دراسة تاثير اتجاه توزيع الاضاءة على تحسين الصور مختلفة الاضاءة بتقنية معادلة المخطط التكراري

We went in this research is to study the effect of the distribution of lighting on the quality of still images under different conditions there by improving the resulting image of the imaging system using a technique adaptive histogram equalization depending on the space YIQ by depending on Component of lighting only where the use of reverse conversion of this space to the basic space RGB colors and then corrected using the theory based on human vision system. Results were analyzed and measuring of quality improvement by using various statistical criteria based on the expense of Mean, standard deviation and contrast.
