摘要： Methods and apparatus for identifying primary media content in a post-production media content presentation are disclosed. An example computer-implemented method to detect primary media content included in a secondary media content presentation disclosed herein comprises determining a first image corresponding to the secondary media content presentation, the first image comprising a plurality of image subregions, each image subregion representative of an inter-frame variation associated with a corresponding subregion of the secondary media content presentation, selecting a region of the first image comprising a plurality of connected image subregions of the first image together exhibiting a first type of inter-frame variation, and when a shape of the selected region of the first image corresponds to a predefined shape, processing a region of the first captured image corresponding to the selected region of the first synthetic image to identify the primary media content.

摘要： Hybrid active and passive people metering for audience measurement is disclosed. An example method disclosed herein to perform people metering for audience measurement comprises obtaining an image sequence depicting a scene in which an audience is expected to be present, comparing an image sequence signature representative of the image sequence with a set of reference signatures to determine a comparison result, and controlling audience prompting performed by a people meter based on the comparison result.

摘要： Methods and apparatus to detect differences between images are disclosed. An example method to identify image differences disclosed herein comprises electronically determining whether a difference between a first block of pixels of a sample image and a second block of pixels of a reference image is resolvable using a transformation operation, when the difference between the first and second blocks is determined to be unresolvable, but not when the difference between the first and second blocks is determined to be resolvable, including the first block in an unresolved difference region of the sample image, and electronically generating a difference signature representative of the unresolved difference region, the difference signature to identify the unresolved difference region of the sample image.

摘要： Methods and apparatus to detect differences between images are disclosed. Example methods disclosed herein to recognize different image versions include generating a first signature representative of a sample image, and obtaining a reference image associated with a second signature determined to substantially match the first image signature. Such example methods also include generating a third signature representative of a first region of the sample image corresponding spatially to a first region of the reference image associated with a first version of the reference image, the third signature being different from the first signature. Such example methods further include comparing the generated third signature and a fourth signature representative of the first region of the reference image to determine whether the sample image corresponds to the first version of the reference image.
