How to normalize an image to a range of values

Question

In a publication, I read that an image should be normalized from [0 to M]. I searched google for a normalization method and I get this link , which is the closest to my needs. But still I do not know how to normalize an image to a range of values?

Please let me know how to normalize an image to a range of values and is there any opencv method that does that normalization operation?

Update :

concerning the norm_type, i found a comparisons between L1 and L2 here .should i just pick any one of them or there is a specific norm_Type suitable for image normalization

Answer 1

What you want is cv::normalize . Also, its Java equivalent can be found here .
