OpenCV基本编程练习，包括显示图片，播放视频，滚动条，图片平滑，ROI，事件响应等。为了避免各个模块之间相互影响，对应的代码已经屏蔽，可以通过选择取消屏蔽相应的代码实现相应的功能OpenCVTest\OpenCVTest.sdf..........\OpenCVTest.sln..........\OpenCVTest.suo..........\..........\my metrx.xml..........\..........\OpenCVTest.cpp..........\..........\OpenCVTest.vcxproj..........\..........\OpenCVTest.vcxproj.filters..........\..........\OpenCVTest.vcxproj.user..........\..........\ReadMe.txt..........\..........\stdafx.cpp..........\..........\stdafx.h..........\..........\targetver.h..........\..........\Release\CL.read.1.tlog..........\..........\.......\CL.write.1.tlog..........\..........\.......\OpenCVTest.lastbuildstate..........\..........\.......\OpenCVTest.log..........\..........\.......\OpenCVTest.pch..........\..........\.......\OpenCVTest.unsuccessfulbuild..........\..........\.......\stdafx.obj..........\..........\.......\vc100.pdb..........\..........\Debug\CL.read.1.tlog..........\..........\.....\CL.write.1.tlog..........\..........\.....\link-cvtres.read.1.tlog..........\..........\.....\link-cvtres.write.1.tlog..........\..........\.....\link.read.1.tlog..........\..........\.....\link.write.1.tlog..........\..........\.....\mt.read.1.tlog..........\..........\.....\mt.write.1.tlog..........\..........\.....\OpenCVTest.exe.embed.manifest..........\..........\.....\OpenCVTest.exe.embed.manifest.res..........\..........\.....\OpenCVTest.exe.intermediate.manifest..........\..........\.....\OpenCVTest.lastbuildstate..........\..........\.....\OpenCVTest.log..........\..........\.....\OpenCVTest.obj..........\..........\.....\OpenCVTest.pch..........\..........\.....\OpenCVTest_manifest.rc..........\..........\.....\rc.read.1.tlog..........\..........\.....\rc.write.1.tlog..........\..........\.....\stdafx.obj..........\..........\.....\vc100.idb..........\..........\.....\vc100.pdb..........\ipch\opencvtest-c101ff59\opencvtest-296a8017.ipch..........\Debug\OpenCVTest.exe..........\.....\OpenCVTest.ilk..........\.....\OpenCVTest.pdb..........\.....\opencv_calib3d242.dll..........\.....\opencv_calib3d242d.dll..........\.....\opencv_contrib242.dll..........\.....\opencv_contrib242d.dll..........\.....\opencv_core242.dll..........\.....\opencv_core242d.dll..........\.....\opencv_features2d242.dll..........\.....\opencv_features2d242d.dll..........\.....\opencv_ffmpeg242.dll..........\.....\opencv_flann242.dll..........\.....\opencv_flann242d.dll..........\.....\opencv_gpu242.dll..........\.....\opencv_gpu242d.dll..........\.....\opencv_highgui242.dll..........\.....\opencv_highgui242d.dll..........\.....\opencv_imgproc242.dll..........\.....\opencv_imgproc242d.dll..........\.....\opencv_legacy242.dll..........\.....\opencv_legacy242d.dll..........\.....\opencv_ml242.dll..........\.....\opencv_ml242d.dll..........\.....\opencv_nonfree242.dll..........\.....\opencv_nonfree242d.dll..........\.....\opencv_objdetect242.dll..........\.....\opencv_objdetect242d.dll..........\.....\opencv_photo242.dll..........\.....\opencv_photo242d.dll..........\.....\opencv_stitching242.dll..........\.....\opencv_stitching242d.dll..........\.....\opencv_ts242.dll..........\.....\opencv_ts242d.dll..........\.....\opencv_video242.dll..........\.....\opencv_video242d.dll..........\.....\opencv_videostab242.dll..........\.....\opencv_videostab242d.dll..........\OpenCVTest\Release..........\..........\Debug..........\ipch\opencvtest-c101ff59..........\Release..........\OpenCVTest..........\ipch..........\Debug……
