28‐2: A Novel Local Dimming algorithm with HDR for VR system based on GPU
SID Symposium Digest of Technical Papers, 2019As the screen of VR is very close to human eye and the optical lens has amplification effect, VR needs high PPI to meet people's visual requirements. High PPI panel with side‐emitting LED backlight is difficult to realize high contrast ratio(CR). Local Dimming based on direct‐illumination LED can not only save backlight power consumption but also ...

In order to realize accurate detection for small dim infrared maritime target, this paper proposes a target detection algorithm based on local peak detection and pipeline-filtering. This method firstly extracts some suspected targets through local peak detection and removes most of non-target peaks with self-adaptive threshold process.

Abstract This paper proposes a global backlight dimming algorithm based on structural similarity that controls the local distortion level of the output image for preserving overall image quality. Unlike existing methods, the proposed method non-iteratively determines a global clipping point that maintains structural similarity for each pixel above ...

Abstract: SSC local dimming algorithm is an effective method to control the LED backlight for maximum power saving of LCDs. In a former paper we proposed add‐ons to the SSC frame named Correlator and Combiner which enhance the static contrast ratio or achieve further power saving depending on different Combiner ...

P‐56: New Brightness Uniformity Tuning Algorithm for LCD Panel with Local Dimming Function
SID Symposium Digest of Technical PapersLCD panels with 2D LED backlights often face brightness uniformity issues. This paper introduces an algorithm leveraging LED diffusion characteristics to address this. By projecting patterns and capturing luminance distributions, the algorithm corrects local brightness variations, compensating for mura effects and LED inconsistencies.
