Abstract:
1. An apparatus for content-processing filtering in an operational phase that is capable of learning from a training set of known discrete content signals and desired transform values by finding the best coefficients for a transform in a learning phase, comprising: at least one memory having stored therein at least one transform; at least one processor; and computer-readable instructions, which when executed by said processor, apply said at least one transform to received content data; wherein the at least one transform comprises linear combinations of pre-selected non-linear functions, and wherein the at least one transform is in the format of: where: s wherein the functions have the property of ƒ(as+c)=f(s) for each scalar a and c values where s+c denotes the vector (s as well as and the desired filter function is in the format of:
