A New Inpainting Method for Highlights Elimination by Colour Morphology [chapter]

Francisco Ortiz, Fernando Torres
2005 Lecture Notes in Computer Science  
In this paper, we present a new application of the mathematical morphology: a single-image approach for the automatic detection and elimination of highlights in colour images.  ...  To eliminate the highlights detected, we use an image-inpainting method, by means of connected vectorial filters of the mathematical morphology.  ...  In this paper, we explain a new application of the mathematical morphology, an automatic and single-image system for the detection and elimination of brightness in colour images.  ...

Hierarchical morphological graph signal multi-layer decomposition for editing applications

Olivier Lezoray
2020 IET Image Processing  
Since morphological filtering operators require a complete lattice, a dedicated approach for the morphological processing of vectorial data on graphs is used.  ...  As state-of-the-art editing approaches decompose an image into several layers in order to manipulate them, they propose a hierarchical multi-layer decomposition of graph signals that relies on morphological  ...  The brightness values on a 1D image slice (indicated by the red line on the original image) are shown under each image ones for images, since SSIM and BRISQUE are defined only for images).  ...

In Field Detection of Downy Mildew Symptoms with Proximal Colour Imaging

Florent Abdelghafour, Barna Keresztes, Christian Germain, Jean-Pierre Da Costa
2020 Sensors  
This paper proposes to study the potentialities of on-board colour imaging for the in-field detection of a textbook case disease: the grapevine downy mildew.  ...  It introduces an algorithmic strategy for the detection of various forms of foliar symptoms on proximal high-resolution images.  ...  To a lesser extent, it also eliminates overly bright or overly dark pixels. This step is achieved simply by calculating the histogram of hue vales and then applying the Otsu threshold [22] .  ...
