hi all experts, im daniel from malaysia.
i am doing this project, title "EAN barcode reading by using Camera phone"
i am supposed to take a picture by using phone camera, then doing pre processing and decoding with algorithm.
i am now facing difficulties in sharpening the image. i take pictures of barcode with a HTC phone, 5 megapixel, but when i am trying to make sure the picture is in the grid, the picture will lack of focus, i tried using different sharpening ways but it ended bad. hopefully experts in here can share with me your knowledge.
your replies are greatly appreciated.
