Summary

This lecture, part of the Mexico-Germany Hybrid Summer School on Medical Informatics with AI, is delivered by Dr. Thomas Deserno. It provides an introduction to medical image processing and how machine learning and AI can be integrated into its pipelines. The lecture begins with a motivation using a visual puzzle to illustrate the challenge of image understanding. It defines an image in terms of pixels and structures, and outlines the typical steps of medical image analysis: formation, enhancement, feature extraction, segmentation, and classification. The speaker emphasizes the importance of reducing information while preserving relevant details. He discusses the unique challenges of medical images, such as high variability, lack of ground truth, and the critical consequences of errors. The lecture covers image enhancement techniques including histogram transforms, convolution, and Fourier transforms, with examples. It then introduces feature extraction, focusing on texture and shape features, and mentions methods like co-occurrence matrices, fractal analysis, and curvature scale space. The presentation is didactic, using examples from dental X-rays, bone tumors, and other medical images. It concludes by setting the stage for understanding how machine learning can be meaningfully integrated into these processing steps.
