Trying other methods
As we saw in the video, not being sure about what thresholding method to use isn't a problem. In fact, scikit-image provides us with a function to check multiple methods and see for ourselves what the best option is. It returns a figure comparing the outputs of different global thresholding methods.
Image loaded as
fruits_image.
You will apply this function to this image, matplotlib.pyplot has been loaded as plt. Remember that you can use try_all_threshold() to try multiple global algorithms.
This exercise is part of the course
Image Processing in Python
Exercise instructions
- Import the try all function.
- Import the rgb to gray convertor function.
- Turn the fruits image to grayscale.
- Use the try all method on the resulting grayscale image.
