Abstract
Estimating a vanishing point (VP) is a core problem for understanding three-dimensional scenes and autonomous navigation. Existing methods are essential to estimating VPs in indoor and urban environments. However, doing so in diverse, unstructured, changing, and unexpected field environments remains a considerable challenge. Traditional methods of estimating structural VP have some shortcomings as they rely heavily on feature-intensive computation, making them less reliable due to a lack of adequate structures in a field environment due to disorganized disturbances. Inspired by the oblique effect, neurons prefer to respond to horizontal and vertical stimuli more than to diagonal, which can help estimate VPs. This study proposes a methodology to estimate VPs from a monocular camera for a field environment. Local orientation features are assigned to clusters inspired by the oblique effect. By extracting end points of different clusters, virtual local orientation features are reshaped. Based on geometric inferences of orientation, a VP is approximately estimated using optimal estimation and self-selectability. No prior training is needed, and camera calibration and internal parameters are not required. This approach is robust to changes in color and illumination using geometric inference, making it a perfect fit for field environments. Experimental results demonstrated that the method can successfully estimate VPs. This study presents a groundbreaking approach to evaluating VPs using a monocular camera. Inspired by the oblique effect, our method relies on explainable geometric inferences instead of prior training, resulting in a highly robust model that can handle changes in color and illumination. Our proposed approach significantly advances scene understanding and navigation, making it an ideal solution for field environments.
期刊介绍:
Cognitive Neurodynamics provides a unique forum of communication and cooperation for scientists and engineers working in the field of cognitive neurodynamics, intelligent science and applications, bridging the gap between theory and application, without any preference for pure theoretical, experimental or computational models.
The emphasis is to publish original models of cognitive neurodynamics, novel computational theories and experimental results. In particular, intelligent science inspired by cognitive neuroscience and neurodynamics is also very welcome.
The scope of Cognitive Neurodynamics covers cognitive neuroscience, neural computation based on dynamics, computer science, intelligent science as well as their interdisciplinary applications in the natural and engineering sciences. Papers that are appropriate for non-specialist readers are encouraged.
1. There is no page limit for manuscripts submitted to Cognitive Neurodynamics. Research papers should clearly represent an important advance of especially broad interest to researchers and technologists in neuroscience, biophysics, BCI, neural computer and intelligent robotics.
2. Cognitive Neurodynamics also welcomes brief communications: short papers reporting results that are of genuinely broad interest but that for one reason and another do not make a sufficiently complete story to justify a full article publication. Brief Communications should consist of approximately four manuscript pages.
3. Cognitive Neurodynamics publishes review articles in which a specific field is reviewed through an exhaustive literature survey. There are no restrictions on the number of pages. Review articles are usually invited, but submitted reviews will also be considered.
