Claim 5:
6. A computer system for tracking an object in an input video, comprising:
a memory; and
at least one processor configured to connect to the memory and to execute computer-readable instructions stored in the memory, wherein the at least one processor is configured to process the steps comprising,
training a classifier model using global pattern matching; and
classifying and tracking each target through online training including the classifier model,
wherein the training of the classifier model comprises,
separating a valid period in which all the targets are present in an entire consecutive period of an input video;
generating first training data after labelling a single valid period among the valid periods and training the classifier model; and
generating second training data after labelling a next valid period, generating accumulated training data by merging the first training data and the second training data, and repeatedly training the classifier model.
