New method to assess enhanced image quality based on luminance

This paper proposed a new method to assess enhanced image quality based on luminance, studied the relationship between image luminance and image quality and the experiments proved the trend of image quality and image luminance under different visual conditions. Firstly, the image quality method to assess the enhanced image was established, then in order to get accurate results, we adopted two different luminance adjustment methods to study the relationship of the luminance and image quality assessment. Finally, the relationship between the image quality and the luminance was experimentally verified. Results shows that the image quality method can directly apply to assess the image quality and the relationship of the image quality and the luminance is a convex and non-linear function. According to the new method proposed in this study, we can use the relationship of the image quality and the luminance to adjust the luminance and achieve the best visual image quality and the research result will lay the foundation of image quality assessment.
