Abstract: A video detection system and method compares a queried video segment to one or more stored video samples. Each of the queried video segments and stored video samples can be represented by respective digital image sets. A first and second comparison comprises comparing a set of low and high resolution temporal and spatial statistical moments in a COLOR9 space, and eliminating file digital image sets that do not match the queried digital image set. A third comparison generates a set of matching files by comparing a set of wavelet transform coefficients in a COLOR9 space. RGB bit-wise registration and comparison of one or more subframes of specific frames in the queried digital image set to a corresponding set of matching file subframes determines queried subframe changes. In the event of a change in a queried subframe, the changed subframe is added to the set of matching file subframes.

Abstract: A feature used in face detection can be applied to an image portion and can be scaled to fit differently sized image areas. If a feature is positioned with respect to an image area such that a vertex of the feature is aligned with a non-integer pixel location, at least one dimension of the filter can be rounded. A dimension to be rounded further can correspond to a directional component of the feature. For instance, contrast regions within the feature can be arranged horizontally, such that the vertical dimension represents a directional component. A rounding rule associated with the feature can be used in rounding a dimension corresponding to a directional component, such that a size ratio between the contrast regions is maintained. In some instances, the rounding rule can specify a factor that is a positive integer determined based on the number of contrast regions in the feature.
