1. A method for simultaneously convolving a plurality of digital image data points into output data distributed in multi-channel output targets, comprising:

  • at least one processor implementing the following step of;

    A. multiplying a plurality of imaging data points from at least a portion of an input matrix with corresponding filter values to produce components of a plurality of output data points simultaneously;

    B. updating corresponding output targets with the components of the plurality of output data points from step (A), each output target having a plurality of channels; and

    C. repeating steps (A) and (B) until the output targets contain output data corresponding with convolved imaging data points from the input matrix.
