Python for Virtual Makeovers: Drawing Eyeliner with Facial Landmarks

Digital beauty filters and virtual try-on features are standard in modern applications, but how do they actually work under the hood? This text-only course guides you through the process of programmatically applying precise digital makeup using Python. You will understand how to detect facial features, work with coordinate structures, and use mathematical interpolation to draw smooth, natural-looking eyeliner on digital portraits. What you'll learn: Understand foundational computer vision concepts and facial landmark detection techniques; Map coordinate systems around the eye area using modern Python libraries; Apply mathematical interpolation to create smooth curves instead of jagged lines; Write clean, modular Python code with type hints to handle image coordinates; Implement realistic makeup transparency and blending effects on digital images. You will start with the basic terminology of facial landmarks and coordinate mapping, then progress step-by-step through reading, analyzing, and refining Python scripts that modify facial features programmatically. This course is designed for beginner Python developers and tech enthusiasts curious about image manipulation, with no prior computer vision experience required.
