Design And Implementation Of Color Vision Auxiliary Tools

Color blind people can't normal color in visual information,the serious influence their daily life and even their study and work.Based on the IOS system designed and developed a color auxiliary software,can make the color blindness patients by mobile phone use this software to complete color blindness correction color blindness.The work of this paper are arranged as following:First,this paper deeply studies the correction of color blind algorithm at home and abroad research situation,starting from the present situation,the color blindness correction algorithm developed into a software applied to mobile phones,convenient for patients also makes the color blindness correction algorithm is applied more widely.This is also the purpose and meaning of this paper.Then,in this paper,on the basis of the principle of color blindness have deep insight into two color blindness and color blindness model respectively for the modeling and simulation results are given,analyses the expression in patients with eye image;Then the paper studied the color blindness correction algorithm and the blind correction algorithm of H component rotation,and analyzed the two algorithms.The experimental results show that the image will exceed the range and be shown in black,which will cause the pure color to be not clear at all.The color of the simulation does not match the color of the color blind,which can lead to misunderstanding or misunderstanding.And light and shade of color blindness correction algorithm is put forward,through the experiment,the rectified image was implemented and color blindness see images is consistent,even if the data out of range,also won't appear black,makes image information becomes more bright,the surrounding information becomes very dark,with light and shade to distinguish the image information.Light and shade correction algorithm can make two color blindness patients will be two of the most confusing color with light and shade,allowing patients to effectively capture the image information,so as to correct the purpose,and verify its superiority.Finally,the color blind image correction system based on IOS was developed and the color blindness correction application was developed based on the light and dark color blind correction algorithm.Through the test,the system can not only simulate the real image of red color blindness,green two-color blindnessand blue dichromatic blindness in the eyes of color blindness,but also distinguish the colors that are indistinguishable from color blindness.The test of the system shows that the system can help color-blind patients to identify the color blind detection graph in terms of color blindness correction.And for the transformed images,color blindness and normal people have the same visual experience.In color blind simulation,the system can reproduce color-blind visual images more vividly,and can be applied to color blind testing and experience.The experiment proves that the color blind auxiliary software designed in this paper can achieve better correction of color blindness,and it has the characteristics of convenient operation and stable results.It can be seen that the color blind correction software designed in this paper can achieve the aim of correcting color blindness and improving users' comfort.
