ImageGear22.Recognition Assembly > ImageGear.Recognition Namespace > ImGearRecImage Class : DetectSkew Method |
Depending on the current setting of the Image deskewing and Image rotation modes, this method returns either with the detected image skew / orientation or with the current values of these settings.
When the image is not bitonal, in some rare cases Preprocess method can deskew the image more accurately than DetectSkew / Deskew methods. This is because DetectSkew
uses a simpler and faster binarization algorithm than the Preprocess
. The latter can realize that the calculated slope value is unreliable and then binarize the image again with a more precise method and repeat the skew detection.
