By using a simple state feedback controller in three-dimensional chaotic system, novel 4D system is derived this paper. The equations are composed of nine terms including only one constant term. Depending on the different values term, new proposed has line equilibrium points or no points. Compared with other similar systems, newly presented owns more abundant and complicated dynamic properties. What interests us observation that if value term nonzero, it equilibria, therefore, Shil'nikov...

Event-based cameras are bio-inspired vision sensors that mimic the sparse and asynchronous activation of animal retina, offering advantages such as low latency computational load in various robotic applications. However, despite their inherent sparsity, most existing visual processing algorithms optimized for conventional standard dense images captured from them, resulting redundancy high when applied to event-based cameras. To address this gap, we propose a convolution operator tailored By...
