Histogram methods and systems for object recognition

摘要: A multidimensional histogram is used to characterize an image (or object), and identify candidate matches with one or more reference images objects). An exemplary implementation employs hue information for two of the dimensions, a second derivative function based on luminance third dimension. The simplicity speed detailed arrangements make them well suited use cell phones other mobile devices, which can technology image/object recognition, e.g., in visual search applications.
