C++ (Cpp) mReadBits Examples

Example #1

File: Chilitags.cpp Project: kubat/chilitags

std::map<int, Quad> find(const cv::Mat &inputImage){
    auto greyscaleImage = mEnsureGreyscale(inputImage);

    std::map<int, Quad> tags;

    for (const auto & quad : mFindQuads(greyscaleImage)) {
        auto refinedQuad = mRefine(greyscaleImage, quad);
        auto tag = mDecode(mReadBits(greyscaleImage, refinedQuad), refinedQuad);
        if (tag.first != Decode::INVALID_TAG) tags[tag.first] = tag.second;
        else {
            tag = mDecode(mReadBits(greyscaleImage, quad), quad);
            if (tag.first != Decode::INVALID_TAG) tags[tag.first] = tag.second;
        }
    }
    return mFilter(tags);
};
