What is the step that is performed before color image processing in image processing? Wavelets and multi resolution processing Image enhancement Image restoration Image acquisition Q3. Which of the following step deals with tools for extracting image components those are useful in the representation and description of shape? Segmentation Representation & description Compression Morphological processing Q4. What role does the segmentation play in image processing? Deals with extracting attributes that result in some quantitative information of interest Deals with techniques for reducing the storage required saving an image, or the bandwidth required transmitting it Deals with partitioning an image into its constituent parts or objects Deals with property in which images are subdivided successively into smaller regions Q5. Which of the following measures are not used to describe a region? Mean and median of grey values Minimum and maximum of grey values Number of pixels alone Number of pixels above and below mean Q6. The technique of Enhancement that has a specified Histogram processed image as result, is called? Histogram Linearization Histogram Matching Histogram Equalization None of the mentioned Q7. In Histogram Matching or Specification, z = G-1[T(r)], r and z are gray level of input and output image and T & G are transformations, to confirm the single value and monotonous of G-1 what of the following is/are required? G must be strictly monotonic G must be strictly decreasing All of the mentioned None of the mentioned Q8. In 4-neighbours of a pixel p, how far are each of the neighbors located from p? One pixel apart Four pixels apart Alternating pixels None of the Mentioned Q9. Inverse transformation plays an important role in which of the following Histogram processing Techniques? a) b) c) d) Histogram Matching Histogram Equalization Histogram Linearization None of the mentioned Q10. If S is a subset of pixels, pixels p and q are said to be ____________ if there exists a path between them consisting of pixels entirely in S. ambiguous connected continuous none of the Mentioned Q11. If an image contains K disjoint regions, what does the union of all the regions represent? Background Foreground Outer Border Inner Border Q12. In terms of Sampling and Quantization, Zooming and Shrinking may be viewed as ___________ Oversampling for both Oversampling and Undersampling respectively Undersampling and Oversampling respectively Undersampling for both Q13. While Zooming, In order to perform gray-level assignment for any point in the overlay, we assign its gray level to the new pixel in the grid its closest pixel in the original image. What’s this method of gray-level assignment called? Neighbor Duplication Duplication Nearest neighbor Interpolation None of the mentioned Q14. A special case of nearest neighbor Interpolation that just duplicates the pixels the number of times to achieve the desired size, is known as ___________ Ridging Contouring Bilinear Interpolation Pixel Replication Q15. A pixel p at coordinates (x, y) has neighbors whose coordinates are given by: (x+1, y), (x-1, y), (x, y+1), (x, y-1). This set of pixels is called ____________ 4-neighbors of p Diagonal neighbors 8-neighbors None of the mentioned Q16. What is the set of pixels of 8-neighbors of pixel p at coordinates (x, y)? (x+1, y), (x-1, y), (x, y+1), (x, y-1), (x+2, y), (x-2, y), (x, y+2), (x, y-2) (x+1, y), (x-1, y), (x, y+1), (x, y-1), (x+1, y+1), (x+1, y-1), (x-1, y+1), (x-1, y-1) (x+1, y+1), (x+1, y-1), (x-1, y+1), (x-1, y-1), (x+2, y+2), (x+2, y-2), (x-2, y+2), (x-2, y-2) (x+2, y), (x-2, y), (x, y+2), (x, y-2), (x+2, y+2), (x+2, y-2), (x-2, y+2), (x-2, y-2) Q17. What is the unit of compactness of a region? Meter Meter2 No units Meter-1 Q18. What does the bilinear Interpolation do for gray-level assignment? Assign gray level to the new pixel using its right neighbor Assign gray level to the new pixel using its left neighbor Assign gray level to the new pixel using its four nearest neighbors Assign gray level to the new pixel using its eight nearest neighbors Q19. Row-column deletion method of Image Shrinking is an equivalent process to which method of Zooming? Bilinear Interpolation Contouring Pixel Replication There is no such equivalent process Q20. Image Shrinking has an undesirable feature, that is ____________ Aliasing effect False contouring effect Ridging effect Checkerboard effect 1 out of 4 Time is Up! Time's up Tagged with: MCQ
