Shortest way:
float alpha, beta = ...
Mat image = imread( argv[1] );
2 | No.2 Revision |
Shortest way:way via matrix expressions:
float alpha, beta = ...
Mat image = imread( argv[1] );
3 | No.3 Revision |
Shortest way A quick and dirty contrast enhancement via matrix expressions:expressions and a linear transformation:
float alpha, beta = ...
Mat image = imread( argv[1] );
image += beta;
image *= alpha;
For instance, set beta to -(minimum value)
and alpha to (maximum value - minimum value)
