Specify dimensionality or make it a parameter, Array{F,N}. Otherwise it's an abstract type and will deliver slow performance.

I don't think this needs to be a field. You could define
eltype{F}(::Type{CENSURE{F}}) = F
eltype(censure::CENSURE) = eltype(typeof(censure))| response_matrix = reshape(hcat(responses...), size(img)..., size(responses)...) | ||
| minima, maxima = extrema_filter(convert(Array{Float64}, padarray(response_matrix, [1, 1, 1], [1, 1, 1], "replicate")), [3, 3, 3]) | ||
| features = map(i -> (minima[i] == response_matrix[i] || maxima[i] == response_matrix[i]) && ( response_matrix[i] > params.response_threshold ), CartesianRange(size(response_matrix))) | ||
| (grad_x, grad_y) = imgradients(img, "sobel", "replicate") |

Abstract type? keypoints = Vector{Keypoint}(0) or keypoints = Keypoint[].

Will users call censure directly? If so there needs to be a test. We should make sure that all filter types are tested, too.
