Moving on to image processing, OpenCV allows us to perform multiple operations on an image, but for that we need to read the image file as input, then we can perform the desired operation and save it.
Let`s see a simple operation. to read the image file using the OpenCV library and then save it.
– & gt; imread (Location_of_image, integer): The second parameter is an integer for changing the color of image. -1 To read image Unchanged and 0 To read image in gray scale.
– & gt; imwrite (Name_after_save, variable_containing_read_image)
– & gt; waitKey (0): After execution will keep the window open till a key is pressed
– & gt; destroyAllWindow (): It will close all the windows that were opened during the program run.
Below is the Python implementation:
