Image enhancement remains an intricate problem, crucial for image analysis. Several
algorithms exist for the same. A few among these algorithms categorize images into different …

Morphological filter is a kind of morphological operation-based nonlinear filter. It is effective
in impulsive noise filtering and has been extensively studied in the past two decades. In the …

Image segmentation and image contrastenhancementare two useful techniques in image
processing. Generally, both techniques use contrast operators to transform an image and to …

In this paper a morphological contrast measure is introduced. The quantification of the
contrast is based on the analysis of the edges, which are associated with substantial …

We present a multiscale image approach for contrast enhancement based on a composition
of contrast operators. Contrast operators are built by means of the opening and closing by …

Mineral image is one type of crucial data for mineral research and analysis. However, some
mineral images are not clear in some cases. To efficiently enhance mineral images and …

Enhancing a microscopy mineral image to produce clear and rich details is important for
mineral analysis. To enhance effectively, an algorithm utilizing the constructed center …

3D reconstruction of airway trees can provide intuitive and useful information for
understanding human lung structure and function as well as assessing the presence of …

In this work a connected approach for morphological contrast enhancement is proposed.
The morphological contrast is based on the notion of toggle mappings. The notion of toggle …

This paper deals with the notion of toggle mappings. Toggle mappings have been proposed
by Serra in a framework theory for morphological contrast operators. In this paper, we …
