HTTP or TCP/IP. (If you
broadcast media data that are not compressed in WVC1/WMV3/WMA, you have to
install the corresponding codec on the remote computer. You may download the
codec pack on our website.)</p>
