摘要： Systems and methods for quantizing a local descriptor in video fingerprinting applications are provided. In one or more embodiments, local features of a video are extracted and characterized by a set of feature dimensions. The feature dimensions are then quantized to yield a quantized local descriptor for the video. To introduce a degree of pseudorandom variation in the quantization grids, a cascaded random quantization technique is employed to quantize the dimensions, wherein a quantized value for a given dimension is used to quantize a next dimension in sequence.

摘要： An image comprising color pixels with varying illumination is selected. Instances of a repeating pattern in the image are determined. Illumination values for illuminated pixels at locations within instances of the repeating pattern are calculated based on pixel intensities of non-illuminated pixels at corresponding locations in other instances of the repeating pattern. The illumination variation is removed from the illuminated pixels based on the calculated illumination values to produce enhanced pixels. Color from the non-illuminated pixels at the corresponding locations in other instances of the repeating pattern is propagated to the enhanced pixels.

摘要： Systems and methods for measuring consistency between two objects based upon a rank of object elements instead of based upon the values of those object elements. Objects being compared can be represented by d-dimension feature vectors, U and V, where each dimension includes an associated value. U and V can be converted to rank vectors, P and Q, where values of U and V dimensions are replaced by an ordered rank or a function thereof. Analysis directed to the consistency between U and V can be accomplished by determining consistency between P and Q, which can be more efficient and more accurate, particularly with regard to illumination-invariant comparisons.

摘要： Systems and methods facilitating random number generation of hashes for video and/or audio are provided. In one embodiment, a system can include: a memory, and a microprocessor that executes computer executable components. The components can include a weighted distribution generation component that can generate a sampling distribution of a weighted combination of uniform distributions, and obtain a sample value from the sampling distribution. In one embodiment, horizontal regions of substantially equal area can be identified. The sample value can be obtained by selecting one of the horizontal regions, and uniformly selecting a coordinate from the horizontal region. The coordinate can correspond to a value on a horizontal axis of the sampling distribution, and the value can be equal to a sample value. The sample value can be employed to compute a hash employed in video and/or audio fingerprinting and/or in computing image descriptors for video.

摘要： A full-length fingerprint is generated for a video that represents characteristics of the entire duration of the video in a small amount of data. A plurality of subfingerprints for the video, each subfingerprint encoding features of a corresponding segment of the video, is accessed. A plurality of subhistograms is generated for the video, each subhistogram encoding a frequency of subfingerprint features for subfingerprints included in a subset of the plurality of accessed subfingerprints. A master histogram for the video is generated that encodes a frequency of subhistogram features for the plurality of generated subhistograms for the video. A hashing procedure is applied to the master histogram to produce the full-length fingerprint. Clustering can be performed on full-length video fingerprints for videos in a database to detect near-duplicate videos.

摘要： Proprietary rights logos are detected in a video. The video is divided into a plurality of regions that are analyzed for generic proprietary rights logo features. A confidence mask is generated that comprises a plurality of scaling factors, each scaling factor corresponding to a region of the video and indicating a likelihood that the corresponding region of the video includes a proprietary rights logo. The scaling factors of the confidence mask are applied to the video data to generate an altered video. The altered video is analyzed to determine a confidence measure that the video includes a reference proprietary rights logo.
