Képfelismerésben, or image recognition, is a field of artificial intelligence that focuses on enabling computers to interpret and understand the content of digital images or videos. This technology involves the use of algorithms and machine learning models to analyze visual data and extract meaningful information. The process typically begins with image preprocessing, where the raw image data is cleaned and prepared for analysis. This may include tasks such as resizing, normalization, and noise reduction.

Feature extraction is a crucial step in image recognition, where the algorithm identifies and extracts key features from the image, such as edges, textures, and shapes. These features are then used to train machine learning models, which can learn to recognize patterns and objects within the images. Common techniques for feature extraction include convolutional neural networks (CNNs), which are particularly effective for image data.

Once the model is trained, it can be used to classify new images or detect specific objects within them. This is often done using techniques such as object detection, where the model identifies and locates objects within an image, or image segmentation, where the model divides the image into distinct regions based on their content.

Image recognition has a wide range of applications, including facial recognition, medical imaging, autonomous vehicles, and quality control in manufacturing. As the field continues to evolve, advancements in machine learning and computational power are enabling more accurate and efficient image recognition systems.
