The intensive computational complexity, storage requirement, recognition of envelopes with parametric equations have rendered the standard Hough Transform interior to the intellectual mechanism of human's visual recognition. In this paper, a Modified Generalized Hough Transform is proposed which implements parametric equation of a straight line to establish relationship among various samples lying on a seismic reflector. It performs thresholding demarcation of interfaces in each window, establishment of continuity of interfaces from one window to another and mid-point smoothing. Based on its application on a zero-offset synthetic seismogram and a migrated CDP section presented here, the algorithm is found to be sensitive to the choice of window length. A time window of six samples or less with an equal degree of scrolling seems to the best suited for pattern recognition using this technique. However, a trade-off is necessary between the window length and the amount of overlap to obtain better reflection continuity.
