Patent number: 9841877Abstract: Various embodiments provide a method for determining color information for an image. For example, a color descriptor for an image can be determined and compared against color descriptors stored for each of a number of sample images, which each represent a color in a color space. Upon comparison, matching scores can be generated for a color match between the image and each respective sample image. In this example, the number of sample images with a matching score above a threshold value can be summed and the image can be assigned to a color associated with a highest frequency of the number of sample images. Accordingly, the assigned color of the image can then be used in a “query by color” search or a browse-by-color capability.Type: GrantFiled: February 5, 2016Date of Patent: December 12, 2017Assignee: A9.com, Inc.Inventors: Himanshu Arora, Arnab Sanat Kumar Dhua

Patent number: 9811910Abstract: Approaches are described for managing the processing of image or video data captured by a portable computing device. The device provides a set of images to a remote server executing “in the cloud”. The set of images can include a reference image and at least one other image captured subsequent or prior to the reference.
