opencv 2.0里面的变化还不少,采用lapack数学库应该是一个巨大的进步。LAPACK (Linear Algebra PACKage) 是Oak Ridge 国家实验室、加州大学Davis 分校和Illinois 大学等联合开发的线性代数函数库,用fortan语言编写,有f2c的c接口,用于在不同高性能计算环境上高效求解数值线性代数问题。使用lapack应该能大大提高OpenCV的算法效率。这其实也是MATLAB曾经走过的路。

CXCORE now uses Lapack (CLapack 3.1.1.1 in OpenCV 2.0) in its various linear algebra functions
      (such as solve, invert, SVD, determinant, eigen etc.) and the corresponding old-style functions
      (cvSolve, cvInvert etc.)

                  Note, that only a subset of package is used in OpenCV.
                  It can be extended and/or replaced with future upstream releases
                  in the future.
