iradon - Inverse hough transform

Calling Sequence

img = iradon(R [,theta, filter])

Input Parameters

Output Parameters

Description

Function iradon reconstructs an image from the Radon transform. Currently, it uses the "Back Projection" algorithm.

If theta is a scalar, it is DeltaTheta, and R's angle interval is assumed to be 0:DelaTheta:180-DeltaTheta

Input parameters can be assigned in a "named" fashion, for instance: I = iradon(R,filter='no').
