The compass gradient operators of size 3x3 are designed to measure gradients of edges oriented in eight directions: E, NE, N, NW, W, SW, S, and SE. i) Give the form of these eight operators using coefficients valued 0, 1 or – 1. ii) Specify the gradient vector direction of each mask, keeping in mind that the gradient direction is orthogonal to the edge direction.
Correct answer will be upvoted else downvoted. Computer science. You and your companions live in n houses. Each house is situated on a 2D plane, in a point with integer organizes. There may be various houses situated in a similar point. The chairman of the city is requesting you for places for the structure from the Eastern show. You need to track down the number of spots (focuses with integer arranges), so the outline distance from every one of the houses to the show is insignificant. The display can be inherent a similar point as some house. The distance between two focuses (x1,y1) and (x2,y2) is |x1−x2|+|y1−y2|, where |x| is the outright worth of x. Input First line contains a solitary integer t (1≤t≤1000) — the number of experiments. The principal line of each experiment contains a solitary integer n (1≤n≤1000). Next n lines portray the places of the houses (xi,yi) (0≤xi,yi≤109). It's reliable that the amount of everything n doesn't surpass 1000. Output For…
Create a square matrix in matlab that has ones in the first row and first column, and whose remaining elements are the sum of two elements: the element above and the element to the left. Your program should be able to make a matrix of any size. Do this exercise using a loop (for or while) and using break/continue functions as needed.
I see now how the histogram works, but the issue I'm having is if I put in the number 3 it only shows * (1 astrick) and I need it to match the index correctly.
link to MINST code: https://www.dropbox.com/s/i21pedejv0sknnq/MINST.pdf?dl=0 1) Add a confusion matrix to the MNIST code example from the link provided. Set the epochs parameter to 5. Explain which entry of the matrix yields the number of ones (the number 1) that are falsely recognized as eights (the number 8). (If you use indices in your explanation, use the Python index notation, i.e., start at zero.) Run your code a few times. Is the confusion matrix always the same? Briefly explain.
Implement the plus_one function as directed in the comment above the function. If the directions are unclear, run the code, and look at the expected answer for a few inputs. This function should work regardless of whether x is negative or not, and you should not use the ‘+’ symbol anywhere in your solution, nor any constants. To find the solution to this task, you should use your understanding of integer operations to find a way to add 1. Hint: consider what happens when you do -x. Could you use it with other operations to get x+1?. #include <stdio.h>#include <stdbool.h>#include <stdlib.h> // BEGIN STRINGBUILDER IMPLEMENTATION // This code is a very rudimentary stringbuilder-like implementation// To create a new stringbuilder, use the following line of code//// stringbuilder sb = new_sb();//// If you want to append a character to the stringbuilder, use the// following line of code.

Q3. The given coordinates are (0,0), (0,2),(2,0),(2,2) for representing a rectangle/square ,you are expected to find x-shearing where shearing parameter towards x-direction is 2 units. Also you are expected to find y-shearing if the shearing parameter towards y-direction is 3 units. Draw the objects before and after shearing. (Note: You are expected to use matrix representation in calculating the required values)
Study the scenario and complete the question(s) that follow: Suppose that there are items that need to be processed, in the order which they are provided. There are times that some of the packages need to be chosen to be processed first Source: Mbela, K.

You need to change this grouping so all components in it are equivalent (I. e. it contains a few events of a similar component). To accomplish this, you pick some integer x that happens to some extent once in a, and afterward play out the accompanying activity quite a few times (perhaps zero): pick some portion [l,r] of the arrangement and eliminate it. Yet, there is one special case: you are not permitted to pick a fragment that contains x. All the more officially, you pick some adjoining aftereffect [al,al+1,… ,ar] to such an extent that ai≠x if l≤i≤r, and eliminate it. After expulsion, the numbering of components to one side of the eliminated portion changes: the component that was the (r+1)- th is presently l-th, the component that was (r+2)- th is currently (l+1)- th, etc (I. e. the leftover arrangement simply falls). Note that you can not change x after you picked it. For instance, assume n=6,…

The grouping may contain duplicates (for example a few components can be equal). Track down the number of tuples of m=3 components with the end goal that the maximum number in the tuple varies from the base by close to k=2. Formally, you want to view as the number of triples of lists i<j<z with the end goal that max(ai,aj,az)−min(ai,aj,az)≤2. For example, on the off chance that n=4 and a=[1,2,4,3], there are two such triples (i=1,j=2,z=4 and i=2,j=3,z=4). In the event that n=4 and a=[1,1,1,1], all four potential triples are suitable. Input The principal line contains a solitary integer t (1≤t≤2⋅105) — the number of experiments. Then, at that point, t experiments follow. The principal line of each experiment contains an integer n (1≤n≤2⋅105) — the length of the succession a. The following line contains n…
Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.

You can make such activity: select 3 distinct cells that have a place with one 2×2 square and change the images in these cells (change 0 to 1 and 1 to 0). Your assignment is to make all images in the table equivalent to 0. You are permitted to make all things considered 3nm activities. You don't have to limit the number of activities. It tends to be demonstrated that it is consistently conceivable. Input The principal line contains a solitary integer t (1≤t≤5000) — the number of experiments.
