Increasing the contrast of an image to get a better version of it.

Used some of the python libraries to convert an image into a high contrast image.

• Matplotlib,
• IPython.display
• NumPy
• CV2

Steps:

• Imported the required libraries ( Numpy, Matplotlib, PIL, IPython.display)
• Read the input image using Image using cv2 library

Methods applied

• Converted the image into an array and then flatten it making it a 1d array
• Count the number of occurance of each pixel in the image and hence getting an array of frequency count of each pixels
• Then making cdf from the frequency count list
• Normalizing the cdf
• Converting the cdf shape into the shape of given image
• Finally converted the image into contrast adjusted image
