چکیده
|
The notion of quasi-affine frame was introduced by ron and shen in order to achieve shift-invariance of the discrete wavelet transform. in this paper, we have extended the notion of affine and quasi-affine frame on euclidean space r n to positive half-line. furthermore, we establish the relation between affine and quasi-affine frames on positive half line and the preservation of frame bounds when changing an affine frame to a quasi-affine frame is also shown.
