OpenCv
1. Kuvan tuonti ohjelmaan, Qt ja OpenCv
Opencv (Open Source Computer Vision Library) on konenäkökirjasto, jolla voi toteuttaa c, c++ ja Python ohjelmia.
Opencv sisältää seuraavat ominaisuudet:
core - a compact module defining basic data structures, including the dense multi-dimensional array Mat and basic functions used by all other modules.
imgproc - an image processing module that includes linear and non-linear image filtering, geometrical image transformations (resize, affine and perspective warping, generic table-based remapping), color space conversion, histograms, and so on.
video - a video analysis module that includes motion estimation, background subtraction, and object tracking algorithms.
calib3d - basic multiple-view geometry algorithms, single and stereo camera calibration, object pose estimation, stereo correspondence algorithms, and elements of 3D reconstruction.
features2d - salient feature detectors, descriptors, and descriptor matchers.
objdetect - detection of objects and instances of the predefined classes (for example, faces, eyes, mugs, people, cars, and so on).
highgui - an easy-to-use interface to video capturing, image and video codecs, as well as simple UI capabilities.
gpu - GPU-accelerated algorithms from different OpenCV modules.
some other helper modules, such as FLANN and Google test wrappers, Python bindings, and others.
