- Let ABCD be the rectangular clipping window with A(20,20), B(90,20), C(90,70), D(20,70). Use Cohen Sutherland algorithm to clip line PQ with P(10,30) and Q(80,90)(Computer Graphics)Using the Cohen-Sutherland line clipping algorithm, clip the line PQ with coordinates P (-5, 3) and Q (15, 9) against a clipping rectangular window with coordinates (0, 0) and (10, 10) as lower left and upper right corner respectively. Also, find intersection points if any.Compare the number of arithmetic operations performed in the Cohen Sutherland and the Liang Barsky line clipping algorithm for several different line orientations relative to a clipping window.
- 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 0F00han object is in location (0,0), (1,0), (0,1) and (1,1). Write the new positions after shearing the object about x-direction. Take shear parameter along x-direction shx=4.Then apply reflection about the line x=0(the Y axis).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.
- 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 separatelyWrite a code that can be used to plot a 3D graph where x & y are between -5 to 5 and z is defined by the following equation. “z=4x4y - 3x3y2 + x”A friend would like you to build an “electronic eye” for use as a fake security device. Th e device consists of three lights lined up in a row, controlled by the outputs Left , Middle, and Right, which, if asserted, indicate that a light should be on. Only one light is on at a time, and the light “moves” from left to right and then from right to left , thus scaring away thieves who believe that the device is monitoring their activity. Draw the graphical representation for the finite-state machine used to specify the electronic eye. Note that the rate of the eye’s movement will be controlled by the clock speed (which should not be too great) and that there are essentially no inputs.
- A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”. Write a single…The implementation code explains how to use the label propagation algorithm. There can be a list of resolutions defined, but only the first one is used. If no resolution list is supplied, the number 1 is used as the default. Any other value can be used, but the desired value must be given in the resolution list.Write a pseudocode and draw a timeline diagram for the sliding window algorithm with SWA = RWS = 4 and SWS = 3 and RWS = 1 frames in the following two situations. Assume the receiver sends a duplicate acknowledgment if it does not receive the expected frame. For example, it sends DUPACK[2] when it expects to see Frame[2) but receives Frame[3] instead. Also, the receiver sends a cumulative acknowledgment after it receives all the outstanding frames. For example, it sends ACK (5) when it receives the lost frame Frame(2) after it already received Frame(3), Frame(4), and Frame[5]. Show the start timer and stop timer wherever necessary. Use a timeout interval of about 2 x RTT.
