Simd库是一个免费的开源图像处理和机器学习库,专为C和C++程序员设计。 它为图像处理提供了许多有用的高性能算法,例如:像素格式转换,图像缩放和过滤,从图像中提取统计信息,运动检测,对象检测(HAAR和LBP分类器级联)和分类,神经网络。 官网Simd Library (ermig1979.github.io),可以下载编译,函数含义可以参考文档 该库...
Parasail is a SIMD C (C99) library containing implementations of the Smith-Waterman (local), Needleman-Wunsch (global), and semi-global pairwise sequence alignment algorithms. Here, semi-global means insertions before the start or after the end of either the query or target sequence are not pe...
Opal (ex Swimd) is SIMD C/C++ library for massive optimal sequence alignment. Opal is implemented mainly by Rognes's "Faster Smith-Waterman database searches with inter-sequence SIMD parallelisation". Main difference is that Opal offers support for AVX2 and 4 alignment modes instead of just ...
