07 Sep 2011TL;DR: In this paper, a method for transmitting additional information together with image data involves replacing pixel values to take in-gamut points to out-of-Gamut points, which may be useful for controlling display and/or processing of the image data; watermark information; or other information.
Abstract: Methods for transmitting additional information together with image data involve replacing pixel values to take in-gamut points to out-of-gamut points. The additional information may constitute metadata describing the image data and/or useful for controlling display and/or processing of the image data; watermark information; or other information. In some embodiments the image data is restored to its original form after extraction of the additional information.

05 Nov 2015TL;DR: In this paper, a region-based quantization parameter (QP) is adjusted in the encoder for a gamma-based or perceptually-quantized (PQ) source electro-optical transfer function (EOTF) source.
Abstract: A high dynamic range input video signal characterized by either a gamma-based or a perceptually-quantized (PQ) source electro-optical transfer function (EOTF) is to be compressed. Given a luminance range for an image-region in the input, for a gamma-coded input signal, a rate-control adaptation method in the encoder adjusts a region-based quantization parameter (QP) so that it increases in highlight regions and decreases in dark regions, otherwise, for a PQ-coded input, the region-based QP increases in the dark areas and decreases in the highlight areas.

15 May 2012TL;DR: In this paper, a media signal is accessed, which has been generated with one or more first processing operations, and a conditional probability score and/or a heuristically based score is computed.
Abstract: A media signal is accessed, which has been generated with one or more first processing operations. The media signal includes one or more sets of artifacts, which respectively result from the one or more processing operations. One or more features are extracted from the accessed media signal. The extracted features each respectively correspond to the one or more artifact sets. Based on the extracted features, a conditional probability score and/or a heuristically based score is computed, which relates to the one or more first processing operations.

16 Jul 2009TL;DR: In this paper, a checkerboard pattern is placed in an image and the image is encoded in a monoscopic video format, which is transmitted to a device where the "checkerboard" is decoded.
Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.

08 Mar 1972TL;DR: In this article, the outputs of two circuit paths, connected to an input terminal, are combined by a variable combining means which responds to a signal level in the circuit to vary the proportions in which the two paths contribute to the output signal.
Abstract: Compressor and expander circuits are constructed by combining the outputs of two circuit paths, both connected to an input terminal. The combining is effected by a variable combining means which responds to a signal level in the circuit to vary the proportions in which the two circuit paths contribute to the output signal.
