增强现实的颜色/形状检测机制
是否存在一种非常基本的颜色/形状检测机制，通过该机制可以检测网络摄像头馈送中的特定颜色或形状？想要使用颜色/或形状作为 AR 应用程序的符号标记。 虽然理想的情况是 NFT ，但我不太擅长编码，也没有 OpenCV 经验（在之前的讨论中读过很多相关内容）。到目前为止，仅使用 SLAR 工具包，并且仅提供基本功能黑白标记检测 而且更容易使用的 NFT 库并不是免费软件：/
任何将上述检测例程集成到 .Net/Flash 环境中的指南都会有很大帮助。
Is there a very basic color/shape detection mechanism through which one could detect a specific color or a shape in a webcam feed? Wanted to use the color/or shape as a symbolic marker for an AR application.
Though the ideal case would be a NFT , but i am not much of coder and have no experience in OpenCV( have read a lot about it in previous discussions here).Have worked so far with the SLAR tooolkit only and that offers only the basic b/w marker detection
And the more easily useable NFT libraries are , well, not freeware :/
Any guidance to integrate the abovementioned detection routines in a .Net/Flash environment would be of great help.

颜色检测非常简单：获取视频流图像，使用 RGB 值作为向量（如 RGB = [0,255,0] = green）将它们转换为二进制图像，并将给定距离内的其他向量设置为正命中。这是最简单的计算机视觉形式之一，一些早期基于 CV 的 PS2 游戏涉及检测颜色鲜艳的道具。
这是我最喜欢的关于形状识别的论文 - 如果您想检测简单的 2D 轮廓在平坦的表面上，这是一项很棒的技术。
我既不是 .Net 也不是 Flash 程序员，因此我无法提供任何帮助。
Color detection is very easy: take your videostream images, convert them to binary images by using the RGB value as a vector (like RGB = [0,255,0] = green), and setting other vectors within a given distance as positive hits. This is one of the easiest forms of computer vision, and a couple of early CV-based PS2 games involved detecting brightly colored props.
This is my favorite paper on shape recognition - if you want to detect simple 2D outlines on flat surfaces, this is a great technique.
I'm neither a .Net or a Flash programmer, so I can't offer any help there.
