Divided Hadamard pattern illumination for fewer times measurements

A novel method for digital imaging with the Hadamard transform which is a popular technique in single pixel imaging is proposed. This method is suitable to reduce the number of measurements. In the method, barcode like patterns are used in stead of two dimensional patterns for the Hadamard transform. And then, a set of signal of the transform is obtained by optical measurement and post processing. Effectiveness of the method is shown in the paper.
