Hi Thamme, Yes. I am using Ubuntu :) and I had ImageMagick and Tesseract both installed in my system using apt-get. Since, I wasn't sure whether this is a problem with the APT software packages, I built both ImageMagick and Tesseract from sources.
I also double checked the availability of Tesseract and ImageMagick by typing CLI commands that you suggested and the below commands as well, convert test.jpg -resize 64x64 resized_test.jpg tesseract test.jpg out and they worked. I can't find a exact reason why I am not getting metadata but when I used the AutoDetectParser class instead of the TesseractOCRParser class, I can extract both content and metadata. p.s. I will put updating the wiki OCR page in my TODO list :)
