Abstract

In this work an analysis of the influence of contrast modification on people´s opinion is performed. Based on a previous study of the impact of image contrast modifications on human feelings, here we address the problem of determining the impact of the image contrast change on the opinion of a person. This analysis is based on subjective tests that have been performed exploiting crowdsourcing. The obtained results show a good correlation with the previous work and they witness the possibility to influence subjective opinion by means of contrast modification. This study can results in forensics tools for blind detection of opinion biasing by means of image processing.
