Special Issue Information

Dear Colleagues,

Color image processing embraces two decades of extraordinary growth in its technological applications. Color images contain a wide variety of information and are more complicated than gray-scale images. As human vision is more sensitive to color than gray levels, the importance of color information in digital image processing is therefore greater than ever. However, it does require more memory to store data and longer execution times to process them. Despite its challenges, it provides a path for analyzing images with numerous practical applications, such as automation systems, robotics, visual communications, video surveillance, face recognition, object detection, content-based image retrieval, and medical imaging. Currently, the majority of methods for color image processing are based on gray level images, while some are exclusive to color images. With regard to the latter type of analysis, the main techniques treat each pixel as a three-tuple vector, and apply vector-processing techniques without decoupling color components. Moreover, color representation is sensitive to illumination, so two colors, with the same chromaticity, can be recognized as different if they have a different lighting intensity. Because of the undoubtedly higher level of complexity, the latter category has received much less attention from the scientific community. The transition from scalar- to vector-valued image functions has not yet been generally covered in the scientific literature. Key future contributions to this field could ideally aim to fill this gap, in order to contribute to the literature and improve current color image processing techniques and their practical applications.

We therefore look forward to receiving contributions aimed at deepening the discussion on this important topic.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Imaging is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
