I tried creating samples for my 100 positive images but run into this error:


At first I assumed that I had not extracted the same number of samples as I was specifying in the command using Objectmarker.exe but even on rectifying that,I still ran into this error.

Currently I am using 100 positive images , but I got the error when I used 70 images as well.

What exactly is the Bad Argument here and how do I fix it?


PS E:\FYP\dasar_haartrain> .\createsamples.exe -info positive/info.txt -vec vector/vector.vec -num 100000 -w 55 -h 35

not really. why does it say: "OpenCV GUI" in the msgbox ? that looks non-standard already

EXACTLY! and the said path does not even exit

"said path does not even exist" -- no, that's the path to the cvxarray.xpp, where the program was built

I think I have finally resolved this issue.

My positive images were named as ' pr(1).bmp, pr(2).bmp, pr(3).bmp' and so on, hence my positive/info.txt file contained these names.

The brackets used in the file names have posed this 'Bad Arguments..' problem .

I changed the file names and I was successfully able to proceed.

This was probable a minor issue which not many must have faced, but I hope this solution helps them when in need :)
