做光学设计的同行都懂，好镜头是“调”出来的，也是“等”出来的。Zemax里反复改曲率和厚度，Lumerical里扫描周期单元的相位响应，一个参数组合跑下来，工作站转一整天是常态。更别提无透镜成像的重建调参、叠层成像的扫描校正，每一步都靠手动调试和 ...

Today:Early fog in the far southwest clears quickly. Most areas stay dry with sunshine and variable cloud, though northern and northeastern regions may see isolated showers. Light winds overall, ...

Hello, I'm Vladimir Mikhelev, a Machine Learning Engineer specializing mainly in computer vision. Today, I present my review of the current object-detection frameworks and provide my personal ...

Here, we propose an improved YOLOX-Tiny network, named YOLO-Tobacco, for the detection of tobacco brown spot disease under open-field scenarios. Aiming to excavate valuable disease features and ...

The timing of flowering plays a critical role in determining the productivity of agricultural crops. If the crops flower too early, the crop would mature before the end of the growing season, losing ...

YOLO, meaning 'You Only Look Once', is a popular model for real-time object detection. The YOLO algorithm divides images into a grid, with each cell responsible for detecting objects. YOLOv1, ...

Abstract: The aim of this work is to implement a Convolutional Neural Network (CNN) using a Python framework on Xilinx® Zynq® based Field Programmable Gate Array (FPGA). And the prototype is used to ...
