  • Online convolutional dictionary learning
    Patent number: 10409888
    Abstract: Systems and methods for an imaging system including a first sensor to acquire a sequence of images of a first modality. A memory to store a first convolutional memory matrix. Wherein each element of the first convolutional memory matrix is a convolutional function of correspondingly located elements of coefficient matrices of convolutional representation of the images of the first modality, and to store a first dictionary matrix including atoms of the images of the first modality. A processor to transform a first image of a scene acquired by the first sensor as a convolution of the first dictionary matrix and a first coefficient matrix, to update the elements of the first convolutional memory matrix with the convolutional function of correspondingly located non-zero elements of the first coefficient matrix, and to update the dictionary matrix using the updated first convolutional memory matrix.
