Image Processing and Pattern Recognition Question Set 2018
1) Explain how you can convert an analog image into a digital 2 image. Also discuss the various applications and problems associated with the digital image processing in brief. How many images of size 1400x1000 with 256 gray levels can be stored in a 1024 MB storage space? 2) Define Discrete Cosine Transform (DCT). How do you determine Sequency order from the natural order in Hadamard transform? Explain it with a suitable example. 3) What is a Fourier Transform and howÂ can you apply it in the digital image processing? Explain the different properties of the Fourier Transform. 4) Explain the bit plane slicing techniques for the purpose of image enhancement. Explain the median filter along with suitable algorithm for its implementation. 5) What is a minimum filter? Given the following gray levelÂ Â histogram of an image. Compute the gray levels after histogram equalization.
a) Ideal High Pass Frequency domain filter
b) Template Matching
c) Pattern Recognition and Applications
