Good day! Im study opencv (SIFT and SURF methods). First of all i have to load image

Mat img_1 = imread(.....);

Where is imread implementation ? How its work ? I want to see source code of this method, cuz i cant get thing how its work without implementation. I think its "Integral view of image". But if i want to use it, i have to know how its work. Sure, im using opencv without commercial targets.

looking at the imread src won't help you much, imho.

instead, have a look at the feature2d tutorials

berak, thx for answer. i sew this tutorials, and btw src really couldnt help me :( can u tell me, in whick representation the image is stored ? i loaded img in Qt Creator:

QImage image(filename);

representation(data) = 0x6ba6b6e0

And loaded with opencv imread:

Mat img_1 = imread(filename, CV_LOAD_IMAGE_COLOR);

representation(data) = 0x0000000000389810

Representation of images is different. How i can conver my QT representation to cv::Mat representation ? I have to do this cuz i dont know how is work imread. i think that link can help me http://docs.opencv.org/doc/tutorials/features2d/trackingmotion/harris_detector/harris_detector.html#harris-detector and in particular http://docs.opencv.org/_images/math/4bfccbf6ce004b20fa2ece255b9d24406428c280.png
