Error analysis of M-channel DWT based method for orientation estimation of an inclined planar texture surface

Estimation of orientation of a textured planar surface using projective equations and separable analysis with M-channel wavelet decomposition

“…Additionally, M-channel wavelet transform provides a very direct and efficient way of multi-resolution and multi-channel analysis of image signals. In an earlier work [38], a theoretical error analysis of orientation estimation using 4-channel DWT was provided using simulated texture images. This current paper presents a theoretical formulation of the framework of projective geometry along with a wavelet-based algorithm for orientation estimation, followed by comparative results with a set of simulated and real-world images.…”
