如何从图像材料中发现颜色?
原标题:how to detect colour from an image matlab?

we are doing a mat lab based robotics project.which actually sorts objects based on its color so we need an algorithm to detect specific color from the image captured from a camera using mat lab. it will be a great help if some one can help me with it.its the video of the project

In response to Amro s answer:

“具有相同湿度但视相异的平方”/

以上五平方米的湿度值在特别安全区空间相同。 胡伊人的选择是有益的,但你也希望对饱和和价值施加一些限制。

HSV允许你以更人道的方式描述肤色,但你仍然需要看看所有三个价值观。

问题回答

作为一个起点,我将使用加固空间和埃利斯群岛规范,以检测一个钢材是否具有某种肤色。 典型的情况是,你有3个六种数值:[red Green Blue]。 你们还有3种定义目标肤色的数值:[255 0]。 调整这两种病媒之间的电子教育规范,并适用决定门槛,对你的颜色进行分类。

最后,你想要摆脱污染因素(即它是一种光明的红色还是黑暗的红色)。 您可以转而使用HSV空间,并使用相同的H值规范。 也可使用<代码>[红/绿色蓝/绿色]病媒。 在此之前,由于各司(也存在于冲积变中)往往增加噪音,因此对图像采用低发过滤器。

你可能希望改用特别安全局的彩色空间,并根据湿法的数值探测肤色。 MATLAB提供RGB2HSV功能。

这里有

要想获得一个单一的彩色面罩,首先要利用加固2gray来转换成彩色图像。 还从“彩色”图像中提取出所希望的彩色粉(例如,为了获得红平原,可提供增益(:1))。 减去特定平面图。
