Symmetry in Vision II

Dear Colleagues,

Symmetry plays a central role in many vision systems, both natural and artificial. Vision systems need to work in a world that is left–right agnostic, so it should be robust to left–right flipping. Symmetry can be an important cue to biological fitness and facial expression recognition, so detecting symmetry, even in the presence of out-of-plane rotations, is a useful adaptive trait. In spite of the apparent value of symmetry in vision, biological visual processing shows a degree of lateralisation rather than the two hemispheres processing information in exactly the same manner. There appears to be a balance between the cost of maintaining duplicate and redundant visual processing in both hemispheres and the gains of differential specialisation. Understanding of this, presumably optimised, pattern’s processing abilities of the right and left hemispheres could lead to new or improved understanding of the function of symmetry in nature. Measurement of symmetry/asymmetry is important in a number of domains, including aesthetics, biometrics, health, biology research or manufacturing quality control. Exploiting symmetry can help to make the training or application of vision systems, such as deep convolutional neural networks, more efficient and the resulting systems more compact. This Special Issue is devoted to cutting edge studies on how symmetry is, or can be, measured and exploited by biological and artificial visual systems.

Please note that all submitted papers must be within the general scope of the Symmetry journal.

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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. Symmetry 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 2400 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.
