Zusammenfassung:A computer-implemented method of generating an image filter includes receiving a sample image that includes a foreground region and a background region. The method further includes extracting features from the foreground region and extracting features from the background region and determining a foreground covariance matrix based on the features extracted from the foreground region and determining a background covariance matrix based on the features extracted from the background region. The method further includes determining weights of the image filter by minimizing a cost function which includes a product of the weights and a linear combination including the foreground covariance matrix and the background covariance matrix.
