 |
|
Is it possible to check if a given image is inside a bigger image in
an easy way, using OpenCV? The main purpose is to recognize objects
inside a picture, e.g: I have the image of numbers and I check in a
picture (for example, a car license plate) if these numbers (or its
original images) are inside the bigger image. This is for a college
workpaper and doesn>t have to be so accurate. I would appreciate an
answer citating the library/method avaiable to do it.
Thank you!!! |

check cvMatchTemplate (or something similar), however this will only
work if the template matches very well the object on the test image.
Object recognition is a hot topic, what people mainly use are invariant
features, like SURF or SIFT. |
