Add a testcase but I guess it fails

https://github.com/image-js/core/blob/5d3ec49b01cf4243d8841cdc6bd57ee9ecd729aa/src/image/transform/scale/__tests__/scale.js#L52-L61 If factor 3 position should be negative ?

compute properties of ROI

1

Would be nice to have some extra information that can be computed from ROI. Some example of properties are explained in: https://ch.mathworks.com/help/images/ref/regionprops.html

Images of cells are often shifted from one image to another or even worse the cells may divide. It would be nice to have new algorithms to superimpose those images....

There is a file containing a lot of skip testcases https://github.com/image-js/core/blob/master/src/image/transform/mask/__tests__/maskAlgorithms.js This is testing the algorithms for calculations of the threshold of a gray scale image to determine the region...

One library that may be interesting: https://serratus.github.io/quaggaJS/ Likely it should not be put in image-js but we should remember about it ...

Add QRCode decoding

2

Wonder if this library should be added in image-js to read directly QRCode Everybody use more or less the same original source code ... https://www.npmjs.com/package/qrcode-reader http://cirocosta.github.io/qcode-decoder/
