示例1: compare
void compare(const std::vector<cv::Point>& locations)
{
// skip block_hists check
int rows, cols;
f.read((char*)&rows, sizeof(rows));
f.read((char*)&cols, sizeof(cols));
for (int i = 0; i < rows; ++i)
{
for (int j = 0; j < cols; ++j)
{
float val;
f.read((char*)&val, sizeof(val));
}
}
int nlocations;
f.read((char*)&nlocations, sizeof(nlocations));
ASSERT_EQ(nlocations, static_cast<int>(locations.size()));
for (int i = 0; i < nlocations; ++i)
{
cv::Point location;
f.read((char*)&location, sizeof(location));
ASSERT_EQ(location, locations[i]);
}
