Image Contrast Adjusting Filter

Images captured in dim light mostly not have a much better contrast so an (Image Contrast Adjusting filter) filter helps accordingly to adjusts and increase its contrast and hence we are having a better version of the image. Hence this filter helps to get a high contrast image.

Libraries used

Firstly import the following python libraries

• Matplotlib,
• NumPy
• PIL Save the image and your code in the same folder Run the python code

Detailed explanation of the method used

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