    摘要: Devices, methods, and non-transitory program storage devices are disclosed to provide for the application of color treatments and/or color normalization operations to digital assets (DAs) in a set of DAs that are to be displayed as part of a multimedia presentation. The determination of the color treatment may be based on comparing one or more characteristics of an audio media item associated with the set of DAs to a corresponding one or more characteristics of a plurality of predetermined color treatments. Color normalization may be applied to the set of DAs prior to the determined color treatment. Techniques disclosed herein may also determine one or more parameters for a multimedia presentation of the set of DAs based on a characteristic of the associated audio media item. The parameters for the multimedia presentation may comprise one or more of: preferred DA sequences, portions, clusters, layouts, themes, transition types, or transition durations.

    摘要: A method of image processing is disclosed herein, the method comprising: obtaining a first image comprising a first plurality of pixels; obtaining a first segmentation map for the first image, wherein the first segmentation map comprises a first plurality of segmentation values; performing a histogram analysis on the first plurality of pixels, wherein the histogram analysis is weighted based on each pixel's corresponding segmentation value in the first segmentation map, and wherein the histogram analysis comprises determining at least: (a) a median luminance value for pixels that are estimated (e.g., based on their segmentation values) to be part of the background of the first image; and (b) one or more dominant hues for pixels estimated to be part of the background of the first image; and suggesting a first image treatment for the first image based on the determined median luminance value and/or the determined one or more dominant hues.
