Local Dimming Algorithm of Automotive LCD Instrument Based on Otsu and Maximum Entropy

Backlight Local Dimming Algorithm for High Contrast LCD-TV

A backlight local dimming algorithm is proposed to achieve high static contrast more than 10000:1 on the LCD-TV which is mounted by an LEDarray backlight. On the dark region of the image, the backlight is dimmed to reduce light leakage and get deep dark. The proposed algorithm can avoid or significantly reduce such annoying local dimming artifacts as luminance decrease, nonuniformity and screen...

An Estimation of Distribution Algorithm Based on Maximum Entropy

Estimation of distribution algorithms (EDA) are similar to genetic algorithms except that they replace crossover and mutation with sampling from an estimated probability distribution. We develop a framework for estimation of distribution algorithms based on the principle of maximum entropy and the conservation of schema frequencies. An algorithm of this type gives better performance than a stan...

Image Segmentation Research Based on GA and Improved Otsu Algorithm

In the face of the problem of high complexity of two-dimensional Otsu adaptive threshold algorithm, a new fast and effective Otsu image segmentation algorithm is proposed based on genetic algorithm. This algorithm replaces the segmentation threshold of the traditional two dimensional Otsu method by finding the threshold of two one-dimensional Otsu methods it reduces the computational complexity...

An Adaptive Algorithm of Local Dimming for Liquid Crystal Displays

The local dimming backlight technique enables liquid crystal display to present images with high contrast ratio and low power consumption. Considering that it is more important to make sure a high quality of the displayed image when reducing the power consumption, therefore, in this paper the new algorithm chooses RPSNR (the peak signal-to-noise ratio) =30 as the lowest standard to guarantee th...
