Hey with a config

  setGlobalAttribute(0,1);// # 0 -- Profiler::0:OFF 1:ON Default:OFF

        setGlobalAttribute(7,1); //#simple/quality stitch
        // Turn Off/ON ExpoComp
        setGlobalAttribute(1,0);  //# 1 -- ExpoComp::0:OFF 1:ON Default:ON

        // Turn Off/ON SeamFind
        setGlobalAttribute(2,0); //# 2 -- SeamFind::0:OFF 1:ON Default:ON

        // Turn Off/ON Multiband & Num Bands
        setGlobalAttribute(5,0); //# 5 -- Multiband::0:OFF 1:ON Default:ON

        setGlobalAttribute(6,4); //# 6 -- Multiband Bands

i get strange artefacts

@arpu can you send me your loom shell script and test case images.

arpu · 2020-11-17T17:32:13Z

i use c++ qt Gui for this but will try to make a simple loom shell sample

kiritigowda · 2020-11-17T17:36:16Z

@arpu you can look at this sample for reference

arpu · 2020-11-17T17:42:24Z

ok here we go using the sample but with enabled simple stich

(zip includes the output image)

@arpu Running the sample on windows [AMD Ryzen 7 PRO 3700U w/ Radeon Vega Mobile Gfx 2.30 GHz] I had no issue seems to be isolated to Linux. Look at the image below

Also notices that you are using OpenCL 1.2

compared to OK: OpenVX using GPU device#0 (gfx902) [OpenCL 2.0 AMD-APP (3075.12)] [SvmCaps 0 0]

The Loom uses features from 2.0 and that might be a problem. I will investigate, try using OpenCL 2.0

Hey, thx for looking at this

what i think the opencl kernel build should add -cl-std=CL2 ?

clinfo output is

Cool, let me know if using OpenCL 2.0 fixes all these issues. You can send a PR to add an explicit 2.0 flag.

Also, as a side note using features like seamfind and multiband blend makes the image better. See sample below

No SeamFind

With SeamFind

arpu · 2020-11-19T05:06:50Z

ok any idea how i can set the 2.0 flag. ?

kiritigowda · 2020-11-19T05:19:46Z

@arpu try this on your system

sudo apt autoremove ocl-icd-*

Then do a reboot and recompile MIVisionX. Also, check the below command on reboot. Should solve your issue

/opt/rocm/opencl/bin/clinfo

Let me know if this solves the issues.

arpu · 2020-11-19T07:15:22Z

ok from the docs:

OpenCL 2.0 support

ROCm 2.0 introduces full support for kernels written in the OpenCL 2.0 C language on certain devices and systems. Applications can detect this support by calling the “clGetDeviceInfo” query function with “parame_name” argument set to CL_DEVICE_OPENCL_C_VERSION

https://rocmdocs.amd.com/en/latest/Current_Release_Notes/Current-Release-Notes.html

looks like ago do not check this CL_DEVICE_OPENCL_C_VERSION it uses CL_DEVICE_VERSION

kiritigowda · 2020-11-19T07:50:48Z

@arpu I will look into this.

As a temporary workaround, you could boot your machine with windows and try out the flow.

kiritigowda · 2020-11-19T07:53:16Z

@paveltc the stitch mode 1 - simple stitch needs to be added to test. Change sample-1

setGlobalAttribute(7,1);        # 7 -- simple/quality stitch::0:quality stitch 1:simple stitch Default:quality stitch

arpu · 2020-11-19T07:58:38Z

@kiritigowda sorry i have no windows installed

tested with simple stitch and get the Artefacts

kiritigowda · 2020-11-19T08:08:26Z

@arpu will try to resolve this soon, I have a reproducible test case. Thanks for bringing this to our attention.

arpu · 2020-11-25T19:25:29Z

@kiritigowda anything i could provide for help?

arpu · 2020-11-29T03:29:03Z

ok looks like my gpu does not support openCl 2.0
ROCm/ROCm-OpenCL-Runtime#127

anway opencl 1.2 should be good for this

arpu · 2020-12-09T12:13:30Z

@kiritigowda anything i can play with? for what i understand opencl 1.2 should be good for loom

kiritigowda · 2020-12-10T00:52:04Z

@arpu I don't think the OpenCL 1.2 will solve this issue. Some features used in the code require OpenCL 2.0+, let me verify this bug on Linux and see possible fallbacks. I will let you know once there is a resolution. Thanks!

arpu · 2021-01-12T13:37:06Z

@kiritigowda any news on this?

kiritigowda · 2021-03-24T17:58:18Z

@arpu this issue has been fixed with TOT changes, can you verify and we can close this issue?
