| We developed an image enhacement technique for dichromats (color blinds). We formulated the differetial values of neighboring pixels as Poisson equation, and solved it using sparse matrix library. We transformed the color so that the color difference of neighboring pixels which trichromats (normal vision) recognize and the color difference of neighboring pixels which dichromats recognize become the same. |
