使用 OpenCV 获得更好的性能? [英] Getting better performance using OpenCV?

问题描述

我需要实时处理，但是 OpenCV 的内部函数没有提供这个.我正在做手势识别，它几乎完美地工作，除了结果输出非常滞后和缓慢.我知道这不是因为我的算法，而是因为 OpenCV 的处理时间.我能做些什么来加快速度吗?

I need real time processing, but the internal functions of OpenCV are not providing this. I am doing hand gesture recognition, and it works almost perfectly, except for the fact that the resulting output is VERY laggy and slow. I know that this isn't because of my algorithm but the processing times of OpenCV. Is there anything I can do to speed it up?

Ps:我不想使用 IPP 库，所以请不要建议.我需要提高 OpenCV 本身的性能

Ps: I don't want to use the IPP libraries so please don't suggest that. I need increased performance from OpenCV itself

推荐答案

改进图像分析的传统技术:

Traditional techniques for improving image analysis:

1. 将图像缩小为单色样本.
2. 减少样本范围，例如从 8 位单色到 4 位单色.
3. 缩小图像的大小，例如1024x1924 到 64x64.
4. 降低帧速率，例如 60fps 到 5fps.
5. 执行更高级别的函数以猜测目标区域的位置，例如较低的分辨率，然后对裁剪后的输出执行常规分析，例如在确定手势之前执行图像识别以定位手.
