An example method includes generating a first fluctuation factor for a first frame by averaging fluctuation values of a random set of pixels of the first frame; generating a second fluctuation factor for a person indication area of the first frame by averaging fluctuation values of pixels of the person indication area; and marking the person indication area as a false positive when the second fluctuation factor is less than or equal to the first fluctuation factor. | 10-03-2013 |
20130259381 | METHODS AND APPARATUS TO COUNT PEOPLE IN IMAGES - Methods and apparatus to count people in images are disclosed. An example method includes dividing a frame of image data into a plurality of segments; calculating first fluctuation factors for the respective segments; calculating a second fluctuation factor for the frame; and identifying ones of the segments having a first fluctuation factor greater than the second fluctuation factor as active segments. | 10-03-2013 |
20130261781 | METHODS AND APPARATUS FOR GENERATING SIGNATURES - Methods and apparatus for characterizing media are described. An example method includes converting at least a portion of a block of audio into a frequency domain representation, dividing the frequency domain representation into bands, determining a characteristic difference of a first band of the bands, and determining a signature bit based on the characteristic difference, wherein determining the signature bit is performed differently based on whether an index of the first band has a first property. | 10-03-2013 |
20130268279 | METHODS AND APPARATUS FOR PERFORMING VARIABLE BLOCK LENGTH WATERMARKING OF MEDIA - Methods and apparatus for performing variable block length watermarking of media are disclosed. An example method to encode auxiliary data in audio data comprises selecting a frequency based on a code, selecting a block size based on the code, a combination of the block size and the frequency to represent of the code, encoding the code in an audio stream according to the block size and the frequency, and transmitting the audio stream including the encoded code. | 10-10-2013 |
20140105461 | METHODS AND APPARATUS TO COUNT PEOPLE IN IMAGES - Methods and apparatus to count people in images are disclosed. An example method includes analyzing frame pairs of a plurality of frame pairs captured over a period of time to identify a redundant person indication detected in an overlap region, the overlap region corresponding to an intersection of a first field of view and a second field of view; eliminating the identified redundant person indication to form a conditioned set of person indications for the period of time; grouping similarly located ones of the person indications of the conditioned set to form groups; analyzing the groups to identify redundant groups detected in the overlap region; and eliminating the redundant groups from a people tally generated based on the groups. | 04-17-2014 |
20140254801 | DOWN-MIXING COMPENSATION FOR AUDIO WATERMARKING - Example methods, apparatus, systems and articles of manufacture to implement down-mixing compensation for audio watermarking are disclosed. Example methods disclosed herein to compensate for audio channel down-mixing when embedding watermarks in a multichannel audio signal include obtaining a watermark to be embedded in respective ones of a plurality of audio channels of the multichannel audio signal. Such example methods also include embedding the watermark in a first one of the plurality of audio channels based on a compensation factor that is to reduce perceptibility of the watermark when the first one of the plurality of audio channels is down-mixed with a second one of the plurality of audio channels after the watermark has been applied to the first and second ones of the plurality of audio channels. | 09-11-2014 |
20140254876 | METHODS AND APPARATUS TO COUNT PEOPLE IN IMAGES - Methods and apparatus to count people in images are disclosed. An example method includes maintaining a history of instances in which a person is detected by a first image sensor and by a second sensor different than the first image sensor at approximately a same time, respective ones of the instances including a first coordinate at which a first person was detected via the first image sensor, and a second coordinate at which the first person was detected via the second image sensor; and, in response to first image data captured by the first image sensor including a second person at the first coordinate, determining whether second image data captured by the second image sensor includes the second person without comparing the first image data to the second image data. | 09-11-2014 |
20140279856 | METHODS AND APPARATUS TO UPDATE A REFERENCE DATABASE - Methods and apparatus are disclosed for updating an index of a reference data database. An example method includes, in response to receiving reference data at a reference database, inserting the reference data in a first portion of the reference database, updating a first portion of an index corresponding to the first portion of the reference database; and updating a second portion of the reference database by shifting the reference data from the first portion of the reference database to the second portion of the reference database, and after shifting, recomputing a second portion of an index corresponding to the second portion of the reference database. | 09-18-2014 |
