Testing the Staple Object Tracking Algorithm in C++
Staple combines local HOG features and global color-histogram features for object tracking. This test has been completed in Windows, Ubuntu, and ROS environments and runs successfully.
ROS and STM32 Communication
Implemented bidirectional serial communication over UART between a host PC running ROS Noetic and an STM32F1 development board.
How to Set Up Alibaba Cloud OSS Image Hosting
I now publish blog posts on CSDN and my own website at the same time. However, I used to write and publish directly in the CSDN editor, which was an uncomfortable way to work. I still prefer a local Markdown editor such as Typora. This means I need my own image host, so screenshots pasted into the local Markdown editor are automatically uploaded to it.
Controlling a Stepper Motor with STM32
Driving a 42-series stepper motor with an A4988 chip, tested on the STM32F1 platform, with up to 16× microstepping.
Siemens TIA Portal V15 Download and Installation Guide

[Object Recognition] SIFT Algorithm: Theory
SIFT (Scale-Invariant Feature Transform) is an algorithm for detecting and describing local image features. The algorithm searches for extrema across scale space and extracts position, scale, and rotation invariants. These keypoints remain stable under changes in illumination, affine transformation, and noise. The main steps are (1) scale-space extrema detection; (2) keypoint localization; (3) orientation assignment; and (4) keypoint description and matching.
PyQt5 GUI Development Notes
The lab recently needed to process many spreadsheets, so I built a Python tool to help. The program uses PyQt5 for the graphical interface. This post records the full workflow—from installing PyQt5, to designing the UI, to writing code that drives the widgets, and finally packaging the app as an exe.
