I am new to open source and would like to contribute to scikit image. I couldn't find scikit methods to evaluate contrast measures. Image quality metrics like EME, EMEE, AME etc are helpful in writing contrast enhancement algorithms. I would like to know if it is something scikit-image interested in and if so how should I proceed? 

Specifically I am talking about Table 1 of https://doi.org/10.1109/TCE.2013.6626251. It summarises commonly used gray scale measures.
