Issues with images, no difference found about image_compare

[nitinramadoss]

Hey there, thank you for bringing this to our attention! The algorithms return zero because transparent pixels are black pixels with 0 alpha. This means that those three images currently equate to images with only black pixels; therefore, the difference is zero.

ChiSquareDistanceHistogram returns a non-zero result because of floating point error.

We are working on a feature to handle transparent pixels and address #3

Hello, do you know when you will add this feature ?

Or do you know another solution to answer to my problematic ?
Initially, I wanted to compare the data bytes of each images but I had an issue with this.

Regards.

You should be able to compare the images for difference if the digits (1, 2 and 3) are in any color other than black.

The package automatically compares the bytes of the images. Each algorithm extracts the bytes first and then compares them with a unique strategy.

Hello, I found a solution to my problem.
I have succeeded to extract the bytes of the pictures, hash them and compare the hashcodes.

My initial goal was to verify if 2 pictures are exactly the same.
Here is my code to get the hash of a picture which is on internet if it can help someone :

final response = await http.get(Uri.parse(pictureUrl));
var bytes = response.bodyBytes;
String imageHashcode = md5.convert(bytes).toString();
