کر ويم يم
compute the lengths of the shortest 4-, 8-, and m- path between p and 0. If a
particular path does not exist between these two points, explain why?
PART C
Answer any two full questions, each carries 9 marks.
Write short note on median filters.
Explain homomorphic filtering.
Define histogram. How histogram is generated for an image. Sketch the
histograms of dark image, light image, low-contrast image and high contrast
image.
How negative of an image is obtained?
Explain about smoothing frequency domain filters and sharpening frequency
domain filters.
