Q.1. Describe the region based segmentation. Apply the region splitting on following image. Assume the threshold value less than or equal to three.

Q.2. Describe any one depth algorithm in detail. Q.3. What do you mean by boundary descriptor? Also find the shape no of the following figure.

Q.4. Discuss parametric and non-parametric methods in optimal thresholding method.Q.5. How many degrees of freedom are there in a plane projective transformation ? Name the properties preserve under such transformation.Q.6. Explain Image registration. Discuss various edge detectors in detail. Q.7. Explain bit-plane slicing for a digital image. Also explain the benefits of Image subtraction operation.Q.8. Differentiate segmentation and quantization. Also explain region based segmentation.Q.9. Q.10. Discuss the concept of Homomorphism filtering with suitable example .Q.11. Show that the Fourier transformation and its inverse are linear process.Q.12. Explain the correspondence between filtering in the spatial and frequency domains in details .Q.13. What is smoothing and Sharpening Spatial Filter ? Explain in detail .Q.14. Explain the functioning of CCD line scan sensor and CCD area sensor in brief .Q.15. What are the basic filtering in the frequency domain ? Explain in detailQ.16. Gray level histogram of an image is given below :Gray Level01234567
