Milian Wolff 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.

Milian Wolff 3eb5b0b869 Cleanup debug code, save at most 100 images. 2017-01-10 13:17:54 +01:00
Milian Wolff bc2badb5b5 Optimize: reduce memory allocations, convert directly to grayscale
This dramatically improves the performance of the QZXingFilter.

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

Milian Wolff 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.

favoritas37 fa186c2cc9 Added new example project for live decoding in QtQuick 2 (contibution of Luiggi Reffatti from Fira Soft ). Will be examined in the future to embed QZxingFilter implementation to the main implementation fo the library. 2016-09-27 03:06:28 +03:00
