Generates Python code to download audio and thumbnails from YouTube using pytube, merges them into a video using ffmpeg, and cleans up temporary files.
Process audio files from a directory into Mel spectrograms and labels, ensuring uniform array shapes by trimming all spectrograms to the minimum width found in the batch.
Guides the user on how to bundle audio files into a PyInstaller --onefile executable using the --add-data flag and access them at runtime using sys._MEIPASS.
Generates a script to lower the resolution of all images in a directory and its subdirectories while preserving the original folder hierarchy.
Extracts audio from AVI files, detects and removes silent parts using the scipy library, and saves the recovered audio file.
Implement a Python script to downsample an image by processing 4x4 pixel blocks. Each pixel in a block votes for the closest color in a colormap, and the block is filled with the most voted color.
使用OpenCV和NumPy处理具有透明背景的PNG图像。功能包括:将图像画布向外扩展200像素,在非透明内容外围添加100像素宽的白色填充,并在白色填充外围添加5像素宽的平滑黑色边框。黑色边框的平滑处理需使用距离变换(Distance Transform)和高斯模糊(Gaussian Blur)技术。
Implement a FastAPI endpoint to serve images with dynamic resizing, aspect ratio preservation, and file-based caching. Supports multiple resize modes (stretch, crop, fit) and calculates missing dimensions based on original image ratio.
生成Python脚本,利用FFmpeg将图片序列按3x3布局合并,或将合并图拆分。要求使用subprocess模块执行命令,并支持用户交互式输入路径。
Download YouTube videos with customizable quality and format options. Use this skill when the user asks to download, save, or grab YouTube videos. Supports various quality settings (best, 1080p, 720p, 480p, 360p), multiple formats (mp4, webm, mkv), and audio-only downloads as MP3.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
使用Python和OpenCV,基于HSV颜色空间和欧氏距离阈值对图像进行特定颜色的透明化处理,并利用形态学膨胀扩展透明区域,最终输出带透明通道的PNG图片。
Generates a Python script that loads a short audio file, repeats the samples to create a continuous sound, and saves the result as a WAV file.
Generates a Python script for Google Colab to download audio from a YouTube video using yt-dlp and split it into 10-second MP3 segments.
Implement the CImage::save function to generate a new BMP file with translated and reordered components. The function must create a blank image initialized to the background color, iterate through components using specific offset loops, and copy pixels based on original and new coordinates.
A Python function to load and preprocess paired screenshot and HTML files from separate directories, matching them by base filename (e.g., screen_13.png with html_13.html), resizing images, and normalizing pixel values for model training.
Generates a Python script to download YouTube playlists as MP3 files, including video thumbnails and artist metadata tags.
Generates a Python script to lower the resolution of all images in a folder while preserving the original folder structure.
Cleans video or audio transcripts by removing timestamp markers while preserving all spoken content.
