Summary: In our study, we successfully reproduced illusory motion in the rotating snakes illusion using deep neural networks and predictive coding theory. We further examined the properties of the network using a set of 1500 images, including static images and various types of motion illusions. The networks accurately classified illusory images and reproduced illusory motions similar to human perception. The networks could even detect anomalous motion vectors in static images where humans were unable to perceive any illusory motion.

Summary: This article describes a new visual illusion in which a smoothly translating object appears to rock around its own center during motion. This rocking line illusion occurs when the object passes through contrast boundaries formed by static background elements. However, the spatial scale of the display must be adjusted appropriately for it to appear. An online demo is provided where the effect can be experienced and relevant parameters manipulated.

Summary: A novel decor relation-based approach is proposed for measuring localized transverse flow velocity using line-scan optical coherence tomography (OCT). The new method allows for separation of the flow velocity component along the line-illumination direction from other components, diffusion motion, and noise-induced distortion. Verification was done by imaging flow in a glass capillary and a microfluidic device, mapping the flow velocity distribution within the illuminated area. This method has potential for mapping three-dimensional flow velocity fields in both ex-vivo and in-vivo applications.

Summary: We studied the Brownian motion of single 1 and 3 mu m particles moving along optical line traps oriented in the gravity axis. Using holographic optical tweezers, we formed finite linear traps and observed the non-equilibrium and equilibrium sedimentation of the particles. We also found that the optical forces along the linear trap do not significantly alter the Brownian motion of the particles.

Summary: We propose a four-line selective optical phased array (FLS-OPA) that improves the uniformity of radiated beam patterns. By using different grating periods and a thermo-optical switch, the FLS-OPA achieves different emitting angles in the vertical direction and a wide steering range in both vertical and horizontal directions.

Summary: In this paper, a new method for facial expression recognition is developed based on Local Motion Patterns (LMP) feature, which separates consistent motion patterns from noise. The method analyzes the elasticity and deformations of facial skin during expressions, and provides a unified approach for recognizing both macro and micro expressions. It also tackles challenges in in-the-wild expression recognition such as lighting variations and head pose changes.

Summary: Musculoskeletal disorders (MSD) are a prevalent work-related health issue, and hazardous postures pose a risk to their development. This study developed an inertial sensor-based approach to evaluate posture in industrial contexts, and found that traditional posture risk assessment tools do not consider posture risk differences among different operators.

Summary: This article introduces the design of a two-dimensional multi-element phase grating that exhibits spatially odd symmetry along one transparent diagonal line. The grating can achieve several intriguing asymmetric diffraction phenomena, including the elimination of equally spaced oblique diffraction lines and the selection of equally spaced oblique diffraction lines. These phenomena are explained through destructive interference between transmitted field amplitudes from paired and successive elements along the transparent diagonal line.

Summary: Color patterns are linked to the behavioral and morphological characteristics of animals, and play an important role in antipredatory strategies. This study finds a strong correlation between stripe patterns and body elongation in cichlid fish, indicating that the effectiveness of the stripes as an antipredatory strategy depends on body shape. However, genetic analyses show that stripes and body elongation segregate independently, suggesting that their correlation is maintained by correlational selection rather than genetic linkage. Furthermore, mate preference tests indicate that females do not differentiate between striped and nonstriped males, suggesting that stripes might be less important for species recognition and mate choice.

Summary: This paper proposes a video frame interpolation network based on both symmetric and asymmetric motion-based warping modules, which can effectively handle linear and non-linear motions as well as occlusions. The combination of symmetric and asymmetric warping results improves the reliability of intermediate frame reconstruction.
