In my attachemnet i show with a red rectange a black border point from where i want to start my starting pixel point in every image..plz support
Like I tell many people every month, it's so much easier to do image analysis if your image that you captured is better. This eliminates the step of having to preprocess the image to repair it. So, for you, why are you taking a hand-held photo at some weird angle rather than using something like, say, a flatbed scanner where all your images will start off all aligned? Why not make it easy on yourself, not hard?
Dear image analyst i understand your point of view.. but when we copy 1 lakh copy through straight path scanner there is a chance all images are not straight.. can you help me to detect barcode and read their value from image?
