I I am new to opencv. I will need some help. I want to detect titleblock in technical drawings through opencv. There will be a sample title block and there will be set of drawing files in which I have to detect the location of title block. The drawings can have (90n +/- 5) degree of rotation. The drawings will have contain title block of different dimensions. I have tried surf,freak, template matching. But all of these are not giving perfect results. I also would like to know in which cases object should be detected via surf like feature detection and in which cases LBP, Haar like cascade training? Sample drawing file from internet Sample Title block title.png
The approved by, date, title are filled with different values in different drawings but the overall structure and some of the text is same in title block.
Any suggestions would be of great help!! Thanks
