Hiện tại em cần viết một chương trình, theo dõi đối tượng theo màu. Bên trên là link hướng dẫn, nhưng em cần làm khác một chút là thay vì set up màu trong code thì làm một cái color picker, tức là khi click chuột vào màu nào thì chương trình sẽ focus vào màu đó, như thế sẽ dễ dùng hơn vì người dùng nhiều khi không thể nắm được thang màu. Hoặc đơn giản hơn, nếu làm cái color picker khó, thì có thể thay bằng thanh công cụ để chọn màu trước khi theo dõi giống như trong paint, ảnh em có để bên dưới Bác nào biết n...

...(or another widely compatible platform you prefer, as long as I receive shareable RVT and IFC files). All fixtures, pipe sizes, slopes, valves, and equipment must be shown in 3-D, correctly hosted to the architectural backgrounds I will supply.

Deliverables 1. Source code with clear, commented modules for detection, embedding generation, and similarity matching. 2. Pre-trained weights ready for immediate inference. 3. A small demo app or notebook that shows: – live webcam/CCTV inference, – batch search across a folder of photos, and – a simple REST or gRPC endpoint that returns face locations and a similarity score. 4.

Here’s what success looks like to me: • A modular data-collection layer that can stream pcap, NetFlow, or similar log formats into a preprocessing engine. • Feature-engineering and model-training code written in Python (feel free to leverage Pandas, scikit-learn, TensorFlow, PyTorch—whatever best suits the task). • A detection component that scores incoming traffic and raises alerts via a simple REST API or CLI output. • Clear documentation covering setup, retraining, and how new data sources—such as endpoint events or social-media threat chatter—could be plugged in later. Because this is time-sensitive, I’d like a first demonstrable bu...

...Infrastructure—and leave room for many more object classes as the project grows—then save every relevant frame straight into a MySQL database. Each stored image must be linked to the corresponding frame number and any detection metadata so I can later query, filter, and analyse the results. Once the data is stored, I want a lightweight viewer that steps through the saved frames in order, overlaying the detection boxes so I can visually confirm accuracy. OpenCV for frame extraction and display is acceptable; YOLO, TensorFlow, or another modern model is fine so long as the code is clean, well-commented, and easy for me to retrain with additional classes. To keep the hand-off smooth, please include: • A self-contained Python 3 script (or module set) ...
