Those who frequently use Photoshop should be familiar with the Magnetic Lasso function, which is a human-guided cutout auxiliary tool. It is generally not called this in the R&D field. This edge extraction method is usually called Intelligent Scissors or Livewire. It was originally a Python framework for algorithm evaluation of an image segmentation project. I thought it was a bit interesting, so I expanded it a little, added a shell with PyQt, and simulated the magnetic lasso function to a very crude extent. Why is it rude: 1) Only the most basic edge search is achieved. There is no path cooling, dynamic training, mouse position correction, let alone curve closing, cutout, Alpha Matting, etc.; 2) No performance specifications are considered, just for the convenience of writing; 3) I have a very shallow understanding of Qt, and I still can’t write Signal-Slot, I don't know if the GUI is written reasonable; 4) No debugging. I did not conduct a deep research on the basic algorithm related algorithms, but I believe that the most loud algorithm in this type of application is from [1], which is also the main reference of this article. The basic idea is to see the picture as an unproof diagram. Advanced

Frequently Asked Questions and Solutions when Exporting PS as PDF: Font Embedding Problems: Check the "Font" option, select "Embed" or convert the font into a curve (path). Color deviation problem: convert the file into CMYK mode and adjust the color; directly exporting it with RGB requires psychological preparation for preview and color deviation. Resolution and file size issues: Choose resolution according to actual conditions, or use the compression option to optimize file size. Special effects issue: Merge (flatten) layers before exporting, or weigh the pros and cons.

PS "Loading" problems are caused by resource access or processing problems: hard disk reading speed is slow or bad: Use CrystalDiskInfo to check the hard disk health and replace the problematic hard disk. Insufficient memory: Upgrade memory to meet PS's needs for high-resolution images and complex layer processing. Graphics card drivers are outdated or corrupted: Update the drivers to optimize communication between the PS and the graphics card. File paths are too long or file names have special characters: use short paths and avoid special characters. PS's own problem: Reinstall or repair the PS installer.

Export password-protected PDF in Photoshop: Open the image file. Click "File"> "Export"> "Export as PDF". Set the "Security" option and enter the same password twice. Click "Export" to generate a PDF file.

Solving the problem of slow Photoshop startup requires a multi-pronged approach, including: upgrading hardware (memory, solid-state drive, CPU); uninstalling outdated or incompatible plug-ins; cleaning up system garbage and excessive background programs regularly; closing irrelevant programs with caution; avoiding opening a large number of files during startup.

PS card is "Loading"? Solutions include: checking the computer configuration (memory, hard disk, processor), cleaning hard disk fragmentation, updating the graphics card driver, adjusting PS settings, reinstalling PS, and developing good programming habits.

The Pen Tool is a tool that creates precise paths and shapes, and is used by: Select the Pen Tool (P). Sets Path, Fill, Stroke, and Shape options. Click Create anchor point, drag the curve to release the Create anchor point. Press Ctrl/Cmd Alt/Opt to delete the anchor point, drag and move the anchor point, and click Adjust curve. Click the first anchor to close the path to create a shape, and double-click the last anchor to create an open path.

Photoshop's advanced editing skills include frequency separation and HDR synthesis, and optimized workflows can be automated. 1) Frequency separation technology separates the texture and color details of images. 2) HDR synthesis enhances the dynamic range of images. 3) Automate workflows to improve efficiency and ensure consistency.

The reason for slow PS loading is the combined impact of hardware (CPU, memory, hard disk, graphics card) and software (system, background program). Solutions include: upgrading hardware (especially replacing solid-state drives), optimizing software (cleaning up system garbage, updating drivers, checking PS settings), and processing PS files. Regular computer maintenance can also help improve PS running speed.
