摘要

提出了一种并行平滑机制

并基于该机制实现了构造DoG尺度空间的并行结构.在不影响匹配性能的情况下

与传统的结构相比

延迟线数量降低了84%

进而使得存储容量降低了90%左右.在131MHz的工作频率下

对于320×240的图像来说

完成高斯差分尺度空间的构造仅需要0.59ms.

Abstract

In order to reduce the memory requirement caused by line buffers

we proposed a parallel architecture based on a parallel smoothing scheme to construct DoG scale space.Compared with the conventional architecture

the number of line buffers is reduces by 84%

which leads to the memory requirement dropped by 90%

in the similar false positive rate.It only takes 0.59ms to construct DoG scale space for a 320×240image at 131MHz.
