Closed loop piecewise-linear histogram specification method and apparatus

摘要: Systems and methods that compute apply a real-time transformation between digital input output signals to achieve specified histogram. The systems implement predetermined (piecewise-linear) transfer function, coarse histogram collection, closed-loop algorithm produce target (or specified) Compact low-power contain controller the algorithm, signal processor function collection. use of piecewise-linear in conjunction with where number bins collected is equal segments, results significant reduction computational load communication bandwidth required by methods.
