A method of processing source data

Abstract

There is provided a computer-implemented method of processing source data with a separable kernel to create output data. The method comprising: convolving a first lower dimension kernel of the separable kernel with the source data to obtain a set of intermediate values. For an intermediate value obtained for a target data point in the source data, the method comprising: combining the intermediate value with the content of a first memory location storing accumulated intermediate values for a first data point in the output data to create a final value for the first data point in the output data, wherein the final value corresponds to a value that the separable kernel would produce if the first data point were processed by the separable kernel; and storing the intermediate value in a second memory location related to a second data point of the output data, wherein the second data point requires the intermediate value to be processed according to the separable kernel.
