Array([1] 34[2] 1[4] 67)true You have to know the order you place the arrays in thearray_diff()functions impacts that return an array. With the same code, if we change the order of the arrays, the output below is the result. ...
Thearr1andarr2are the arrays to be compared. Thesizeis the size of the arrays. Let’s explore a complete working example of comparing arrays using a custom-defined function: #include<iostream>#include<vector>using namespace std;template<typename T>boolcompareArrays(constT arr1[],constT arr...

2. Pixel comparison Another function that could also work if we're comparing pixels could be just simply identifying pixels that are the same or different across screenshots of the same size. I'd like to take two screenshots, and get an output like that third image there, simply a two-col...
Convert PyTorch tensors to numpy arrays img1_np = _img1.numpy() img2_np = _img2.numpy() Compute SSIM score with win_size=3 ssim_score = ssim(img1_np, img2_np, multichannel=True, win_size=3) print("True vs False Image SSIM Score: ", np.round(ssim_score*100,2) ,"%") ...
JSON.stringify()to Compare Arrays in JavaScript Another technique to compare two arrays is to first cast them to the string type and then compare them.JSONis used to transfer data from/to a web server, but we can use its method here. We can do this is usingJSON.stringify()that convert...
