arm-neon-opencv's Introduction

a few operators of opencv implement by arm neon

测试

测试脚本:

./run.sh

测试main函数 : src/test/src/test_main.cpp，选择测试vacv函数
测试类实现 : src/test/src/impl
测试参数 : src/test/src/profile/cv_profile.cpp

_k_test_times    :  测试次数    
k_log_batch_size :  输出日志间隔次数

测试实现

测试基于opencv原生算子，对相同图像的相同操作，
与vacv对应算子的输出结果与运算效率进行对比。
输出对比使用余弦相似度。
