In view of problem that it usually lacks of fusion depth to combine moment invariants with other extraction technology on local invariant features, this article proposes the moment invariants based on SUSAN initial edge response, which provides a sort of organic integration for moment invariants and SUSAN edge detection algorithm. The combination point is to treat SUSAN initial edge response matrix...
In this paper, an adaptive interpolation method of digital image focusing on edge information is studied. The target is multi-level zoom ensuring image quality and keeping edge information. And this method is composed of three key models. (1) Accurate edge detecting model. Edge detecting model is the basic model to describe image features and the classic Canny edge detector is applied to get accurate...
Image enhancement is one of the important tasks in image pre-processing to improve the image quality for other applies. The traditional morphological enhancement operator cannot well address enhancement process for low illumination color image. In this paper, we present a new morphological operator based on graphic theory for the enhancement of low illumination color image. Firstly, the notable Weber's...
