Based on https://www.chromestatus.com/feature/4757990523535360 is just released on Chrome 57 stable "Behind a flag". Where can I find it in  chrome://flags? It seems not having it.

#11: either "the flag" that enables all interesting stuff:
chrome://flags/#enable-experimental-web-platform-features

or the individual 
--enable-blink-features=ShapeDetection

#12: then https://www.chromestatus.com/feature/4757990523535360 status is wrong. None of https://codepen.io/collection/DwWVJj/ tests works even on Chrome Canary 59.0.3038.0 chrome://flags/#enable-experimental-web-platform-features enables.

#13: I just tried some on Mac 59.0.3037.0 and most of
them work; plz make sure that you access via https:// 
Also, the code is wired on Mac and Android only ATM, plus:
- Mac QR detection doesn't detect slanted QR codes, not
 barcodes;
- Mac Text detection detects "bubbles" of text, but 
 doesn't decode the text inside.

@mcasas, tested over HTTPS on Win10 64-bit build, all test-cases fails with warnings like "Boo, Text Detection failed: NotSupportedError: Text Detection not implemented.", https://codepen.io/collection/DwWVJj/

#15: only the Mac and Android implementations are wired 
so far. Win10 will be coming soon.

#16: @mcasas, I suggest you update the status in https://www.chromestatus.com/feature/4757990523535360, currently shown "Chrome for desktop release 57" what's understood as supported on Windows desktop.

TAG review https://github.com/w3ctag/design-reviews/issues/176

FYI we are aiming to land Shape Detection as an Origin Trial in Chrome 61

This is great. Just tried the API and it works like charm.

This issue has been automatically relabelled type=task because type=launch-owp issues are now officially deprecated. The deprecation is because they were creating confusion about how to get launch approvals, which should be instead done via type=launch issues.

We recommend this issue be used for implementation tracking (for public visibility), but if you already have an issue for that, you may mark this as duplicate.

For more details see here: https://docs.google.com/document/d/1JA6RohjtZQc26bTrGoIE_bSXGXUDQz8vc6G0n_sZJ2o/edit

For any questions, please contact owencm, sshruthi, larforge

Is there a target version for this functionality to be available not behind a flag? It would be great to get an idea of when end user's can use this so we can plan our integration. Thanks.

Do we have a target version for this functionality? We would like to start integrating it into our application but it would be helpful to first understand if/when this will be available to all users without a flag. Thanks.

+reillyg@ since he mentioned something about an Origin Trial some time soon.

I will take ownership of launching an Origin Trial for this API soon.

Great news! :)

I cannot find a enable-experimental-web-platform-features flag in Chrome 68 for iOS.I wanna detect barcode in PWA.How can I do it?

funaox@, there is no such flag in Chrome for iOS because it does not use the Blink rendering engine and we therefore cannot add web platform features beyond those supported by Mobile Safari.

Add use counter for the Shape Detection API

This use counter measures calls to the detect() methods provided by the
BarcodeDetector, FaceDetector and TextDetector classes. This is needed
by the Origin Trial infrastructure so that we can measure use of this
API in general rather than use of each detector type individually (which
is covered by the existing use counters).

ShapeDetection: Remove Shape Detection Register in utility

Shape Detection runs on gpu process, so the Register in utility isn't necessary.

Will windows 7 get this API capability? I've done a lot of google search, but I couldn't find the answer.

zjlovezj@: Win10 should support Face and Text detection [1] and
IIRC they should be implemented [2,3]
