Error when running table recognition evaluation

[zhxgj]

Hi, I used the following command to use the jar to evaluate my table recognitions. java -jar dataset-tools-20180206.jar -reg eu-001

But I got the error message below: Using GTFile: eu-001-reg.xml Using resultFile: eu-001-reg-result.xml Using PDFFile: eu-001.pdf startPage: 1 endPage: 2147483647 Current page no: 1 Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/jai/PlanarImage at at.ac.tuwien.dbai.pdfwrap.model.document.GenericSegment.tagName(GenericSegment.java:425) at at.ac.tuwien.dbai.pdfwrap.model.document.GenericSegment.toString(GenericSegment.java:215) at java.base/java.lang.String.valueOf(String.java:2801) at java.base/java.lang.StringBuilder.append(StringBuilder.java:135) at at.ac.tuwien.dbai.pdfwrap.pdfread.PDFObjectExtractor.processPages(PDFObjectExtractor.java:1464) at at.ac.tuwien.dbai.pdfwrap.pdfread.PDFObjectExtractor.findObjects(PDFObjectExtractor.java:1413) at at.ac.tuwien.dbai.pdfwrap.ProcessFile.processPDF(ProcessFile.java:188) at at.ac.tuwien.dbai.pdfwrap.MeasureRecognitionPerformance.main(MeasureRecognitionPerformance.java:291) Caused by: java.lang.ClassNotFoundException: javax.media.jai.PlanarImage at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496) ... 8 more

My result file is attached below. eu-001-reg-result.xml.zip

@GZDXLQH I did not attempt to solve it because I am not familiar with java...

@zhxgj OK, thanks for your replay.

Hi, there seems to be some problem with dependencies. Sorry about this. I will do a new build next week and update the libraries to the newest ones. In the meantime, you need to add com.springsource.javax.media.jai.core-1.1.3.jar, pdfbox-app-1.8.1.jar (not pdfbox-1.8.1.jar) and commons-collections-3.1.jar to the classpath and it should work.

I have now pushed these extra JARs to the /lib directory. I will look at the code next week and see if I can remove these dependencies, but this should get you up and running for the time being.

Hi @tamirhassan @GZDXLQH , I got the same problem. How can I fix it? I have added com.springsource.javax.media.jai.core-1.1.3.jar, pdfbox-app-1.8.1.jar (not pdfbox-1.8.1.jar) and commons-collections-3.1.jar to the .classpath file and running with the following command java -jar -classpath .classpath dataset-tools-20180206.jar -reg ../icdar2013-competition-dataset-with-gt/competition-dataset-eu/eu-001 I get the following error: Error: Could not find or load main class dataset-tools-20180206.jar

@chuong-phung Hi， I am sorry to tell you I can't help you. I am not good at Java. So far, I don’t have time to re-evaluate the experiment according to tamirhassan's solution. (In fact, before tamirhassan gives me the solution, I have used the ICDAR 2019cTDaR tools to evaluate my recognition result of my table).
