    Abstract: Image details are created for an image. An image is processed to obtain image information. Detected texture samples are processed to obtain texture information. A processor device is used for transforming received image information for obtaining frequency domain information. The texture information is used for determining a lifting factor. A frequency distribution is determined for the frequency domain information using the lifting factor for creating particular frequency. An inverse transformation is performed on an updated frequency distribution for creating output image blocks. The output image blocks are combined to create image details for a lifted image. The lifted image is mixed with the image.

    Abstract: A method, apparatus, and non-transitory computer readable medium for video tone mapping. The method includes a target display receiving a quantized video generated by a master display, the quantized video being mastered for a first range of luminance values associated with the master display; receiving metadata from a tone mapping curve parameter extraction, the metadata comprising at least one maximum value of a luminance parameter of the quantized video as mastered for the first range of luminance values; and de-quantizing the quantized video to produce a de-quantized video. The method also includes at least one processor of the target display applying a tone mapping function defined by a normalized Bezier curve to the de-quantized video; and generating, based on applying the tone mapping function, a tone mapped video mastered for a second range of luminance values associated with the target display.

    Abstract: One embodiment provides a method comprising determining a target color gamut of a display device, an inner zone of the target color gamut, and an outer zone of the target color gamut. The method further comprises dynamically determining, based on the inner zone and the outer zone, a path along which an input color in a source color gamut of an input content moves. The input color is outside the inner zone. The method further comprises mapping the input color from the source color gamut to an output color in the outer zone based on the path. The input color is rendered as the output color during presentation of the input content on the display device.

    Abstract: A method for tone mapping includes configuring, by at least one processor, at least one tone mapping function based on a measure of a distribution of luminance values within video data. The measure of a distribution of luminance values represents a luminance level at which a predetermined percentage of pixels of the video data have luminance values satisfying a threshold condition. The method includes generating a tone mapped video by applying the at least one configured tone mapping function to the video data.
