b1eaeb1960 Merge pull request #13 from KDAB/improved_qzxingfilter 
great improvements of QZXing and QZXingLive performance provided by @milianw from KDAB!
QZXingFilter becomes integral part of QZXing library source code.

594b178501 Make QZXingFilter "official" by moving it out of the example folder 
The filter is much more performant than using the QZXing API in an
imparative way for the use-case of live-analyzing video frames in QML.

61508f461a Optimize: Return the matrix reference directly instead of copying it. 
This removes another copy of frame data, thereby improving the FPS
of the QZXingFilter example noticeably.

449a808972 Crop to capture rect directly when converting RGB to grayscale 
This improves the performance since we only need to convert the
actually interesting part of the frame, instead of the full frame.

c882465649 Improve performance of rgb(a) reading, convert directly to greyscale 
This again leads to a noticeable performance improvement of the
QZXingFilter example, as we get rid of one full copy of the image
data by converting directly into greyscale, instead of first
converting to RGB and then converting to greyscale.

75b1a0d355 Further optimize QZXingFilterRunnable::processVideoFrameProbed 
Do not call detaching QByteArray::data, use constData instead.
Also hoist some constants out of the inner conversion loops and make
more variables const.

d112bf4186 Don't try harder by default in the QZXingLive example 2017-01-10 13:17:54 +01:00

7937cb84b5 Only try to mirror images when tryHarder is set to true 
Additionally, this is only done until a match is found, instead of
always applying mirroring for the 2nd, 3rd and 4th frames.

cafad4a9c0 Add captureRect functionality 
This allows one to only detect within a certain unscaled region
of the input frame. The reduction of pixels scanned leads to
a significant performance win, and the removal of the scaling
improves the quality of the checked image, thereby leading to
higher detection rates.

bd96c910e9 Merge pull request #6 from sergey-platonov/isnan-fix 
zxing::isnan for non-msvc compilers was implemented with c99 function,
which is still not fully supported by some compilers (e.g., GCC).
Added an implementation for compilers without c++11 or c99 support. And wrapped
all related code in #if.
