Method of processing image data in a connectionist network

A system comprising:

• one or more processors configured to process image data in a connectionist network comprising a plurality of units, each unit having a data input, a data output, and a processing parameter, processing of the image data comprising:
• receiving, as raw input data or input data processed by a preceding one of the plurality of units, a plurality of input picture elements representing an image acquired by an image sensor;
• determining, for a plurality of output picture elements, a plurality of offsets, each offset representing an individual location shift of an underlying one of the plurality of output picture elements;
• determining, from the plurality of offsets, a grid for sampling from the plurality of input picture elements, wherein the grid comprises a plurality of sampling locations, each sampling location being defined by a respective pair of one of the plurality of offsets and the underlying one of the plurality of output picture elements;
• sampling from the plurality of input picture elements in accordance with the grid, the sampling, for at least one of the plurality of sampling locations of the grid, comprising interpolating a respective one of the plurality of output picture elements associated with a respective one of the plurality of sampling locations when the respective one of the plurality of sampling locations is offside any of the plurality of input picture elements;
• and
• transmitting, as output data for at least a subsequent one of the plurality of units of the connectionist network, a plurality of sampled picture elements resulting from the sampling, the plurality of sampled picture elements forming the plurality of output picture elements.

A non-transitory computer-readable storage device comprising instructions that, when executed, configure a processor to process image data in a connectionist network comprising a plurality of units, each unit having a data input, a data output, and a processing parameter, processing of the image data comprising:

• receiving, as raw input data or input data processed by a preceding one of the plurality of units, a plurality of input picture elements representing an image acquired by an image sensor;
• determining, for a plurality of output picture elements, a plurality of offsets, each offset representing an individual location shift of an underlying one of the plurality of output picture elements;
• determining, from the plurality of offsets, a grid for sampling from the plurality of input picture elements, wherein the grid comprises a plurality of sampling locations, each sampling location being defined by a respective pair of one of the plurality of offsets and the underlying one of the plurality of output picture elements;
• sampling from the plurality of input picture elements in accordance with the grid, the sampling, for at least one of the plurality of sampling locations of the grid, comprising interpolating a respective one of the plurality of output picture elements associated with a respective one of the plurality of sampling locations when the respective one of the plurality of sampling locations is offside any of the plurality of input picture elements;
• and
• transmitting, as output data for at least a subsequent one of the plurality of units of the connectionist network, a plurality of sampled picture elements resulting from the sampling, the plurality of sampled picture elements forming the plurality of output picture elements.
