Also take into account the matter of new/delete and malloc/free. What does the rosbag output have to do with the problem? "rosbag record -a" is not a good idea, it's better to subsribe to the specific topics you need or use You are using the parameter wrongly.

  1. I hope some one can correct me on this :) Thanks in advance, Joan.
  2. The 'fix' is for OpenCV to check that the column stride is the same as the element size, because OpenCV can only deal with arrays with contiguous data.
  3. Easy way to do that is view the > IplImage > and count how many bad pixels you have in the image.
  4. You will get a compilation error when you try to assign it to an unsigned char*, which is the underlying pixel representation in an IplImage (no matter the pixel depth or
  5. Then have a look at the relevant code.

As default, OpenCV uses BGR, but you can change this to RGB with something like cvConvertImage (I can't remember it now, but search for CV_BGR2RGB and you will find it). edit flag offensive delete link more add a comment Your Answer Please start posting anonymously - your entry will be published after you log in or create a new account. Also you should give absolute path inside the csv file. Is it ethical to use proprietary (closed-source) software for scientific computation?

Is there a way to find out if my living room ceiling has insulation? Untill now, the way I made it works was to create a .jpg file on disk from that buffer and then just call to cvloadImage(). Already have an account? I assumed that *imageBuffer was the uncompressed jpeg, but I was wrong, so actually, thanks to your help, I manage to fix it just using this 2 lines: CvMat cvmat =

Having the image 3 channels, the pixels are stored each channel in a different unsined char.

Actually I just fix it right now. http://answers.ros.org/question/12780/opencv-error-image-step-is-wrong-in-cvinitmatheader/ I take your point, and I know that OpenCV uses uchar* as the underlying pixel storage for the sake of generality.

Reload to refresh your session. I got rid of the error by giving same ratio(1:1) images.

I feel I should be able to explain this better somehow. Click on 'train neural network' and then click on 'loal neural to LUT' What is the expected output? The way it works is the following: I send to the dll 2 parameters: const char * imageBuffer, std::size_t bufferLength In the C++ side, I have a "IplImage* frame" created and Source Hi there!

For example the IplImageformat always stores it's imageData as a unsigned char pointerno matter if it is a 3-channel floating pointimage or a simple 8 bit grayscale image. So I've changed source type to 32bit float to match the ddestination.
