• We generalize polar harmonic transforms for pattern description/recognition.
• The generalization maintains beneficial properties of existing transforms.
• The completeness of the corresponding basis sets is proven.
• The numerical stability of the computation is discussed.
• The new generic transforms have superior performance to comparison methods.
