Bitwise image python

WebBitwise operators don’t work on floating point images. Logical Operators # Logical operators like and, or, and not work on entire images, rather than individual pixels. An empty image (all pixels zero) is treated as false. All other images are treated as true. WebPython’s bitwise operators let you manipulate those individual bits of data at the most granular level. You can use bitwise operators to implement algorithms such as …
