Claim Text:
1. A non-transitory computer-readable storage medium having instructions embodied thereon, the instructions being executable to perform a method of detecting a temporally persistent pattern in a sequence of image frames, the method comprising: encoding individual frames of the sequence of image frames into spike packets using a sparse transformation, the sparse transformation being characterized by an information reduction parameter; determining a first spike within the spike packets, the first spike being associated with a first representation of the pattern, the first spike being characterized by a first time and a first ID; determining a second spike within the spike packets, the second spike being associated with a second representation of the pattern, the second spike being characterized by a second time and a second ID; determining a similarity matrix comprising a plurality of elements, individual elements of the similarity matrix being configured to be determined based on a comparison of the first ID and the second ID and a comparison of the first time and the second time; selecting a first vector from the similarity matrix, the first vector being associated with the first ID; and assigning the first vector to a category based on a distance measure from the first vector to one or more other vectors of the similarity matrix; wherein the assignment of the first vector and one or more other vectors of the similarity matrix to the category indicates the first representation being temporally proximate to the second representation.
