该博客讨论了如何在Java中实现一个功能，该功能读取图像并检测红色、蓝色、绿色、黄色等颜色的存在，以进行卫星图像分析。作者寻求避免使用大量逻辑语句检查每个像素的RGB值，而希望找到更简洁的方法。文中提供了一个通过转换RGB到HSB颜色空间来判断颜色接近度的解决方案。

Im looking to implement a feature in Java which reads an image and is able to detect where there are shades of red, blue, green, yellow, etc. as part of a satellite image analysis program. So for example in a standard satellite image, blue would be water so I would like the program to read how many pixels are blue and then it could say x% of the image is water.

I know it would be possible using a whole load of logic statements by reading the RGB value of each pixel but is there an easier way to do this? Otherwise there will be hundreds of if statements which is going to take a long time to write but also a long time to perform. Ideally id like something like this:

if (pixelValue = red) {

redCounter++;

}

Which is obviously very simple but it would save having to go through every single possible RGB combination for red, blue, green, yellow, purple, etc. which ar
