今天,抽短暂时间实现了一个新的功能,那就是16位图像的读取以及伪彩色视觉效果增强。个人感觉各种语言还是C++好用,PY虽然很火,但是项目中执行效率是真的难受。 --->Today, a new feature has been briefly implemented, which is the ability to read 16-bit images and enhance false-color visuals.I personally feel that various languages are still good for C++,python is very popular, but the execution efficiency in the project is really uncomfortable. 如果你真的了解opencv等,你会发现,opencv默认读取的是8位图像数据,如果需要读取16位深度的图像,你需要进行相应的处理。你会奇怪位深度对于一个图像有什么用,位深度用于指定图像中的每个像素可以使用的颜色信息数量。每个像素使用的信息位数越多,可用的颜色就越多,颜色表现就更逼真。例如,位深度为 1 的图像的像素有两个可能的值:黑色和白色。位深度为 8 的图像有 28(即 256)个可能的值。位深度为 8 的灰度模式图像有 256 个可能的灰色值。RGB
