- bIllustrate colour models. Explain in detail how colour mode ls are converted to each other
- aDerive the expression of sec ond order derivative of image sharpening i.e. Laplacian filter
- bAnalyze the impact if the arithmetic mean filter is applied to an image again and again? What will happen if we use the median filter instead?
- aAnalyze the concept and e xpression of restored image using minimum mean square approach.? What are the advantages of a Wiener filter over an inverse filter?
- bIllustrate different resto ration filters in frequency domain. What is the significance of Notch filter in image restoration?
- aDiscuss the following: (i) Border Tracing (ii) Edge Relaxation
- bDiscuss robert, sobel, prewitt operator of edge detection. For the given image write down the 8 chain code & find shape number of it
- aDiscuss why do we focus on boundary. Which descriptor is us ed to describe holes and connected components of the region?
- bThe characters a to h have the set of frequencies based on the first 8 Fibonacci numbers as follows
