Purple fringing is an undesirable artifact in digital camera. This paper proposes a new purple fringing correction method using colorization in Yxy color space. In the proposed method, a chromaticity diagram based method is first used to detect the purple fringed region, and then this region is corrected by colorization. Colorization is an effective method for correcting purple fringing. The colors...
Developmental robotics focuses on how to endow robots with adaptive capabilities. Even though embodiment has been recognized as an essential factor for understanding development, there is yet not much work that investigates how the morphology of sensors and actuators shapes adaptivity and learning processes. Moreover, these studies are largely at an intuitive and qualitative level. In this paper,...
The standard morphological operators are (i) defined on Euclidean space, (ii) based on structuring elements, and (iii) invariant with respect to translation. There are several ways to generalise this. One way is to make the operators adaptive by letting the size or shape of structuring elements depend on image location or on image features. Another one is to extend translation invariance to more general...
