我需要将黑色点数按图像计算(黑点的百分比没有,而是计数)。 任何人都能够建议一个步骤明智的程序,在图像操纵中用来计算点数。
Objective : Count black spots in an image
What I ve done till now : 1. Converted image to grayscale 2. Read the pixels for their intensity values 3. I have set a threshold to find darker areas
Other implementations: 1. Gaussian blur 2. Histogram equalisations
What i have browsed : Flood fill algorithms, Water shed algorithms
非常感谢。
你们首先应当“标签”图像,然后计算一下你发现的标签数目。

- (见;the wikipedia article ;或tts page ,用于更多贴标签信息。 http://crd.lbl.gov/%7Ekewu/ps/LBNL-59102.pdf
在贴标签之后,贴上标签的数量(你甚至可以贴上标签的标签),你有
下一个步骤是界定黑点:将你的输入形象转化为光线图像(通过将图像转换为HSL,并例如使用采矿计划),然后适用门槛值。 如果对你的输入形象的低估甚至不一样,你可能需要更好的门槛算法(a Adaptation limit。
如你想要用双亲形象标识算法贴上黑点(Blobs)的标签。 。
