发明名称 System and methods for determining color characteristics of an image
摘要 Disclosed embodiments relate to a method implementable on a computing device for determining color characteristics of an image. The method includes identifying one or more regions in the image based on a luminance value associated with pixels in the image. Each region comprises a set of pixels having a predefined range of luminance values. The set of pixels associated with the one or more regions are categorized into one or more predefined color categories corresponding to each of the one or more regions, based on a chroma value associated with each pixel in the set of pixels. The color characteristics of the image are determined based on a count of the categorized pixels in each of the one or more predefined color categories.

主权项 1. A method implementable on a computing device for determining color characteristics of an image, the method comprising: identifying one or more regions in the image based on a luminance value associated with pixels in the image, wherein each region comprises a set of pixels having a predefined range of luminance values; categorizing a pixel in the set of pixels in one or more predefined color categories based on a chroma value associated with the pixel, wherein the one or more predefined color categories are determined based on luminance values associated with the set of pixels in a region, from the one or more regions, associated with the pixel; determining a weighted sum of count of pixels, categorized in each of the one or more predefined color categories, for each of the one or more regions; and determining the color characteristics of the image based on a number of regions, from the one or more regions, having the weighted sum exceeding a predetermined threshold.
