Tracking a person with an onboard camera is a very difficult and perhaps technically impossible if one camera is used. In this regard, real-life projects use a series of cameras to achieve the task. The advent of camera installed drone technology has made it possible for researchers and designers to resolve the tracking issues of a single or multiple stagnant devices. This paper presents a method that makes it possible for a drone to recognize hand gestures as control mechanism and follow the person who control it. Furthermore, the method assists in drone object detection using an integrated depth camera that provides video capturing. The OpenCV and Tello were used in this project. A stabilized depth video is for use with current person trackers like the OpenCV tracker. The estimated Tello pose deduced from vision to stabilize the depth image by warping it to a virtual-static camera. This method allows the Tello to obtain not only the tracked person's position and orientation but also their full body pose, which can then be used, for instance, to recognize hand gestures and alter the Tello's behavior. This work has a potential of contributing or enhancing cutting-edge applications such as hands-free photography and videography.
The study presented here consists of an entire framework for prediction of consumers behavior through the machine training of supervised learning methods. The strategy involves the following: data collection, preproce...

This paper aims to resolve the challenging problem of wide-angle novel view synthesis from a single image, a.k.a. wide-angle 3D photography. Existing approaches rely on local context and treat them equally to inpaint occluded RGB and depth regions, which fail to deal with large-region occlusion (i.e., observing from an extreme angle) and foreground layers might blend into background inpainting. To address the above issues, we propose Diffuse3D which employs a pre-trained diffusion model for global synthesis, while amending the model to activate depth-aware inference. Our key insight is to alter the convolution mechanism in the denoising process. We inject depth information into the denoising convolution operation with bilateral kernels, i.e., a depth kernel and a spatial kernel, to consider layered correlations among pixels. In this way, foreground regions are overlooked in background inpainting and only pixels close in depth are leveraged. On the other hand, we propose a global-local balancing approach to maximize both contextual understandings. Extensive experiments demonstrate that our approach outperforms state-of-the-art methods in novel view synthesis, especially in wide-angle scenarios. More importantly, our method does not require any training and is a plug-and-play module that can be integrated with any diffusion model. Our code can be found at https://***/yutaojiang1/Diffuse3D.

This paper designs a bionic sea turtle fin, which mimics the shape of the sea turtle's forelimbs and maintains an overall streamlined shape to reduce the resistance received by the outer side of the fin. This is of great significance and practical value for exploring new underwater propulsion methods and enriching and improving underwater propulsion technology. In terms of shape design, this paper uses Solid Works software to design the shape according to the contour of the sea turtle's forelimbs, and based on bionic principles, analyzes the flapping motion rules and propulsion mechanism of the sea turtle. To verify that the efficiency of the biomimetic turtle hydrofoil traction machine is higher than that of traditional traction machines, this study focuses on the optimization of the external shape configuration. The Flow Simulation plugin within the Solid Works software is applied to perform computational fluid dynamics CFD) simulations on the biomimetic turtle hydrofoil traction machine. Analyze the impact of different distances and different pitch angles between the fins on the motion performance; set the calculation domain, boundary conditions, residuals, inlet velocity, and sea conditions, etc., and perform simulation experiments on the bionic sea turtle fin tractors with different distances and different angles; analyze the obtained velocity cloud diagram and pressure cloud diagram. The results show that the ocean current resistance received by the bionic sea turtle fin tractor is significantly less than that of the traditional tractor, which verifies the feasibility of the bionic fin and its good application prospects.
