I am facing precision loss while obtaining R and Q matrices using function RQDecomp3X3 in opencv. Is there a way to improve the precision for it's output. Or is it possible to achieve QR decomposition in manner similar to RQDecomp3X3 using function solve and flag DECOMP_QR

thank you, it was really helpful

I want to implement Levenberg-Marquardt Algorithm on a set of 11 number of parameters. Has anyone used CvLevMarq which can be used for non-linear square approximation? Any literature regarding the CvLevMarq is also welcomed.

So is there a way to implement the same without having any c++ files in my workspace? Because that is precisely the thing i want to avoid.

Thank you for answering. I have already implemented the wrapper using iplImage. But I wanted to know if there is any other way to get only C based solution to this.

I am aware of the function connectedComponents in OpenCV library which can give me labeled image from a binary image.

Since i want to write my code purely in C and without any wrappers, is it possible to achieve the same using OpenCV?

I am also aware of functions such as findContours and floodFill, but i am not able to achieve the proper labeling of my binary image which is provided by connectedComponents.
