There are no initializations of dim_x and dim_y in:

• https://github.com/KhronosGroup/openvx-samples/blob/master/skin-tone-detector/src/skinToneDetector.cpp#L183
• https://github.com/KhronosGroup/openvx-samples/blob/master/canny-edge-detector/src/canny.cpp#L125

But the standard says (https://registry.khronos.org/OpenVX/specs/1.3.1/html/OpenVX_Specification_1_3_1.html#:~:text=%5Bin%5D%20user_addr,REQ-0928%5D):

In the structure, only dim_x, dim_y, stride_x and stride_y fields must be provided, other fields are ignored by the function [REQ-0927]

This requirement is in all standards.

The OpenVX working group would like to ask the community for feedback and contributions to make OpenVX more accessible to developers. If you have any requests or suggestions on topics to cover or resources to be developed, please ask them here. If you have a resource to suggest please add an issue or pull request here. We look forward to hearing from you!

The OpenVX Working Group

To repository owners: please rename the default branch of this repository from 'master' to 'main', using the Github renaming tool. This request is per policy set by the Khronos Promoters in May 2021, to follow Github community practice for respectful naming.

The Github renaming tool sets up URL redirections and retargets outstanding pull requests, so the impact on repository users is minimal. The most visible issue is that people with local repo clones will probably want to rename their clone's 'master' branch, following the popup instructions that will be seen when browsing the github repository after the change; or just delete 'master' and pull the new 'main', if it's purely a tracker with no local content.

You may wish to coordinate with @outofcontrol if you are doing auto-updates from this repository to another location, whether via push/pull mirroring or other mechanisms. The redirects setup by Github should accommodate most such uses transparently, but it's still good practice.

Based on experience with other KhronosGroup repositories which have undergone this renaming already, this is a reasonable approach:

• Agree on a date for the renaming within the Working Group or other owners of the repository, and document that date here.
  • Date can be adjusted to avoid interaction with major releases in flight.
• Provide notice to repository users outside Khronos, insofar as possible (adding a comment in the repo README with the switchover date is one way).
• Once the renaming is done, edit the new 'main' branch to replace hardwired references to 'master' with (preferably) 'default branch' or 'main'.
• Update the repo README to note the change.

If you have questions or issues about this, please raise them on Khronos internal gitlab 'khronos-general' issue 106 if possible. If not possible, you can @-tag me here.

While we will not force any WG into acting precipitously, this is our agreed policy. Please try to accommodate renaming relatively soon.

Note that this issue is automatically generated, due to the large number of KhronosGroup repositories it's being raised in.

I used OpenCV 3.4.3 to run all applications and show the messages as below.
Can anybody help me? Thanks

While running ./vxPop --donut, getting following error

(VX POP - LIVE:3328): GLib-GObject-CRITICAL **: 15:46:45.249: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

It looks like 'libopenvx.so' is not there. How should I fix this issue?
Moreover, where can I find 'libvx_pop.dylib'?

I get this error when building this.

There is only an implementation of the function vxPublishKernels:
(https://github.com/KhronosGroup/openvx-samples/blob/master/bubble-pop/source/internal_publishKernels.cpp#:~:text=extern%20%22C%22%20%20SHARED_PUBLIC%20vx_status%20VX_API_CALL%20vxPublishKernels(vx_context%20context))

But the standard says
(https://registry.khronos.org/OpenVX/specs/1.3.1/html/OpenVX_Specification_1_3_1.html#:~:text=module)%3B-,The%20module%20must%20be%20a%20dynamic%20library%20with%20by%20convention%2C%20two%20exported%20functions%20named%20vxPublishKernels%20and%20vxUnpublishKernels%20%5BREQ-1923%5D.,-vxPublishKernels):

The module must be a dynamic library with by convention, two exported functions named vxPublishKernels and
vxUnpublishKernels [REQ-1923].

Hi, is ti possible to use openvx with amd e9171 gpu ? If can not, do you know, how can use nnef or onnx file with this gpu ?
