An 8-bit image has a perfectly normalized histogram. Suppose that each pixel value is ANDed with 1000 0000 , and is set to white if the result of ANDing is non-zero, otherwise is set to black if the result is zero. What is the normalized number of black pixels in the output image? Write the number with 2 decimal points in the box below.

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
Write a program to reduce the number of gray levels L in a PGM image from L=256 to: (i) L=128,(ii) L=32, (iii) L=8, and (iv) L=2. Show your results using the “lenna” and “peppers” images. Forcomparison purposes, subsample the gray-levels to better visualize the quantized images (e.g.,if L=128, you can use 0, 2, 4, …, 254 with Q=255 in the PGM file instead of 0, 1, 2, …, 127 withQ=127; similarly, if L=2, you can use 0, 127 with Q=255 instead of 0, 1 with Q=1).
Please using python to implement the following task. Given a RGB color image ‘test.jpg’ noised by salt and pepper noise, first choose a good filter to remove noise on each channel, then based on the gray image of this new RGB color image, use canny edge detection to get edges. Finally show the original image and its edge image.

Computer Science For an image represented by a given large 3d numpy array, use numpy to get a neighborhood filter using the mean of the pixels. For example, look through each of the image’s 3×3 window of pixels and replace outlier pixels with the mean value of the others in the 3×3 window. Set the resulting pixel value to be the mean value of a pixel and its eight neighbors. For pixels on an edge, use the mean value of the pixel and its five neighbors. For pixels on corners, use the mean value of the pixel and its three neighbors. If you loop over every pixel then you must store your input and output arrays separately
Computer Science Let C be a black circular disk in front of a white background. The circular disk is parallel to the image plane. This disk is projected on the image plane through a pinhole. What is the shape of the disk’s projection on the image plane? [Hint: A circular disk parallel to the image plane is described algebraically as all 3D points [X,Y,Z]T with (X-X0) 2 +(Y-Y0) 2 =R2 , Z=Z0, where [X0,Y0,Z0] T is the center of the disk and R is its radius.]
Based on the sample output in the provided image and given below, With the use of python, write a program that takes the x-y coordinates of a point in the Cartesian plane and displays a message telling either an axis on which the point lies or the quadrant in which it is found. Sample Output: (-1.0, -2.5) is in quadrant III (0.0, 4.8) is on the y axis

Consider two traffic lights in a junction that each one has a 7-segment display to show the remaining time. The traffic lights are working as follows: State1: Traffic light 1=GREEN Traffic light 2=RED for 10 seconds,State2: Traffic light 1=YELLOW Traffic light 2=YELLOW for 2 seconds,State3: Traffic light 1=RED Traffic light 2=GREEN for 6 seconds,GOTO State1 During each step, the amount of remaining time should be displayed on the 7-segment and it should be updated every one second. For example in State 1, the display shows 9, then after a second it shows 8, and ... finally, it shows 0 for one second, and the control moves to State 2Write an 8051 assembly program according to the Edsim51 configuration, LED 0, LED1 and LED 2 construct the first traffic light, and LED 3, LED 4, and LED 5 can be used for the 2nd traffic light. Assume that the lookup table for 7segment exists on memory at address 0F00h
