    Smoothing an image multiple times fast

    Hi,
    I need a fast way to smooth an image multiple times fast.
    The way that i am currently using works like this(written in c#)
    NOTE i am only smoothing the R value of the RGB color
    Code:
    for(int i=1;i<height-1;i++)
{
   for(int j=1;j<width-1;j++)
   {
      int n1 = image[j,i-1].R;
      int n2 = image[j,i+1].R;
      int n3 = image[j-1,i].R;
      int n4 = image[j + 1, i].R;
    ...

      Need an algorithm to divide a number into unequal integral value parts

      Ok, so here is the problem. I have a number, and I need to divide it into maximum unequal parts such that no part is less than 25 in value. Even if you cannot solve the problem, any help or ideas are appreciated. Thanks!

        Accurate Mass to Molecular Weight Algorithm

        I am trying to reduce my data entry workload through automation of an accurate mass calculator. I have a table of accurate "mass to charge" output vs. intensity from an agilent mass spectrometer. Currently I have to key input each of these molecular weights into the "Agilent MassHunter" mass calculator and get the multiple molecular formula matches and export these matches to excel (with their deviation). Ultimately I parse...

          algorithm in python

          The problem is:

          -given the number or students, number of weeks, and number of tables, write an algorithm that takes the students and places then at tables for (w) weeks, switching every week, so that the interaction between different students is maximized. As in, each students should not spend too many weeks with one specific student. the number of tables is always less than the number of students, and the number of students does not...

            Segmentation fault in determining closest pair

            I'm trying to code the closest pair algorithm...but when the distribution of points is too close, it is giving segmentation fault. My algorithm is right as for points sparsely placed it is giving same answer with bruteforce...th e problem is most probably when the line dividing points into two halves contain more than one point(not sure though) whose probability inc. with more and more points in picture. Here's my code

              How can I calculate the complexity of a c++ code?

              Calculate the complexity of the following C++ code fragment: [3]
              count = 0;
              for (i = 1; i <= n; i *= 2)
              for (j = 1; j <= i; j++)

              count++;
              Note: You are required to show all your workings.

                  Pattern Matching in C/C++

                  I've learned a programming language in C/C++. I want to make a program which try to compare two arrays (random chars)and notify the user about the differrents. The program have to notify both the subtitution and insertion/deletion.

                  Here are the examples :

                  array 1 : xxxxxxxxx...(as standard)
                  array 2 : xxxyxxxxx...

                  the program will notify that,

                    I am a student of Software Engineering. Today I asked this question to my teacher in class. But did not get any satisfactory answer

                    Can any one please give me some insight why should i learn this topic in my graduations.

                      Steganography algorithm in python?

                      Hi,

                      I'm developing a library to manage passwords and hide them in images. For now I'm using stepic, but this library only allows BMP images (easy to find info). I was wondering if there's any other steganography library in python. An implementation of F5 algorithm would be perfect! Any clues?
