2018-01-15 07:32:00 -0600 | marked best answer | Nvdia Cuda gpu implementation and filters with opencv I just would like to inform you that according to performance criteria i would like to transfer image processing algorithms from CPU to GPU.Therefore I will be able to run it faster in high resolution image(I hope) But unfortunately ı get some errors using filters in But unfortunately there is an error indicating after using apply function for filters(I found in Debug) : The error is :
I would like to share function that includes the sobel filter operation for clear understanding. Code : cuda::GpuMat Morphology::Sobel_operations(cuda::GpuMat& gray_image) } |

2017-12-11 06:14:20 -0600 | marked best answer | Image rotation problem in for loop(Geometric transformation) Nowaday I am trying to write barcode reader program with opencv and zbar.The code works correctly, but the zbar plugin only reads the bar code on the horizontal and vertical axes.For this reason, I want to rotate the cross image at the end of the image output.So zbar will read the picture correctly. But unfortunately I could not rotate the image correctly in the for loop. It rotates the image but does not do this for 180 degrees.I tried to write the code correctly, but I could not reach the end result.I think there's a problem with the warpaffine geometric tarnsformation function. Any help will be apreciated to find the solution. Here is example image outputs which is not properly rotated according to specified angle in for loop with explaination : For loop(main code part) , which will be able to rotate image untill 120 degree of angle : Here is the rotation function which is called above by zbar_scanner.Image_Transform=Geometric_Transformation(zbar_scanner.cut_image_zbar1,tr); } |

2017-12-11 06:13:58 -0600 | marked best answer | Barcode recognition, Sobel derivatives and image transformation problem! First of all, I am developing a program for barcode reading.I use Sobel derivatives to obtain Gradient representation of image in x and y direction for barcode bars.It works very well in both directions(0 to 270 degree). But unfortunately Sobel derivative representation can not recognize another angle of the image.I don't know how to explain it, but you can understand it by looking at the two different pictures I've added below. Correctly recognized barcode bars, Can not detect from the same angle in reverse view, Here is my code for sobel derivatives , I have added y direction gradient view to x direction using addweighted command. It is really strange.Any help will be apreciated to solve this problem. |
