2. Unclaimed bag Security threats?

3. Answer:- ?

4.  There are lots of security cameras inside the campus. So it is very difficult to checks all the images manually.  Solution :- it will be helpful if the searching process is automatic.

6.  using NTSC format  where luminance(Y), hue(I), and saturation(Q) 

7.  The RGB image and corresponding Gray image

8.  Laplacian Filter

9.  correlation takes huge time………..  So selected correlation method is used here….

12. Unnecessary points

14.  For a 600×800 image the total correlation time is 32.9220 second, where dimension of the mask is 39×49 and For the same input image and mask, 1.3590 second is required to detect the same object using proposed algorithm.  24 times faster !

15.  In a campus there may be 100 or more security cameras so the number of images to be processed may exceed 100000.  Single pc will take very long time to compute all the images……..  So…………….

16.  But this type of processing is required very rarely.  So it is not a good practice to deploy large number of computers for this.  Better to ask 3 rd party (grid) to do the processing…..

17.  The system can be thought as a single instruction multiple data set model where data sets are independent to each other.

18.  How grid split and distribute user’s program among the nodes?  Is there any standard protocol or guideline for writing c or java code that will run on grid?
