Version updates and fixes:
- Fixed registered issues/requests:

- Issue 92: Check for subscribers to VideoCaptureDevice.NewFrame event before copying bitmap data;
- Issue 94: Request to add Offset to Convolution filter;
- Issue 95: Error in AForge.Imaging.Filters.Crop.ProcessFilter().
- AForge.Fuzzy
- New class SingletonFunction:
new kind of membership function, to represent classical numerical numbers in fuzzy domain.
- Inference System was modified to allow the user to access the fuzzy output before defuzzyfing.
- Some other minor updates caused by received feedback.
- AForge.Imaging
- All exceptions classes, which were introduced in BETA versions, are renamed to have Exception ending.
- Added Threshold
property to the Convolution filter, which allows to set value to be added to weighted sum of pixels.
- Crop filter bug is fixed (the filter was calculating pixel size incorrectly).
- Fixed pixel size calculation in ContrastStretch filter.
- ExtractChannel and
ReplaceChannel filters
are extended to support extraction of alpha channel in addition to RGB channels.
- Added image processing filter to
extract normalized RGB channels.
- Added SimplePosterization filter.
- AForge.Video.DirectShow
- Video classes are updated to skip preparing new video frame, if nobody is subscribed for NewFrame event
(decreases CPU usage if no subscribed clients).
- AForge.Vison
- The namespace
was completely redesigned to introduce motion detection and motion processing algorithms.
In the past both these algorithms were part of each motion detection class, which was not flexible, not reusable
and not extendable.
- AForge.NET Framework's samples
- Motion Detection sample application is updated to use new classes of the redesigned AForge.Vision namespace.
Also added feature to show motion history.
In addition, please, take a look at release notes of 2.0.0 BETA version to get full information
about changes since the last 1.7.0 release.
