It should be noted that in (23) and all equations in the rest of the paper that contain the term b′ 00, this term is the constant term of the polynomial B′(z1, z2), which is the stable version of the 2D PLSI polynomial B(z1, z2). Since we have assumed that bi j ’s are the coefficients of the 2D PLSI polynomial, the coefficients of the polynomial B′(z1, z2) are b′ i j ’s. Equation (46) in page number 920 is as follows:
