问题描述

我遇到的问题是如何识别图像中的某些图案。

图像是纯白色的纸张图像，四个角落的图案是黑色的。
我想识别图像上的黑色图案？

我在网上冲浪很多，发现opencv作为答案。但没有提供任何描述如何使用opencv来实现所需功能。

请帮助我提供一些编码观点或提供一些我应该提供的链接跟随或任何我应该用来实现此功能的开源库的名称。
模式的图像如下： -

图像由纯白色背景和角落中的四个黑色图案组成。我需要识别所有四个角落中的这些黑色图案然后处理图像。一个角落以椭圆形显示突出显示它。

任何建议都将受到高度赞赏。

提前致谢！

I am stuck with a problem that is how to recognize some patterns in image.

the image is the image of paper which is pure white and the patterns are in four corners are in black. I want to recognize the black patterns on the image?

I surf a lot on the net and found that the opencv as a answer. but there is nothing provided that describe how to use opencv in order to achieve the required feature.

Please help me with some coding point of view or provide some link which I should follow or any name of any open source library which I should use to achieve this feature. The image for pattern is below:-

The image consist of pure white background and four black patterns in the corner.I need to recognize these black patterns in the all four corners all then process the image.One corner shown in oval to highlight it.

Any suggestions will be highly appreciated.

Thanks in advance!
