Special Issue Information

Dear Colleagues,

The comprehension of visual properties, both from a biological (microscopic) and a perceptual (macroscopic) point of view, is an active and fascinating field of research. Historically, the natural application fields of this research have been image processing and computer vision. More recently, the interest regarding human vision modeling has been renewed by the exponential growth of the research about artificial intelligence, where precise theoretical models can be intertwined with deep learning techniques to build artificial devices able to replicate visual features.

With this Special Issue, we want to provide a common setting to gather the most recent discoveries of scientists working in different disciplines related to vision and its applications.

This Special Issue is primarily focused, but not limited to, the following topics:

  • Biology and neuroscience of vision;
  • Vision-inspired image processing and computer vision;
  • Theoretical modeling of visual perception attributes;
  • Psycho-physical experiments in vision.

Discrete Krawtchouk polynomials are widely utilized in different fields for their remarkable characteristics, specifically, the localization property. Discrete orthogonal moments are utilized as a feature descriptor for images and video frames in computer vision applications. In this paper, we present a new method for computing discrete Krawtchouk polynomial coefficients swiftly and efficiently. The presented method proposes a new initial value that does not tend to be zero as the polynomial size increases. In addition, a combination of the existing recurrence relations is presented which are in the n- and x-directions. The utilized recurrence relations are developed to reduce the computational cost. The proposed method computes approximately 12.5% of the polynomial coefficients, and then symmetry relations are employed to compute the rest of the polynomial coefficients. The proposed method is evaluated against existing methods in terms of computational cost and maximum size can be generated. In addition, a reconstruction error analysis for image is performed using the proposed method for large signal sizes. The evaluation shows that the proposed method outperforms other existing methods.

In 1962, H. Yilmaz published a very original paper in which he showed the striking analogy between Lorentz transformations and the effect of illuminant changes on color perception. As a consequence, he argued that a perceived color space endowed with the Minkowski metric is a good approximation to model color vision. The contribution of this paper is twofold: firstly, we provide a mathematical formalization of Yilmaz’s argument about the relationship between Lorentz transformations and the perceptual effect of illuminant changes. Secondly, we show that, within Yilmaz’s model, the color space can be coherently endowed with the Minkowski metric only by imposing the Euclidean metric on the hue-chroma plane. This fact motivates the need of further investigation about both the proper definition and interrelationship among the color coordinates and also the geometry and metrics of perceptual color spaces.
