## Abstract The discrete cosine transform (DCT) method is well known for a highly efficient coding for still images. A problem in this method is that the block distortion is observed in low‐rate coding. The overlapping block transform (OBT) has recently been proposed, aiming at the reduction of the

In this paper we provide a fast, numerically stable algorithm to determine when two given polynomials a and b are relatively prime and remain relatively prime even after small perturbations of their coefficients. Such a problem is important in many applications where input data are only available up
