1. A method of compressing a transform associated with a feature space, the method comprising: obtaining the transform comprising a plurality of transform parameters; assigning each of a plurality of quantization levels for the plurality of transform parameters to one of a plurality of quantization values; and assigning each of the plurality of transform parameters to one of the plurality of quantization values to which one of the plurality of quantization levels is assigned; wherein one or more of the obtaining of the transform, the assigning of each of the plurality of quantization levels, and the assigning of each of the transform parameters are implemented as instruction code executed on a processor device.
