A scene segmentation module detects scene boundaries and segments the video into a number of scenes. For each frame in a given scene, a local white level and a local black level are determined from the distribution of pixel luminance values in the frame. A global white level and global black level are also determined from the distribution of pixel luminance values throughout the scene. Weighted white levels and black levels are determined for each frame as a weighted combination of the local and global levels. The video segmentation server then applies histogram stretching and saturation adjustment to each frame using the weighted white levels and black levels to determine enhanced pixel luminance values. An enhanced video comprising the enhanced pixel luminance values is stored to a video server for serving to clients."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video enhancement for large scale applications","description":"A video enhancement server enhances a video.
