Erratum

The authors would like to bring to the kind attention of the readers the following corrections to the paper [1].

Equation (23) in page number 917 is as follows:
(1)

It should be noted that in (23) and all equations in the rest of the paper that contain the term , this term is the constant term of the polynomial , which is the stable version of the 2D PLSI polynomial . Since we have assumed that 's are the coefficients of the 2D PLSI polynomial, the coefficients of the polynomial are 's.

Equation (46) in page number 920 is as follows:
(2)
This equation may be corrected as follows:
(3)
