DCT_IDCT
to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression
for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution
now compare our special 8X8 functions with the internal general functions
use this code:
A = int32(100*rand(8,8))
tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc
tic for i = 1 : 1000 idct2(dct2(A)) end toc
i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

负向选择算法的一个例子,它的基本思想就是通过采集正常数据集合生成检测器集，然后将待测数据与抗体集合中全部元素进行匹配计算，如与任一元素的匹配达到一定阈值，即判断该数据异常。(An example of negative selection algorithm. The basic idea is to collect the normal data set generated by the detector set, and then tested the data collection with the antibody to match all the elements of calculation, if any element of the match reaches a certain threshold, that determine the data exception.)
