Let's add some impact and contrast
Have you ever wanted to enhance the contrast of your photos so that they appear more dramatic?
In this exercise, you'll increase the contrast of a cup of coffee. Something you could share with your friends on social media. Don't forget to use #ImageProcessingDatacamp as hashtag!
Even though this is not our Sunday morning coffee cup, you can still apply the same methods to any of our photos.
A function called show_image(), that displays an image using Matplotlib, has already been defined. It has the arguments image and title, with title being 'Original' by default.

Image Processing in Python
Anleitung zur Übung
- Import the module that includes the Contrast Limited Adaptive Histogram Equalization (CLAHE) function.
- Obtain the image you'll work on, with a cup of coffee in it, from the module that holds all the images for testing purposes.
- From the previously imported module, call the function to apply the adaptive equalization method on the original image and set the clip limit to 0.03.
