- Given the 3-bit 4x4 pixels image f(x,y) below, rescale the range of pixel values of f(x,y) so that they can be represented by 2 bits. What is the resulting image?Suppose a line segment starts at (x0, y0) and ends at (x1, y1) where, x0, y0, x1 and y1 are sequentially the first, second, third and fourth pair of digits from the left in your student ID. STUDENT ID: 21341040 Q:- Simulate the midpoint line drawing algorithm to find the first four intermediary pixels of this line after (x0, y0); or, all of them if the line reaches (x1, y1) in less than four pixels.Fix a marker on a wall or a flat vertical surface. From a distance D, keeping the camera stationed static (not handheld and mounted on a tripod or placed on a flat surface), capture an image such that the marker is registered. Then translate the camera by T units along the axis parallel to the ground (horizontal) and then capture another image, with the marker being registered. Compute D using disparity based depth estimation in stereo-vision theory
- If we use straight RGB value coding with 10 bits per primary color, how many colors are there for each pixel? There are several subfields in the topic of computer graphics.Converting an image to grayscale simplifies the algorithm and reduces computational requirements prior to extracting the image features. he total bits per pixel (bpp) for this image is 24. This is because for each primary colour (red, green, and blue) there are 8 bits per primary colour, and since there are 3 primary colours, 8 bits x 3 primary colours = 24 bpp. To calculate the size of the image file in bytes, we need to multiply the number of pixels (300 x 400 = 120,000 pixels) by the bpp (24 bits). 120,000 pixels x 24 bits = 2,880,000 bits To convert bits to bytes, divide the number of bits by 8 (2,880,000 bits / 8 = 360,000 bytes). Therefore, the size of the image file in bytes is 360,000. If the digital image above is converted to grayscale with 8 bpp, calculate the size of this grayscale image file in bytes with disregard to the image compression type. Provide a short explanation on the calculation."""You are given an n x n 2D mat representing an image. Rotate the image by 90 degrees (clockwise).

- Calculate 5 pixels of the straight line from (x0,y0,p0) to (x4,y4,p4), using the Bresenham Straight Line Algorithm, if (Xbegin, Ybegin) = (-20, 16) and (Xend, Yend) = (-5, 38)Given: ∀x [p(x) → q(x)]∀x[p(x) → (∀y w(y))]∀x ∀y [(q(x) ∧ w(y)) → s(x)] p(MARY) Show s(MARY) using resolution.Please help computer graphics question Let Z be the set of real integers and R the set of real numbers. The sampling process may be viewed as partitioning the x-y plane into a grid, with the central coordinates of each grid being from the Cartesian product Z2, that is a set of all ordered pairs (zi, zj), with zi and zj being integers from Z. Then, f(x, y) is a digital image if (x, y) are integers from Z2 and f is a function that assigns a gray-level value (that is, a real number from the set R) to each distinct coordinate pair (x, y). What happens to the digital image if the gray levels also are integers? a) The Digital image then becomes a 2-D function whose coordinates and amplitude values are integers b) The Digital image then becomes a 1-D function whose coordinates and amplitude values are integers c) The gray level can never be integer d) None of the mentioned
