DETECTING OBJECTS IN IMAGES USING COLOR HISTOGRAMS

摘要

Methods, apparatus and articles of manufacture for detecting objects in images using color histograms are disclosed. Example methods disclosed herein include determining differences between bin values of a first color histogram corresponding to an object and respective adjusted bin values of a second color histogram corresponding to a first subregion of an image. Such disclosed example methods also include determining a first metric based on the differences. Such disclosed example methods further include comparing the first metric to a threshold to determine whether the first subregion of the image corresponds to a first possible location of the object in the image.

1. A method to detect an object in an image, the method comprising:
determining, with a processor, differences between bin values of a first color histogram corresponding to the object and respective adjusted bin values of a second color histogram corresponding to a first subregion of the image; determining, with the processor, a first metric based on the differences; and comparing, with the processor, the first metric to a threshold to determine whether the first subregion of the image corresponds to a first possible location of the object in the image.
