Why can't different stl implementations exist using NDK?

I try to build a project based on two open source libraries. The libraries I am using are OpenCV and ceres. The libopencv_java3.so is the release OpenCV3.1.2 from the website github that include OpenCV-3.1.0-android-sdk. The libceres.so is compiled…

Ceres Solver : using smooth approximations for non-linear least squares

We are using Google ceres solver for solving optimization problems arising in a computer vision application. We are using an AutoDiffCostFunction to evaluate the residuals, the dense QR solver is able to optimize the function and find a decent…

Constraining intrinsic parameters for multi-video camera bundle adjustment within ceres-solver

I have a set of 6 video clips shot by 6 cameras atop a vehicle. I'm trying to use CERES to bundle adjust O(1.4K) frames from these 6 cameras. Presumably the intrinsic parameters for each of the 6 video cameras are constant to very good…

Ceres-Solver fails with "Terminating: Residual and Jacobian evaluation failed." when non-static variable used to define jacobian for-loop

I have a non-linear system I'm using Ceres to solve. It's a sparse system with a sparse block structure. Since I'm also working on image data, I've based my code off of the 'denoising.cc' example. The issue I'm encountering is that my code fails…

Opencv imread causes linker errors in liblapack when linking a static library that depends on OpenCV and Ceres-Solver

I am trying to set up compilation of my own library that depends on both OpenCV and Ceres-Solver (http://ceres-solver.org/) using CMake. However when doing so I get linker errors when linking my library to some executables, especially I believe…

Error using Ceres alongside a library with sse/avx

I have a templated library in which some functions are specialized for float and double types. This specialization uses sse/avx, hence, this library has the -march=native -mavx2 compiler flags. When I try to use some function (that is not…

Optimising multi-dimensional functions with Ceres

I want to use Ceres to optimise a function of n parameters. How to find the gradient of this function is unclear, although I do have a well defined cost. I have been using GSL so far, with numeric differentiation, but I thought I would try to use…

Ceres-Solver: is a mutable used by a residual functor good pratice? What are other alternatives?

As far as I understand, the interface of Ceres requires each residual to be defined as a functor where operator() is a const member function. Here is an example of what I'm interested in: class some_residual { public: template …

Ceres: Compute uncertainty on parameter

I am using Ceres to make a fit, and would like to get an uncertainty for the fit parameters. It has been suggested to use the Covariance class, but I am not sure whether I read the documentation correctly. Here is what I tried in analogy to the…

Problems building Ceres for iOS with Xcode 9

I'm trying to build Ceres 1.13.0 for iOS 10+ using Xcode 9.2 (9C40b) and CMake 3.11.0-rc3. It seems CMake doesn't recognize the clang version provided by Xcode 9. Is that what's going on? Doesn't seem like it, since an older version of Ceres used to…
