  1. A Cost-Effective Line-BasedLight-Balancing TechniqueUsing Adaptive ProcessingShih-Chang Hsia, Ming-Huei Chen, Member, IEEE, and Yu-Min Chen IEEE TRANSACTIONS ON IMAGE PROCESSING, VOL. 15, NO. 9, SEPTEMBER 2006 指導教授：萬書言 報告學生：賴薏如

  2. Sampling Gain Estimation C：一個section所含的pixe數

  3. Interpolations for Background (text image) SNi：在第N個section裡的第i個pixel值

  4. BC：brightness control

  5. 處理前的pixel level 處理過後的pixel level

  6. Adaptive Gain Processing for Each Pixel
