I have trouble writing the MSD detector correctly. However, it has no attribute ''create''.
I wrote the following code. But my session crashed for an unknown reason.
msd=cv2.xfeatures2d.MSDDetector()
kps1=msd.detect(I1)
I will appreciate any help.
unfortunately, you've found a bug here.
there should be a ´XXX_create()´ function, but someone forgot to expose it to the python api, by adding a CV_WRAP to the function signature here
(and no, you cannot use the 'ordinary' constructor, it does not produce a valid instance (will segfault, if you call any method on it !!))
please raise an issue here
if you're able to build from src, try to fix it locally, by changing that line to:
CV_WRAP static Ptr<MSDDetector> create(....

Currently i am working on a migration from SlimDX to SharpDX. Some things are different between them, like loading shaders etc:
I have a problem creating the PixelShader class (same applies to the VertexShader class). The problem is, every example I found on this subject will not compile.
For example:
using (var pixelShaderByteCode = ShaderBytecode.CompileFromFile(filename, "PS", "ps_5_0", shaderFlags))
shader.PixelShader = new SharpDX.Direct3D11.PixelShader(device, pixelShaderByteCode);
The problem is, SharpDX.Direct3D11.PixelShader does not take a ComplilationResult as parameter. I could use the vertexShaderByteCode.Bytecode which is a ShaderBytecode, but this is also invalid.
There is a vertexShaderByteCode.Bytecode.Data which is a DataStream. I might create the byte[] from it, but I think this could be solved easier? Did I missed something?
using: SharpDX 3.1.1
I have found the problem:
Looks like i need to reference the SharpDX.D3DCompiler also, to compile for DX11. It was using the DX9 compiler.
SharpDX.D3DCompiler.ShaderBytecode(DX11) vs SharpDX.Direct3D9.ShaderBytecode(DX9)
I'll leave this for anyone who has the same struggles.
CompilationResult is returned by the compile and you can test if the bytecode is null, if it is, you can then check the error codes (Best in debug though :)).
HasErrors : boolean
Message : string
Check these also.
Hello,
My problem is that when i try to import an UDF in Ecxel 2013 I receive the error message can be seen on the picture. I have installed xlwings and it works except the UDF importing. Note that i used "xlwings quickstart myproject" so there is no problem with the file names and i also used the sample function so that should be fine as well
Thank you in advance for your help!
I currently don't understand why you get that error, but I should be able to tell you how you can work around it for now:
Open the file udfs.py in the xlwings package and remove the last argument on line 36, i.e. remove , ArgumentDescriptions=argdocs.
The intended functionality of that line (showing function argument description) is currently broken anyway (see here) so hopefully this will be resolved in a future version.
I download sift implementation from : https://sites.google.com/site/btabibian/projects/3d-reconstruction/code
but i get the error : 'INVERT METHOD' does not exist in the namespace 'Emgu.CV.CvEnum'. from code line : CvInvoke.cvInvert(H, H_inv.Ptr, Emgu.CV.CvEnum.INVERT_METHOD.CV_SVD); any suggestion to solve my problem?
This sample uses a very old version of EmguCV: 2.0.1.0.
The current version is 3.0.
You have to change the CvInvoke.CvInvert() call into CvInvoke.Invert(). The third method parameter is of type Emgu.CV.CvEnum.DecompMethod, so you have to change INVERT_METHOD.CV_SVD into DecompMethod.Svd.
from
CvInvoke.cvInvert(H, H_inv.Ptr, Emgu.CV.CvEnum.INVERT_METHOD.CV_SVD);
to
CvInvoke.cvInvert(H, H_inv.Ptr, Emgu.CV.CvEnum.SOLVE_METHOD.CV_SVD);
change to that work with me
but i still dont know how to add image to the project to use sift algorithm on them
did anyone have arunning project using sift to mack 3d object from many images?
Changing the code line to the following resolved the issue for me on version 2.4.9:
CvInvoke.cvInvert(H, H_inv.Ptr, Emgu.CV.CvEnum.SOLVE_METHOD.CV_SVD);
Hello I'm trying to update some complex fields such as Issue Type or Status using Jira Rest Client Library for Java and I'm having some trouble. This is what I've got so far:
Issue issue = client.getIssueClient().getIssue(issueKey, null);
client.getIssueClient().update(
issue,
ImmutableList.of(new FieldInput(IssueFieldId.ISSUE_TYPE_FIELD,
issue.getIssueType())), null);
As you can see I'm only trying to update the issue type using it's own type (just to test it), however I get an Exception:
Exception in thread "main" com.atlassian.jira.rest.client.RestClientException:
org.codehaus.jettison.json.JSONException: Cannot generate value - unknown type for me:
class com.atlassian.jira.rest.client.domain.BasicIssueType
Am I missing something, is there any documentation for this library that I missed?
I managed to achieve what I was trying to do:
Issue issue = client.getIssueClient().getIssue(issueKey, null);
client.getIssueClient().update(
issue,
ImmutableList.of(new FieldInput(IssueFieldId.ISSUE_TYPE_FIELD,
ComplexIssueInputFieldValue.with("id", id))), null);
This will change the type of the issue, hope this will help anyone else who encounters this problem.
Why I try to run the following OpenCV program, it shows the following error :
ERROR:
test_1.exe - Application Error
The application failed to initialize properly (0x80000003).
Click on OK to terminate the application.
CODE:
#include "cv.h"
#include "highgui.h"
int main()
{
IplImage *img = cvLoadImage("C:\\face.bmp");
cvSetImageROI(img, cvRect(100,100, 100, 100));
cvAddS(img, cvScalar(50), img);
cvResetImageROI(img);
cvShowImage("Test", img);
cvWaitKey(0);
return 0;
}
When i press F5(im using vs2008express), the program encounters a break point...i have attached a picture...dont know, whether, it will help or not.

It is not that, only this program is producing this error, but also any kind of image manipulation funciton containing (OpenCV)program is resulting in this sitution.
Such as : cvSmooth
one last thing, it there any dedicated OpenCV forum or sth like that?
I am an administrator.So, yes, ive the permission.
a version mismatch.
sorry, i didn't get it?Version mismatch with what?
But, i have found the error using dependency walker.
Warning: At least one module has an unresolved import due to a missing export
function in a delay-load dependent module.
and also found that, it is a common problem, and found some info in the FAQ of DW...
Why am I seeing a lot of applications where MPR.DLL shows up in red under
SHLWAPI.DLL because it is missing a function named WNetRestoreConnectionA?
I also get a "Warning: At least one module has an unresolved import due to
a missing export function in a delay-load dependent module" message.
Function name : WNetRestoreConnectionA
But there is no guideline about how to solve it. Though, they say, it is not a problem.
i googled a little and found a suggestion.It says,
Turn off your compilers setting to assume you are programming for Win9x.
(I just lost which setting but it is not that difficult, use a #define...)
But i have no idea, how to do that in Visual Studio 2008 express.
Any suggestion how to solve it...
This usually indicates a problem with a dll; either you don't have permission, or a version is mismatched. Try running as Administrator to see if it is a permissions problem. If that doesn't help, try using the Dependency Walker.
