一个理想的系统应是R,S尽量小，而P,A尽可能大。而在一个实际系统中，S,R是相互制约的，拒识率R的提高总伴随着误识率S的下降，与此同时识别率A和识别精度P的提高。因此，在评价手写数字识别系统系统时，我们必须综合考虑这几个指标。另外，由于手写数字的书写风格、工整程度可以有相当大的差别，因此必须弄清一个指标在怎样的样本集合下获得的。

The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

研究了基于块填充的图像修复算法,修复图像的质量容易受到待修复区域边界像素修 复顺序的影响,通过分析待修复区域像素点所在模块的图像特征,改进了填充算法的优先权, 分别是基于P-Laplace算子和Euler’s elastica模型的优先权计算方法的改进。实验结果证实了文中 所介绍算法能有效提高重建图像的感知质量。

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.
