2018-09-04 09:13:53 -0600 | marked best answer | Build OpenCV and PCL with Cmake Hello, I am new to Computer Vision and am having trouble to build OpenCV with PCL, i could build PCL alone. Since PCL is developed to be complementary to OpenCV, it is good to call both libraries. I am using Windows 7 x64, OpenCV 3.2.0, Visual Studio 2017 (MSVC15) and PCL 1.8.0.The OpenCV installed is the Win Pack, VS is working fine and PCL was installed with the all-in-one pack (http://unanancyowen.com/en/pcl18/#Dow...). The Enviromental variable used for OpenCV are: "Path" "%OPENCV_DIR%\bin;C:\Program Files\opencv\build\x64\vc14"& "OPENCV_DIR" "C:\Program Files\opencv\build" & "OPENCV_VER" "320" and also OpenCV_DIR, changing to lowercase. The CmakeLists.txt code is and is a code from the same site as the all-in-one package: And the log given by the Cmake-gui is: (more) |

2017-08-16 12:52:08 -0600 | commented answer | Convert wiki tutorial from deprecated IplImage to Mat The Github Wiki issue was opened and now is closed. The code is updated: Wiki Page Update #9375 |
2017-08-15 09:43:53 -0600 | commented answer | Convert wiki tutorial from deprecated IplImage to Mat I tried @Ziri program and @sturkmen. Both works! Thank You! I am now trying to modify for my needs and found sturkmen's DisplayManyImages more neat than the program i made with the copy functions, because i am a newbie programmer =P |
2017-08-14 09:32:12 -0600 | commented answer | Convert wiki tutorial from deprecated IplImage to Mat I will try now, i saw this code googling, however, does it make the program heavier? To load and copy? or is it just fine? |
2017-08-14 08:52:33 -0600 | asked a question | Convert wiki tutorial from deprecated IplImage to Mat Hello, this is the Opencv's wiki tutorial: How to Display more than one image in a single window. I tried to run the code on OpenCV 3.x and didn't work. The tutorial uses IplImage that is the legacy Intel Image Processing Library for C language. The Detailed Description of the function states:
So to display many images in one display, the images are transformed into Regions of Interest and then allocated to the display. Which is the best way to do it on OpenCV 3.x? Use the legacy IplImage or convert to Mat. Conversion:I was trying to convert to Mat reading some SO and Q&A threads
Is it better to convert IplImage or maybe create a new program? Is it easy to convert this tutorial? |
2017-07-20 15:27:57 -0600 | commented question | How to get around Overlapping Problem? Yes, me neither =[ So i did some research and found that someone used mirrors to get around this problem. However, it seems to not be the best way to solve the problem |
2017-07-18 14:34:25 -0600 | commented question | How to get around Overlapping Problem? It is not just watershed, but watershed algo with distance transform, like the example of the cards: http://docs.opencv.org/3.1.0/d2/dbd/t... |

2017-07-17 07:08:33 -0600 | commented answer | How to get around Overlapping Problem? Thank you for the answer, i also received another reply: From watching the video and skimming the brochure, it seems likely that they're doing more processing rather than less. In addition to processing two views of the same scene (twice the work already) it seems likely that they're doing feature extraction and shape detection rather than using a less intensive method like watershed. I don't expect we'll attempt a 2-view tutorial using mirrors, because none of our readers are likely to have such a setup. We've stayed away from stereovision algorithms altogether up to now, because most of our readers don't have a stereovision camera setup either.

2017-07-13 07:16:24 -0600 | commented question | How to get around Overlapping Problem? When objects are falling, they overlap each other. And with watershed algorithm, the error is high. Is there an algorithm that uses 2 views and uses it to compensate overlapping objects. Like the one on the document on the link? |
2017-07-13 06:58:24 -0600 | asked a question | How to get around Overlapping Problem? Is there some algorithm that bypass the overlapping problem? I know that watershed algo can make it, however if the object is totally or almost totally overlapped it is inneficient. Doing some search I found this and the page 2 of this doc, explains what i am saying. Basically, the camera uses mirrors and have two different views of the object. Is there an algorithm that makes it? Or another way to get around overlapping? When objects are falling, they overlap each other. And with watershed algorithm, the error is high. Is there an algorithm that uses 2 views and uses it to compensate overlapping objects. Like the one on the document on the link? |
