Re: SOCLES

[Michael Zucchi]

Hi Lorenzo,

In the code i'm looking at (hessionDet_kernel.cl), responses and
laplacians are both write_only image2d_t types (line 49, 55). It might
have something to do with the opencl support level of that graphics
card/driver - check the nvidia documentation.

socles doesn't use OpenCV or CUDA. You should also use the mailing list
for socles questions.

Regards,
Michael

I tried to find some solution without success, anyone have some idea? I can´t really understand why it reads __read_only when the image type is __write_only..

Hi Again,

About all I can suggest is trying a different opencl implementation,
e.g. the amd or intel cpu driver. Obviously it wont give gpu
performance, but it might rule out the code itself as the issue.

Hi, thank you again!
I tried with CPU. On my notebook with intel core2 everything run just
fine and i had this output:

But when i tried with another pc with intel core i5 i had a problem
with this output:

So i tried to change the image type to R_Type to RGBA_type and in this
way i did not have this error anymore but i have a new error:

any idea? Thank you again

Hi,

The code uses all sorts of image types, so without proper image support
it could be a hassle to convert it. Have you tried the AMD cpu driver?
It works fine on intel cpu's and supports images properly.

But that looks like it could be a bug with the image loader, what types
are the input buffered image and the target CLImage2d?

Michael

[Lorenzo]

Hi,
now with AMD driver everything run just fine with my CPU! Thank you very much!
The target CLImage2d i was using in the putImage method was RGBA_UINT8
and the buffered image was the file read from a jpeg color image.
Thank you again!

[Lorenzo]

Hi, 

i have another problem.. I´m using your library to try to find matching images. I choose an image and i try to run a ransac for each image in another folder trying to find the one with best inlier distribution to find matching images. The problem is that after trying matching various images I get a com.jogamp.opencl.CLException$CLOutOfResourcesException: can not enqueue 2DRange CLKernel.

I tried in many ways to deallocate the resources after each matching without success. Do you have any idea of how can i free resource in order to be able to run the algorithm multiple times? Thank you very much!

Lorenzo

[Michael Zucchi]

Hi again,

Hmm, dunno, could just be a bug in the code. I haven't tested it much,
let alone on a cpu. Although I have run a version of it on live video
for at least a few minutes without troubles.

Do you have your stuff available somewhere online?

Michael

[Lorenzo]

Hi, 

I edit your RANSACFeatures code to run multiple time on the same images and in this way i get the same error running many times the same thread on the same images 9MPixels images of 4MB in jpeg.

My video card is an AMD 6770. After 10 times i get the same exception i wrote you about. 

Please find attached the modified code.

Thank you

Lorenzo

[Michael Zucchi]

JOCL doesn't do garbage collection, resources must be de-allocated
manually, that loop is guaranteed to fail.

When I processed video i pre-allocated all the buffers and just re-used
them.

[Lorenzo]

Thankyou I´ll try in this way! Do you know how manually deallocate resources in jocl? Thank you very much!
