In this paper we describe a polynomial environment for binary image processing. A data structure in the form of a quadtree is proposed. We develop algebraic operators to do contour determination, approximation and thinning.doi:10.1016/0167-8655(90)90110-NKai Qian...
Using a convolution mask, we construct an edge detector. First, we construct a Gaussian mask that will be used to smooth the image and reduce the effect of noise on the edges. Then, using one of several edge masks, we extract the horizontal and vertical edges. These edges are combined an...

Template decompositionParallel processingA polynomial approach to the representation of gray images for machine vision is described. An algebraic system is developed where a polynomial in two variables with real coefficients represents a gray image and it is shown that most of the standard image ...

The recent decade has seen a tremendous escalation of multimedia and its applications. These modern applications demand diverse security requirements and i
There are limitations to the gap size and hence the signal bandwidth that can be handled with the algebraic approach. These arise from deteriorating conditioning of the encoding matrix as gap size increases [94]. Ill-conditioning boosts error in the signal and the signal model, causing three kin...
It was shown that local extrema over scale of homogeneous polynomial differential invariants DnormL expressed in terms of γ-normalized Gaussian derivatives are transformed in a scale-covariant way: If some scale-normalized differential invariant DnormL assumes a local extremum over scale at scale t0 ...
