WebJul 2, 2024 · I am trying to convert from float/double to fixed point notation, for instance let's use the number x = 0.39 as input.. I would like to convert x into its unsigned 16 bits fixed-point counterpart, to do so in C++ I am accustomed to use the expression xFixedPoint = round(x*2^(16)), this will make that the fixed point version of 0.39 is 25559.. However, I … Web关于sift算法的原理有很多文档，本来想整理到BLOG，但是考虑到排版比较麻烦，就不弄了。把opencv里面的sift源码详细注释了一下，把相关函数重新整合到SIFT的类里面，这样就可以用这个类而不用opencv的sift接口来提取特征点，用此方法提取特征点的速度上也有很明显的提升，说明OpenCV用来做具体的 ...
