Claim One:
1. A system for processing images, comprising: voxel-ranking circuitry that ranks individual voxels using voxel data derived from physiological responses resulting from exposure to a plurality of corresponding baseline stimulus images; voxel selection circuitry that selects a portion of the set of ranked voxels based on their rank; and filter circuitry that creates two or more filters by determining which voxels will activate maximally in response to a feature presented in one or more stimulus images, then isolating each filter, the isolation of each filter based on the following equation: 
 φ i =∫r i ( t ) Sdt=∫r i ( t )Σ i φ i *r i ( t ) dt , where φ i represents an average filter response and expresses that a signal S is constructed from a weighted linear sum of neural firing rates, r i (t) represents variance-normalized average activity in a voxel at time step t, and S represents the stimulus image.
