1. A method of image processing, the method comprising: receiving camera data representative of an object; implementing, with a processor, a convolution operation on the camera data to generate filtered data representative of the object, the convolution operation being configured with singular value decomposition (SVD) kernel data; and storing the filtered data in a memory; wherein implementing the convolution operation comprises applying the SVD kernel data in parallel to a plurality of subsets of the camera data, wherein the object comprises a collimator; and storing the filtered data comprises configuring an imaging system in accordance with the filtered data, the imaging system comprising the collimator.
