i got two images.. offline mode -> http://postimg.org/image/jbqk07wyr/ online mode-> http://postimg.org/image/i3yul17xt/ i want to match the image that i get from live scan with the inked images i got in my database. It will be very helpful if you guide me to the direction i should head, thanks

Hello there, I have got two fingerprint images of a same person. One is inked image and the other image is through digital persona finger print scanner. Is it possible to match and recognize these two fingerprint images ?

Hello everyone,

Suppose i got an image of a hand written form on which a fingerprint is imprinted. It can be anywhere on the form. How a program can detect the fingerprint and extract that region on interest ?

i can extract the ROI, but i am not sure how to detect that region.. Please guide me how can this b achieved..

Thanks

you can resize your image by using this code,

double ra=1.0; int newWidth; int newHeight; int main() { Mat size= imread("your filename"; double ff=700; // this will change the image resolution to 700X700 if (size.cols > size.rows) { ra = ff / size.cols; } else { ra = ff / size.rows; } newWidth = (int)(size.cols * ra); newHeight = (int)(size.rows * ra); cv::resize(size,size,cv::Size(newWidth,newHeight)); imshow(size);
}

Thanks alot my friend... really appreciate your support:)

Hello all, I am using grabcut sample code from opencv as a part of my project... the final image which i am getting after using that sample code contain black background... according to me, it is because of the mask....?? i have tried everything to change the background to white or transparent...

what modification should i make to the sample code to get final image with white or transparent background...

thanks,

do u know any sample code to perform this ?

thanks i m trying to do so.... actually this is the first time i am using opencv ever in my life... so still in learning process... and my deadline to do the whole project is after 2 days.... and this edge refining/ smoothing is the last part where i m stuck

but this will convert my image to grayscale.... i need it to b in RGB

hello all,

is there any way to smooth or refine irregular edges in an image...for example the edges in the image below : C:\fakepath\wiqi.jpg

Thanks,

Thanks for the reply....i have updated my question...

Hello all, i am working on a project, for which i am using grabcut sample code. it is working perfectly... But my question is, how can i save the final image after the required iterations... so that i can use that image for my further processing.... Waiting for replies...

Thanks

update: C:\fakepath\result.jpg after saving the final result...rectangle is still visible...how to get rid of that ??
