Question
Chapter 10, Problem 29CRP
Program Plan Intro
Hidden surface problem:
- In the pictures with non-transparent objects, the objects cannot be viewed that are behind from objects nearer to eye.
- These hidden surfaces are to be removed for getting realistic screen image.
- The removal of such surfaces is known as hidden-surface problem.
- The methods used for removing hidden surface problem includes:
- Object space method:
- It is executed in physical coordinate system.
- Image space method:
- It is executed in screen coordinate system.
- Object space method:
- To display a 3D object on 2D screen, the parts visible from chosen viewing point are to be identified.

Please write python codes to smooth an image by using median filter and Bilateral filter separately.
You should give your codes, the input image and its outputs.
Please use the Python languageUse filters for any image using kernel (filter) matrices. It should be done using loops (you can only use the image processing libraries to open or read the image). Apply these filters to an image you prefer with Python. Provide the outputs.
The issue: You are programming a graphics filter that filters each individual image. Each pixel is described as a triplet of real values, R, G, and B, each ranging from 0 to 255.For the filtering methods to function properly, real numbers must be used. However, after looking into the programme, you find that they simply want two digits of precision. Any extra digits are just unnecessary.
