查阅函数imshow()的文档,发现有下面这段说明:
If the image is 8-bit unsigned, it is displayed as is.
If the image is 16-bit unsigned or 32-bit integer, the pixels are divided by 256. That is, the value range [0,255*256] is mapped to [0,255].
If the image is 32-bit floating-point, the pixel values are multiplied by 255. That is, the value range [0,1] is mapped to [0,255].
上面这段话具体的翻译请大家参看页面:https://www.hhai.cc/thread-86-1-1.html
本文详细介绍了imshow函数在处理不同类型的图像数据时的具体显示原理。针对8位无符号整数、16位无符号整数或32位整数以及32位浮点数图像数据的不同处理方式进行了阐述。
