gheinrich / bibnumber Goto Github PK

i try build it on ubuntu but it is not ok.
../batch.cpp:12:10: fatal error: opencv2/objdetect/objdetect.hpp: No such file or directory

I'm just found your repo and it's amazing, I wanna to tryout but can't figure out how, I'd downloaded all dependencies but do you have a step by step windows install procedure?.

I'm using VS2017, Windows 7 32bit

...the loose files in the bibnumber executable directory, I just want to create the .csv files as output, is it possible?

Thank you!

I cant seem to replicate the output for the README sample. When i process it, it returns a blank list.
When using the svm-prom model provided, it only captures [46, 54].
Is it necessary to train a svm model from scratch? Am i doing anything wrong?
Im running the example as follows:

../bibnumber/Debug/bibnumber -model ../svm-prom1.xml 0017-IMG_0035.JPG

hi

first, thanks for this project :)

i just builded it on ubuntu 15.10 but when i try a simple

./bibnumber /my/path/*

i have

ERROR: Could not load classifier cascade

could you add some exemple to get the results you have in the demo ?

2/ with this batch is it possible to get the original image name of the detected bib ?

thanks !

any idea?

When having a load of pictures from a local event, it would be awesome to point the code to a certain directory containing all the pictures, detect bib-numbers on each of the pictures (one picture might contain several), and then copy the pictures into folders representing each bib.

Example:
Folder \eventX contains:
pic1.jpg - with competitor 145
pic2.jpg - with competitor 153
pic3.jpg - with competitor 167 AND 153
pic4.jpg - none recognizable bibs.

Run the program - it will copy into folders for each numbers;
\eventX\145\ will contain pic1.jpg
\eventX\153\ will contain pic2.jpg AND pic3.jpg
\eventX\167\ will contain pic3.jpg
\eventX\NOT_FOUND\ will contain pic4.jpg

(note - pictures are copied into the folders - and pictures 3 ends up in two folders as it has two different bibs).

Have you or anyone you are aware of used this on a web server? My use case would be to install it on a server and give PHP the ability to execute against a directory. I could then script the pulling of CSV data into a database associating bibs with other athlete info.

Is this even possible? Any pointers in the right direction would be appreciated.

Thanks!

Dears,

is possible to ask you for a help with the installation? Tried everything, but can not run the app.

Thank you for your help.

Hii , Nice work , which paper did you consult for implementing the algorithm for text detection ?

Hi @gheinrich,

first of all, many thanks for this project :)!

Can you send me the commands you used in order to generate the file "svm-prom1.xml" and specify the set of pictures you used to do it? Can you help me @gheinrich ?

I tried several times to create it with the pictures you provide in the project, but I get this error: OpenCV Error: Assertion failed (0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows) in Mat, file /home/nurgle/Scrivania/opencv-2.4.9/modules/core/src/matrix.cpp, line 323
terminate called after throwing an instance of 'cv::Exception'
what(): /home/nurgle/Scrivania/opencv-2.4.9/modules/core/src/matrix.cpp:323: error: (-215) 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in function Mat.

I use this command: "../../bibnumber/Debug/bibnumber -train . ." in a folder with the "prom*.jpg" pictures, since I believed you used the "prom*.jpg" pictures to create the aforementioned "*.xml".

Many thanks in advance for your attention.

Best regards,
@Nurgle87

I get the following error message:

tesseract/baseapi.h: No such file or directory
#include <tesseract/baseapi.h>

I could not find this file in any of the downloaded directories.

Hi @gheinrich, first of all, great project!

I'd like to know if this project can be compiled statically, do you have some tip to create portable binaries?

Thanks!

I was able to build bibnumber on the following setup

• Windows 10
• Visual Studio 2017 15.9
• CMake 3.13
• latest leptonica, tesseract from GitHub + CPPAN
• OpenCV 2.4
• Boost

With a bit of coaxing I was able to get it to compile. However when running the program

bibnumber <path_to_images>

The processing stops as the first image. I was able to trace it to textdetection.cpp findLegallyConnectedComponents, right on the last statement return components.

For some reason it takes forever to exit this method.

This happens on the Debug build.

When compiled for Release, the program progresses further, generating bib-components, bib-rotated and bib-tess-input images, however, it crashes with a heap corruption error.

During make -C bibnumber/Debug I got the following errors.

../textdetection.cpp:230:3: error: 'rectangle' is not a member of 'cv'
   cv::rectangle(tmp_mat, it->first, it->second, c);
   ^~
../textdetection.cpp:231:3: error: 'putText' is not a member of 'cv'
   cv::putText(tmp_mat, txt, it->first, cv::FONT_HERSHEY_SIMPLEX, 0.3, c);
   ^~

I am using opencv-dev@testing despite testing state it should theoretically not having namespace errors like this.

Should I specify the cv namespace somewhere in compile time?

Good morning,

I'm interested in the program, contact me at the mail [email protected]
