Abstract:
1. An image processing method comprising: accessing a coefficient for each of a plurality of coefficient groups in a kernel matrix, wherein kernel coefficients that have a common value form members of a given one of said coefficient groups, wherein each kernel coefficient has a corresponding entry in a data matrix that comprises pixel values, and wherein at least one of said coefficient groups includes at least two kernel coefficient members; for each coefficient group, summing the value of each entry in the data matrix that corresponds to kernel coefficients in the coefficient group to generate a summed value for each coefficient group; for each coefficient group, multiplying the summed value by the coefficient of the coefficient group to determine a final value for each coefficient group, wherein a particular coefficient group of the plurality of coefficient groups has a particular summed value and a particular coefficient, wherein the particular coefficient is a sum of at least a first term and a second term where the first term has a value of 2 determining a new pixel value for a particular entry of the data matrix based at least in part on the final value for each coefficient group; wherein the method is performed by one or more image processing devices comprising a storage circuit.
