cmp_thresh decides whether an edge should be formed between two nodes. A higher value will let fewer edges appear in the graph. If the magnitude of input correspondence is small (e.g., 500) or the inlier ratio is low (e.g., 1%), the value should be smaller (0.9). If the size of correspondences is quite large or the inlier ratio is high, it should be larger (e.g., 0.999).
