Fixing n_candidates_ instead of assert in keyframe_graph_detector.cpp

[diogorolo]

Hi,

Sometimes when you have a low amout of keyframes and you ask to generate the graph, the program exits due to: assert(ncandidates <= size);

An alternative would be(@@ -349,7 +349,10 @@):

// check for validity of n_candidates argument int size = matchmatrix.rows;

if(ncandidates > size) { ncandidates = size; } assert(ncandidates <= size);
