| Abstract(in English) | In order to realize adaptive image enhancement, various models based on Retinex theory have been proposed. These models in general did not take into consideration the computational cost. In this report, we propose a technique which reduces the computational cornplexty of retinex without affecting the visual quality of images. As a new method, image layers with low resolution are mainly processed by using the characteristic of spatially smooth. As a result, computational complexity is reduced by 94% for each HD frame. |
