Nine colour model (NCM).The H component
has some exceptional points in close to the V component,
which RGB minor changes will cause larger changes in
the H component.The capacity to distinguish colour of H
and S components is smaller when the brightness near the
white or black areas.To avoid the shortcoming of HSV
colour space,we inducted a new colour space to access
seed colour,i.e.,nine colour model.Given the transformed
h and s in Eqs.,the transformation to
NCM can be achieved by the following equations
where the value of nh is 1 to 9,which represents black,
white,red,orange,yellow,green,cyan,blue and magenta,
respectively
Colour recognition methods
The key to identify rapeseed seed colour is not the appropriate
colour space,but the correct recognition method
Common method.Given the transformed h,s
and v in Eqs.(2)-(4),the recognition to rapeseed seeds
colour can be achieved by the following methods:
For single seed,we firstly calculated the mean of h,s and
v of each pixel of a seed in an image.Then those mean
values were transformed into NCM colour space.
For an image or a sample,we also calculated the mean of
h,s and v of each seed.And those mean values would be
transformed into NCM colour space

九色模型(NCM).色调部分跟色值部分紧密靠在一起时有些独特的色点,色值部分的微小变化可以造成色调部分的更大变化.当光亮靠近白色或黑色区域时,区分色调部分和色强部分的能力变得更小了.为了避免HSV色彩空间的亏损,我们殖入一个新的颜色空间到种源色里去,即九色模式.鉴于在均衡器里面已经转换了的色调和色强,下列方程式可以得到转换为九色模型的值.
n个色调的值是1到9,分别代表黑色、白色、红色、橙色、黄色、绿色、青色、蓝色和洋红.
色彩识别方法
识别油菜籽种色空间的关键是不得当的颜色空间,但是正确的识别方法
常见方法.鉴于在均衡器中色调、色强和色值进行了转换,(2)-(4),通过下列方法可以识别油菜籽的种源色：对于单个种子,我们首先计算图像中某颗种子像素的色调、色强、色值的平均值.然后这些平均值就转化成九色模型的色彩空间.
对于图像或样品,我们同样可以计算出每颗种子的的色调、色情、色值的平均值.这些这些平均值就转化成九色模型的色彩空间.
