Description

cv::SURF::operator() does not clear the input keypoint and descriptor vectors when new features are extracted.

Example:
function f(){
static cv::SURF surf_detector(400);
static vector<cv::KeyPoint> keys;
static vector<float> descs;
cv::Mat im = ...;
surf_detector(im, cv::Mat(), keys, descs);
...
}

Vectors keys and descs grow after each call to the function. This behaviour (which also happens in version 2.4.0) is not the same as in version 2.3.1, where vectors were cleared when calling ::operator().
