Abstract: Systems and methods are provided for capturing time-stamped data from whiteboard video signals and producing high-resolution whiteboard images. Local patches around a multitude of pixels in the whiteboard are used in classifying background white pixels and foreground color pixels for each foreground marker color. Clustering is performed in alternative color spaces globally and locally in defining background white and each foreground marker color. Color normalization is performed for each foreground pixel classified as a foreground marker color and for each image sensor color plane separately utilizing the maximum local background white and the darkest pixel intensities in local patches. Strokes are reconstructed based on spline interpolation of inflection points of cross sections along the length of each stroke for a foreground marker color with a predetermined width.

Abstract: Systems and methods are provided for compensating bias introduced from various image signal processors (ISP) or ISP components while effectively reducing noise. An ISP stage such as spatial noise filtering, high dynamic range (HDR) interpolation, and demosaicking among others, often results in various types of biases and artifacts being introduced in the output frame. The methods and systems of this disclosure employ a convex combination of multiple input frames or blocks of pixels, to effectively reduce bias from a spatial noise filter, a debayer unit, or other ISP components, thereby providing improved spatiotemporal noise reduction solutions.

Abstract: Systems and methods are provided for alleviating bandwidth limitations of video transmission and enhancing the quality of videos at a receiver. In particular, an improved video transmission system is provided for generating high-resolution videos. The systems have therein a transmitter and a receiver; the transmitter includes an outer encoder and a core encoder, while the receiver includes a core decoder and an outer decoder. The outer encoder is adapted to receive the video from a source and separately output a salient video and an encoded background, and the outer decoder is adapted to merge the background with the salient video thereby producing an enhanced video. Also provided is a system that simulates pan-tilt-zoom (PTZ) operations without PTZ hardware. Further provided are methods for video transmission whereby a background model is initialized, a background independently encoded, updated incrementally, and the background and the updates transmitted independently from the video.

Abstract: Systems and methods are provided for alleviating bandwidth limitations of video transmission, enhancing the quality of videos at a receiver, and improving the VR/AR experience. In particular, an improved video transmission and rendering system is provided for generating high-resolution videos. The systems have therein a transmitter and a VR/AR receiver; the transmitter includes an outer encoder and a core encoder, while the receiver includes a core decoder and an outer decoder. The outer encoder is adapted to receive the video from a source and separately output a salient video and an encoded three-dimensional background, and the outer decoder is adapted to merge the background with the salient video thereby producing an augmented video. Also provided is a system that simulates pan-tilt-zoom (PTZ) operations without PTZ hardware.
