Q1) True or False Check the correctness of the following statements. 1) In computer generated images, there is a need for a physical energy source. 2) Digital image processing fails to justify psychologically perceived brightness issues. 3) Interpixel redundancy implies that pixel values are not correlated. 4) Bit-plane slicing is a technique that highlights the contribution made by a specific bit and each biplane is a color image. 5) Piecewise-linear transformation functions can be used to slice a specific range of gray levels. 6) Histogram equalization stretches the histogram so that it is spread from 0 to max. 7) Coding redundancy happens when the length of the code words is larger than needed. 8) The human eye is more sensitive to the lower frequencies than to the higher frequencies in the visual spectrum. 9) Skeletonization is a morphological operation that deletes black foreground pixels iteratively layer by layer until one-pixel width skeleton is obtained. 10) Gradient operator providing both differencing and a smooth effect and slightly superior noise reduction characteristics.
