+ Here is the call graph for this function:

std::vector< std::vector< int > > ActsExamples::HoughTransformSeeder::getComboIndices ( std::vector< size_t > &  sizes) const
private

Given a list of sizes (of arrays), generates a list of all combinations of indices to index one element from each array.

For example, given [2 3], generates [(0 0) (1 0) (0 1) (1 1) (0 2) (1 2)].

This basically amounts to a positional number system of where each digit has its own base. The number of digits is sizes.size(), and the base of digit i is sizes[i]. Then all combinations can be uniquely represented just by counting from [0, nCombs).

For a decimal number like 1357, you get the thousands digit with n / 1000 = n / (10 * 10 * 10). So here, you get the 0th digit with n / (base_1 * base_2 * base_3);
