What do you understand from the term Organizational Aspects of System Life Cycles? Explain. Illustrate out the concept of system transition strategy.
A company wants to produce a grayscale display with pixels so small that a human will be not able to see the individual pixels under normal viewing conditions.
Suppose now that all of the objects are perfect reflectors (in addition to having ambient, diffuse and specular reflection).
In image compression we utilize three different methods to compress pixel data:
Describe how straight lines can be employed to draw the Bezier cubic curves.
Explain the A-buffer polygon scan conversion algorithm by using 44 sub-pixels in all pixels.
Illustrate an algorithm (other than thresholding) that will convert a grayscale image (8 bits per pixel) to a bi-level black and white image (1 bit per pixel), with similar number of pixels, while r
Describe why homogeneous coordinates are employed for handling the geometric transformations.
Compare and contrast the ray tracing and z-buffer algorithms.
Derive the conditions essential to make sure that two cubic Bezier curves join with C1-continuity.
Explain an algorithm for transforming a grayscale image to a bi-level (black and white) image while retaining as good a quality as possible.
Explain an algorithm which transforms a grayscale image into a black and white image by using half toning. Suppose that the black and white image has eight times the resolution of the grayscale imag
Explain the modifications needed to your algorithm in part (3) to make it draw the outline of a circle centered at arbitrary non-integer coordinates and of non-integer radius.
Describe each method; describe the manner in which it helps us to compress the image, and explain how the method is implemented in the baseline JPEG compression method.
Describe the merits and demerits of using nearest-neighbor interpolation compared with bilinear interpolation.
Explain how Douglas and Pucker's algorithm can be used to eliminate superfluous points. You might use the algorithm from part first.
One method of anti-aliasing is to sample at high resolution, n x n higher than the final image, and then to average each block of n x n pixels to give a single pixel value. Describe the merits and d
Describe the A-buffer polygon scan conversion algorithm by using 44 sub-pixels for each pixel.
What additional hardware might be helpful to help with producing the intermediate coordinates from the end-points of lines?
You are writing a code for a new graphics card which is software programmable, instead of having the algorithms embedded in the hardware. You wish to write a fast triangle-drawing program to test th
Describe the Walsh-Hadamard transform on a one-dimensional array of 4 grayscale values.
How this line-drawing algorithm would be used to draw Bezier curves in three dimensions?
Explain, in detail, an algorithm to execute error diffusion on a grayscale image.
Consider the joint between the two cubic Bezier curves. Define and prove the constraints on their control points to make sure:
Draw either the first eight one-dimensional Haar basis functions or the first eight one-dimensional Walsh-Hadamard basis functions.
